Title: Revelator Speaker Kit
Post by: Trafford on 1 May 2007, 08:24 pm
I am looking for a monitor speaker kit that will dip nicely into the 40's with tight base and clean highs that can do justice to Classical music and jazz but also allow me to rock out should the spirit move me. I would also like it to be an easy load to drive. I have tried to avoid 4 ohm speakers or the less efficient ones. I have looked at the kits from GR Research, Selah, RAW, Ellis and others. The one that looks most promising is the Ellis 1801b or the upcoming "C" version. The only downside would appear to be several comments on that speaker not being the particularly good with rock music (not sure how true that actually is), especially the harder stuff.

It appears that the Revelator line from Scanspeak performs very well and I have looked for something with the 7" mid woofer to get the better base performance. Selah has the SSR but I would prefer not to use a ribbon tweeter. I found the Leda Resources Eminent kit during my surfing but the site seems to be badly out of date and the unit uses the smaller mid woofer anyway.

Is there a monitor kit somewhere employing the Revelator woofer and tweeter that will give me what I am looking for? Is there another kit with quality components that can meet my needs? Or is the 1801b (or 1801c) the answer to my problem? The speakers I currently have are NHT's, Onix Rocket's, Athena's and none of them give me what I am looking for in my two channel set up.

I would like the kit to be under $1000 and preferably under $750 including the cabinet. This will also be my first attempt at speaker building so I guess a two way is preferable or at least a kit that includes the front baffle.

I appreciate any suggestions. Also if this is posted in the wrong forum please let me know. I looked over all of them and this one seemed to be the closest.

Trafford,
Well it appears you have done some research and found some great manufactures.  All will have their

If you are interested in SSR, give Rick a call as I'm positive he can subsitute something in lieu of the ribbon tweeter and come up with a winner.

You may also want to talk to Jim Salk about an Usher design he builds.  Not sure if he is willing to do a kit for it though?

Not sure I'd say the 1801 doesn't rock well; people may be talking more about it being a fairly revealing speaker and rock isn't always the best recorded, so you kind of get the "garbage in-garbage out" message.

Good luck,
Jeff

edit: forgot to include what Jim offers

Ladydog is correct.

Speaker design is all about balancing trade-offs. 

The 1801 is an excellent speaker.  The Seas Excel W18 midwoofer is extremely detailed and accurate - one of the very best there is.

The ScanSpeak Revelator driver will play lower than the W18 and have a slightly "warmer" sound, but it will not be nearly as detailed. 

If you want to hear the subtle detail in a recording, the 1801 is the way to go.  If you want deep bass and aren't concerned about getting the most out of your recordings, a ScanSpeak-based design would be the way to go.

Most often, there is relatively little detail in a rock recording and most of them tend to be highly compressed.  Often they are mixed using small "radio-type" speakers since they are primarily mastered for radio play. 

So if you listen to a lot of rock music, the 1801 might not be for you.  But if you prefer a wide range of music, are willing to give up just a little bass extension and want to hear well-recorded music in all its glory, then go for the 1801.

I hope this helps.

- Jim

PS - I'm sure Rick would modify his design for you.

Second this.

I listened to W18 but didn't like its dry presentation. I prefer a slightly warmer sound. I listen to a lot of classic rock and indian classical music, so a warmer sound suits my taste. YMMV

Post by: Trafford on 1 May 2007, 11:56 pm
Wow, a lot of great information. Thank you everyone!!!!!!

I know what I think is "dry", "detailed" and "warm" but I may be using these terms completely incorrectly. To me, the Onix Rockets are warm but not detailed. The NHT's seem to be the same way unless you dump a lot of power into them, then they seem to open up and become more detailed. The Athena's seem very warm and soft but they give me the impression that I am missing a lot in the music.

I have made most of my judgements from reading sites like this but I really have yet to hear any of these speakers. Are there any mass produced speakers that employ the Revelator or the Seas woofer that I can sample at the local stereo shop? I live outside of Pittsburgh so my choices are limited by reasonable.

I was interested in the Vifa XT/ Scanspeak Revelator combo. I know the XT is used in Polk speakers but I am not sure who employs the Revelator, the Seas or the Hiquphons. Can anyone give me a hint?

Once again thanks for the help from a novice that would like to take the next step in the audio world.

To really rock out in a large room you will need a 3-way in my opinion.  But look at www.zaphaudio.com anywho, find the Seas L18/27TBFC/G design.  I think you will find what you are looking for there. 

Also try http://www.rjbaudio.com/, http://htguide.com/forum/forumdisplay.php4?f=39, and www.diyaudio.com.

These sites might also be worth exploring.   I apologize if I just made your decision 1,000,000 times harder.

