New Orleans Crew that would be Me and Henry, what a great time indeed. This was both of ours first experience at the RMAF. I have to say you are spot on with your review although I would have to agree with John about the rooms and everything else going on in them having allot to do with it.

Wish we had more time to listen to the pAudio driver. I was like holy sh*t when the first track from O Brother, Where Art Thou came on. Ya'll are really on to something there. Let us know when ya'll get that crossover fully tweaked. Need I not forget the Cyndi Lauper track that John loved so much too

Wish now that I would have stumbled in to room 586 to here the pAudio there too.

Like you said the neighbor wasn't too happy when we left your room, John was like were done now sorry

I agree with opnly bafld on the small ob, more juice would make them rock.

It was a pleasure meeting you , Lin, and Rev. John.

Brad

That P.Audio has me intrigued. Is it the 1" or the 2" compression driver version? Is it possible to swap out the compression driver with something else?

Sorry guys, but the enclosures for the big open baffle line sources just weren't ready yet. I had to fall back to using some LS-9's in that room.

We also had a very specially open baffle design to premier in my smaller room at the Marriott, but it wasn't ready yet either. We then went to plan B and showed the X-Statik's that I designed for AV123 in that room. It used an open baffle MTM upper section. It was proclaimed by many as the best value at the show. At only $799 a pair maybe it was the best value at the show.

Major magazine reviews will be out shortly.

Hi Danny,

Very cool looking speakers! I can't believe the price and look forward to hearing them in person someday. I'm thinking about having a get-together at my home in December and will try to find a local person with the X-Static speakers willing to bring them over. Or I'll see if Mark Schifter can help point me in the right direction. They look awesome and I've only heard good things.

Cheers,

Jack

I will also note that if you looked in at our room on Sunday you would have seen that we were showing the small Tyler Acoustics mini-monitors with one of our Direct Servo subs.

We only played the X-Statik's Friday and Saturday. In fact I wasn't real happy with the sound on Friday. We didn't have the Direct Servo sub there until Saturday (Friday night) and due to the limited number of hours on the X-Statik's they sounded pretty fresh that first day. I asked for a burned in pair, but I don't think that they were. They sound fresh out of the box to me.

By Saturday they had really smoothed out and with the sub we were producing full range sound. I measured the X-Statik's and Direct Servo sub to make sure they were in phase with one another (I took my Clio system). The measurements showed them flat to 20Hz.

Another cool looking speaker. Are those Seas woofers? If so, are they paper or magnesium? I hope to get someone local who has a pair of those to try also!

Cheers,

J

Jack,

It the get together is large enough and Mark has the speakers in stock then he may be willing to demo out a set to you.

The drivers used in the new Tyler Acoustics line are all new proprietary models made just for Tyler Acoustics, and the woofers do use a paper cone.

It looks like the X-Statik's made somebody's top ten...

dweekie...

The driver Pano is slobbering over uses a 3" h.f. driver with a 1.4" exit... a dual stage radial phase plug .. plus an acoustic lens... it is quite advanced and on it's own would be a $300 plus item. FS is just above 500 Hz and it is usable out to just shy of 19K. With the wave guide cone... mid band is just over 110 dbw. BTW.. Pano will get even for the slobbering remark.... just wait... you will see!!

It is a state of the art HF driver... Part of the BM 740 series with mods to adapt it to Coaxial use.

Hope this is the kind of info you were looking for.

Slobber or not,

I would not change the HF driver. I would be very hard to do better - really.
Maybe you could, but you'd spend a lot of money and time trying. And that's for sure.

Even Cyndi Lauper would agree......

Oh okay, I was under the impression it was part of the current coaxial line that I found, but I guess it's something new. Where can I get some information on this? I assume the pricing will be a little high based on the pricing of the current models, but when I comes to big drivers, I tend to

I'm currently running 15" woofer/1" cd coaxial, so bigger = better mentality applies here

Thanks Danny,

They look very cool and knowing your work, I'm sure they sound even better. I am a big fan of paper cones and am glad to hear Tyler teaming up with you on the new speaker lines. They make great looking cabinets and their pricing is very good. Don't know much about their previous xover designs but I'm happy to hear you are doing the new ones.