The Revelator driver doesn't lack for detail, it is easily the most detailed of the ScanSpeak line of drivers. It is definitely a woofer to be considered. That said I chose to go with Selah's Tanzanites that use the SEAS Excel 7" driver. I'm not a huge fan of the Vifa tweeter (or any metal dome tweeter) and went with the Fountek ribbon that is Rick's standard tweeter choice. These are 3-way speakers with the Morel dome midrange. This was a better match with my objective of a sealed with sub setup. Without a sub you may want the ScanSpeak as they are known for their bass. Talk to Rick he'll setup you up with pretty much whatever you want.



 
Title: Re: Revelator Speaker Kit
Post by: LadyDog on 2 May 2007, 12:20 pm
Yep, bet the ow1/ss combo would be pretty sweet.  Can't imagine Rick would have much of a problem getting them to gel either.  As he could with other tweeters such as peerless, seas, scan speak.......your pick.  With Rick it is just a matter of choosing a budget, drivers, and what you are trying to accomplish.  He'll get it to work.

I would give this kit some serious thought. Rick will adapt it to fit your specific wants/needs.

Yup .. i was told that .75 cu ft PE cabinet would fit these designs just fine.
Ask rick to put OW1 instead of the ribbons.

Actually it's .75 cubic ft. sealed or 1 cubic ft. ported. The Scan-Speak woofer can work with a variety of tweeters and is very flexible in that regard. I believe it is simply the best 7" driver available for 2-way applications.
Title: Re: Revelator Speaker Kit
Post by: jsalk on 2 May 2007, 04:53 pm
Well, we could certainly make the Usher 2-way available as a kit.  However, the Usher woofer is a "clone" of the ScanSpeak 8545.  And while it does a respectable job when compared to the 8545 (especially considering the price differential), it is no competition for the Revelator drivers.  So I would steer clear of this option.

I am not sure I would go so far as to say the Revelator is the best driver there is for a 2-way.  It would certainly rank among the few candidates for this title.  But much depends on what you are looking for in a completed design.  In some applications, the W18 could be a superior choice. And there are a few other drivers that could compete for the title.

But in this application, my guess it that the Revelator, perhaps combined with the OW1, would be an ideal solution.  And I am certain Rick could hook you up with everything you need to make it happen.

Post by: Trafford on 2 May 2007, 09:46 pm
Once again I have to say, "Wow, great info!"

I had assumed to go with a ported design to get better base response.

From the multiple sites I have read it seems that the Seas Millenium, the Scanspeak 9500 and the User 9950 got some good opinions expressed about them. I'm not sure how all of these would compare to the OW1. I also don't have a good feel for what price point these options represent.

I don't want to break the bank, I just want a speaker that sounds like I did. I am also concerned that this is my first project and I don't want to spend a bunch and then screw it up. Sites like this give me some confidence but reality can bring you down to earth pretty quick.

Am I on the right track with the Revelator mid-woofer and the tweeters above?
Title: Re: Revelator Speaker Kit
Post by: Danny Richie on 2 May 2007, 09:51 pm
Ask 100 people even among loudspeaker designers and you'll get plenty of different answers about drivers.

I have worked with just about everything out there and have found most drivers to be a series of tradeoffs. Having worked with a lot of different drivers does allow me to derive many personal listening impressions. I can agree some opinions here, but disagree with others.

I have also been a dealer for PHL, Focal, Raven, etc.

(http://www.gr-research.com/images/revelator-phl.jpg)

I have worked with Eton driver and  Aurium Cantus ribbons offer a couple of kit using those.

(http://www.gr-research.com/images/criterion.jpg)

I current stock planar magnetic drivers from BG Corp and they rank among my favorites for high frequency drivers.

The ScanSpeak Revelator driver will play lower than the W18 and have a slightly "warmer" sound, but it will not be nearly as detailed.  

I got the same impressions from the Revelator woofers. They played low for a small woofer but really lacked resolution in the upper vocal region on up. I worked with them as soon as they were released.

(http://www.gr-research.com/images/scanspeak.jpg)

I really didn't care much for them.

I don't know which one you are referring to but can't really see any of them making it that high up on my list. Some of the latest Usher woofers that I have worked with sounded better to me.

I do like some of their tweeters though.

Nothing against the 1801, but the Seas Excel woofers have never been too high on my list either. I find them a bit dry and lifeless, lacking in any natural qualities. They sound un-involving and lack any lushness or musicality. I have worked with most of them including the W18E and W18Ex models. There is also some nasty break up to contend with that is almost impossible to completely get rid of.

Here was an design I did several years ago for a customer.

To me, the Onix Rockets are warm but not detailed.

Which Rockets do you have? There are upgrades available for them that transform them quite a bit.

Dipping nicely into the 40Hz range, and capable of handling rock music well might be pretty tough order to fill for a small two way. You might have to consider a floor standing design.

My question would involve your room size and acoustics before making real recommendations. Your electronics will make a different too.
Title: Re: Revelator Speaker Kit
Post by: DSK on 3 May 2007, 02:36 am
Just as Danny agreed and disagreed with previous opinions, I find myself agreeing and disagreeing with Danny's opinions  :lol:

I agree on the preference for ribbons. I've listened to the Vifa RR and the Scanspeak RR and much prefer the Fountek NeoCD3 ribbon tweeter. To me it does a better job of bringing the performance to life and putting you in the room with the performers. It also has pretty good dispersion for a ribbon. I suspect that it would land on more audition lists if it was more expensive.

I also agree re the SEAS Excels. I too found them a bit dry, and lacking body, emotion, and musicality. They initially sound detailed and vivid but to my ears the detail is pushed forward at the expense of the overall presentation, body and dimensionality.

I disagree re the Scanspeak Revelator midwoofers, at least on the 18W8531G00 anyway. I find this midwoofer to have wonderful detail and musicality, sounding more natural and balanced than the Excels. The detail does not jump out at you, but it is there as part of a coherent and balanced whole ...just as it was at the original performance. It is a master at putting you in the room with the performers. Scanspeak describe it as their "absolute premium reference level, wide bandwidth driver". It has the bass performance of the SS 8545 (used in many very expensive speakers) but with a much more refined midrange and is well behaved to 5khz (not requiring notch filters). It readily highlights any changes or tweaks in your system, or differences in recording styles and quality. I wouldn't describe it as warm per se (as in smoothed over) though it is more full bodied and natural sounding than the Excels. To me, the Excels are more 'hifi' whereas the 8531G is more 'natural' and 'musical'. Perhaps I should also mention that I am using it in a very rigid, sealed enclosure (Selah SSR) and have not heard it in a ported box.

As always YMMV as we all hear differently and drivers will always sound different depending on the particular implementation. Good luck!  :D
Title: Re: Revelator Speaker Kit
Post by: Trafford on 3 May 2007, 01:03 pm
I can see there is a lot of differences in opinion on the various drivers just like there are on the various speakers. That's why I was looking for some mass market speakers that have some of the drivers in them so I can hear them to see what I prefer.

I have the Rocket 550 MkII's (front and rear), RSC200, RSS300, UFW-12 in a home theater set-up driven by the MPS-1 in a 15'x27'x8' carpeted room. They replaced a NHT VS-2 set-up with a Velodyne F1200. The NHT's seemed to only really give me what I was looking for when driven to very loud levels otherwise they seemed to polite to me. The Rockets seem the same way but they have a little more of the detail I am looking for.

The room I have set-up for two channel is my livingroom and any item in there must get the approval of the boss. That is why I wanted a monitor. I may be able to get the F1200 in there but I doubt she would go for floor standers. The room is 16'x24' with a cathedral ceiling. I don't need ear splitting sound levels but this is the system for music for that part of the house. I woudl initially be running this system with an old NAD 40W integrated and I plan to upgrade to the Onix X-Empower or some other class D integrated in the near future.

I want to hear what I have been missing in my CD collection and I want a solid low frequency foundation for the music. I listen to lots of blues, some jazz, some rock and a little classical. Any recommendations would be appreciated. I would like to spend less than $1000 but preferrable less than $750. That is what is inspiring my desire for DIY, plus it sounds like it could be a lot of fun.

I appreciate all of the input, recommendations and other help.

Danny,

What experience do you have with the PHL drivers?  I was going to suggest those if a 3-way design was a possibility.  I think the PHLs will offer exactly what Trafford is looking for. 
Title: Re: Revelator Speaker Kit
Post by: LadyDog on 3 May 2007, 02:17 pm
Trafford,
As you have already seen, everybody is their own movie critic when it comes to this stuff. 

Certainly is a good idea to go and listen to as many speakers as you can, but please keep in mind that much of it is room and system dependent.  So while speaker "A" may sound good at one store or a person's house, it may not sound as good at another's place with their gear.

Not to discourage you from a kit, but there are actually some pretty decent speakers on the "used" market.  Shouldn't have a problem picking up something in your budget from Tyler Acoustics, Pro-Ac, Usher, Dynaudio, Totem, Silverline, or Aci, just to name a few.

Btw, where are you located?  May help with seeing who is close to you with what gear.