Regarding the Xtatics, I'll give Mark an email if I get a large enough group. I am hoping to find someone local (AV123 has a great following in my area) because I'm not sure if I have the time toplan a big event. I would like to get the Xtatics, maybe Paul H's speakers, the new BESL's, and SP
Tech speakers, and maybe Gedlee's new speakers (I am thinking about building these this winter). What the heck, while I'm at it, maybe I can convince the Epik folks to let me try one of their subs (I'm about an hour away from their facility).

The biggest challenge is my work schedule. I'm doing a bit of traveling, incluidng some international, and I have a 3 year old who keeps me busy. I am overdue on a get-together and I hate to see the guys on the East Coast have all of the fun.

Cheers,

Jack

To bad no Hawthorne stuff was not there... Even the cheap ones sounds amazing with a little dampening. It is all about a little dampening.

Don't know if it's new or not - might be. This is the driver: http://www.p-audio.co.uk/products/db_product_1_6_bm-18cx38.htm
There seem to be some slightly different versions, JB can speak better to that issue. It sounds a LOT better than the FR plot might indicate. I tried to talk JB out of buying this driver - I was wrong....

I've heard the Hawthorns both with and without Augies. They do have a lot of promise, but IMO the crossover is all wrong. The crossover is paramount. Wish I had a pair to work on and try some crossover tricks.

Thanks for the driver link. For some rason I thought that was a 2" version. I may have to try a hand at these drivers.....

On the Hawthornes, for the cheaper performance grade Silver Iris (I assume this is what you listended to), there were two versions of the crossover. I wonder if you listened to the newer revised version or not. I own the Sterlings, and I do enjoy the sound. If you want to get your hands on the Sterling Silver Iris woofer and/or the Radian (he sells an ever so slightly modded version) without crossover, they are priced very well. A simple email will get you the quotes you need. A bulk of the costs actually lie in the Mundorf Silver/Oil (full caps, not bypasses) and 12ga Apha core based crossovers, and he will sell the pieces seperately. DMason did comment on the good work of the crossover in the Sterling Iris version he heard, so that might give you a more trusted set of ears than mine for an opinion on the crossover work of the newer line. Of course everyone hears differently, so.......

I would love to see what you can do to the crossovers should ever get one of the woofers and/or Radian tweeters to play with.

Russell Dawkins · « **Reply #35 on:** 20 Oct 2008, 02:38 am »

geez, panomaniac, I checked your link leading to the specs for the PAudio 18 incher. The plot for the bass section of the seems pretty optimistic in terms of the high frequency extension they claim for it!
It looks like it gets out to 20kHz, albeit erratically.

panomaniac · « **Reply #36 on:** 20 Oct 2008, 02:53 am »

It's all in the crossover.

The driver sounds a lot better than the plot looks, for sure. Crossover from cone to horn needs to happen at about 700Hz - acoustically. Electrically it's higher. Power response in the room is very good indeed. Image holds depth and width even far off axis.

The Silver Iris: Hard to beat the price! Great value I'd love to work with a pair to hear if the crossover can be improved. It could be killer. The 2 rigs I heard seriously lacked bass. The bass harmonics were there and would fool you after listening for awhile. But really, the bass fundamentals just were not there. The Augies (active) help beaucoup in that dept.

i've been living with thewm for a couple weeks now... thry'll need more than XO work to make them killer. I'm finding the cone self-noise makes them sound boxy. Habing then outside helped alot to...

panomaniac · « **Reply #38 on:** 20 Oct 2008, 04:42 am »

Well... killer for the price, anyway.

Yeah, I first heard them outside in your driveway. They did have a similar sound at the Puget Sound speaker contest.

New Orleans Crew member Henry logging in from the land down under. In Denver it was the New Orleans Crew's pleasure to slumber in OB umber in some RMAF rooms if only to get OB Reveling on a test cut of Cindy Lauper LIVE in the hotel room held by the Deacons of Dipole on the big 18s. Of all that was heard during the 3 days it was the Sunday mid-morning OB worship service where JBspeakerman and Panomaniac dispensed Cindy Lauper LIVE into their hotel room on the 18s. Crossover difficulty aside, at 10:30 AM the Deacons's abundant sonic purity from the mouth of the 18s got us on our feet along with the woman in the next room. Uplifted by OB's Promise, we were carried out the hotel and were returned back below sea level inside the levees of New Orleans and now cobbling our OB iterations. My OB Bent is 2 channel high efficiency, hopefully single point source with no subwoofer using only single ended amplification. Thanks for sharing, posting and keeping it pure from New Orleans Crew members.