Post by: Danny Richie on 3 May 2007, 03:32 pm
DSK, I guess of the drivers I mentioned, and aside from some of the newer Usher woofers, I'd prefer the paper cone Scan Speak units. I think if the crossover point is low enough they are not too bad. That is a lot of cone mass to be throwing around. By my comparisons to other woofers the upper end resolution just wasn't quite as good.

The real disappointing thing was that when I finished up this design...

(http://www.gr-research.com/images/scanspeak.jpg)

I A/Bed it next to a pair of our A/V-2's. Granted the A/V-2 had better caps in it and was well burned in, but the comparison was way too close. Differences were marginal at best. Considering the cost differences in the drivers it was embarrassing.

The cost was a major put off. $200 plus per woofer? Give me a break. They don't cost that much to build.

I can have a sample of one just like it here in about 10 days if I was interested in it. I can have it made anyway I want it, with pretty much any motor structure design, and the same cone from the same vender. I can get it for about 1/10 of the price too.

(http://www.gr-research.com/images/sscopy.jpg)

Trafford, There is a pretty serious version of the X-LS coming out in a few months. It is the X-LS EX version. It will be a really serious mini-monitor, look nice, and cost $299 a pair plus shipping. This has a really good tweeter in it too. Easily as good as a Scan Speak 9500 or Usher 9950. Add a cap upgrade to it and a sheet of No Rez, and I'd put it up against any mini monitor out there. It would be a good one to consider. Yes I designed it, but I have designed a lot of speakers, and this one really is that good.

With the money saved you could add a small sub too.

Quote

I used to be a dealer for them and have worked with most of the 6.5" models, 8 ohms and 16 ohms. They are pretty nice overall. I wouldn't pick them over our M-165X though, especially considering the price.
Title: Re: Revelator Speaker Kit
Post by: Trafford on 3 May 2007, 04:01 pm
Danny will the X-LS EX have the M-165x woofer? Are there upgrade kits from AV123 or do I have to buy individual components? The price sure is attractive. Did you design any of their other speakers (Rockets or Reference)? That would give me a little idea of how your designs may sound.

How do the X-LS EX's compare to the X-Pro and the SWG that I see mentioned on their boards? I think those are more expensive but I couldn't tell what the relative quality would be, not to mention the sound differences.

I love the finish on my 550's and more importantly, the boss loves it. Putting this two channel set-up in one of her favorite rooms means that the cabinet must look really good. As a first-timer in speaker building, I am very nervous about how good of a job I can do on the box. If I can get one of those X speakers at a reasonable price in a finish she likes, that might solve all of my issues. I can then take my time and choose a kit to play with that I don't have to worry about appearance issues.

Wow, I think I'm confusing myself but it sure is fun. This is a great time to be in this audio hobby.

I really do appreciate all of the information and the suggestions.

I designed all of the X series products from the drivers to completion.

I designed networks, and box design for the RS450 and RS760 models.

I designed an upgrade for the RS850, RS1000, RSC200. These are now the standard networks offered through AV123.

I designed an upgrade for the RS550 and RS750 that is offered through the Skiing Ninja.

I also designed the crossover and driver layout of the Strata Mini.

Then of coarse my LS-6 and LS-9 line source kits are going to be offered through AV123 fully assembled.

If you can get her to go for a set of floor standing speakers then the new X-Statik will be the bomb. New EX version tweeter, dual 16 ohm woofers in an open baffle, plus another pair of woofers right below to handle 200Hz and down...  Well within your budget too.

Wow Danny those speakers look awesome but I don't think I can afford the jewelry it would take to bribe the boss to let those in the livingroom. She has carefully selected every piece of furniture in there and I don't think she would pick speakers with that large of a footprint. She liked the "wooden speakers on the black metal stands" but wasn't real keen on the 550's when I moved them into the livingroom. The rosewood clashed with her oak furniture. I may still give it a shot, you just never know what might strike her fancy. If I can get a good monitor I can supplement it with the Velodyne F1200 assuming I can sneak that past the boss or hide it behind a chair or end table.

I never realized you had input on so many AV123 products. Of course I never knew who the design people were. Is Sean at Skiing Ninja the same Sean form AV123?

Ladydog, I am located in southwestern PA in the town of Trafford. I appreciate the comments about the impact of the other equipment and the room parameters.

About 20 years ago I heard a friend's Ohm Walsh 4's with his Carver receiver and was blown away compared to my Cerwin Vega D-9's and my Technics receiver. I have always wanted a nice two channel set-up that can inspire me the same way. I thought building a pair of speakers may or may not inspire me with sound but it would at least inspire me with pride. But that "appearance and price" thing keeps sneaking into the equation and the memory is probably better than the reality.
