I am so jealous! still waiting for mine

[Nick77]

Thanks. The BG is exactly 1" larger, doent look good for swap.

Nick,

Very nice project! 

I couldn't help notice that you have some Onix Rockets in your picture.  Do you think the BG Tweeter would fit in that speaker?

Congrats and thanks,

Robert

Im glad I went ahead and took the plundge without hearing yours first. But I hope you get them real soon. I have one up and running with about 6hrs and continues to improve and amaze. Doing external xo's and ran out of wire on the second speaker.

pbrstreetgang,

The update on your OB 7's  is that they will be the first pair of veneered curved baffles that had all the driver seat dishing, cutouts ,drilling and roundovers done entirely on the CNC.

This used to be done in numerous machining operations before, each with a small degree of inconsistancy.

But that's all in the past now.  

Also, due to some issues we've discovered with using maple veneer, we've managed to locate some nicely figured sycamore and anegre veneer to pair with the sycamore baffles.

I just received the pics from my supplier today, I'll forward you the email with the pics over to you, and you can take a look and let me know which you prefer to pair along with the sycamore.

Cheers

Hum I take it those are the RS250.  Thanks for looking.

[Nick77]

I was able to finish these up over the weekend.



I did the crossover externally and might attach to the back of speaker to keep down the rats nest down that I already have going:(  Thinking of putting plexiglass as a cover.

[Danny Richie]

No wonder you needed extra wire.   

They look great though.

[Nick77]

Thanks Danny................

I am very happy with appearance, and dont really miss my commericial speakers at all. I am still putting some hrs on them but I am very pleased with the sound. They are very easy to listen to and I dont experience any fatique which I had occasionally with my other speakers. They are very resolving and demand a good source, but you are richly rewarded. I would say and agree with Bill that the bass is amazing. I have been listening to them mostly without a sub cause the bass is very clean and tight. I have the bass management system on my circut board but not employed yet during evaluation. I have a very large room and I think the rolloff might be ok without bass management. They are a step above my former speakers in almost every respect.
I would like to thank Danny for designing these and responding to all the emails.
Jason (Gitarretyp) helped me out with the XO's which were a little over my head, thanks Jason.
Appriciate all the other posts referring to their builds, thanks Tony, Denny and Bill.
I would encourage anyone thinking about this build to follow through, these are awesome. It was alot work from scratch but very rewarding. The flatpak would have been much eaisier.

I am still breaking in the OB-7's and enjoying them more and more. I have a question about speaker wire on a budget. I had tried a pair of anti-cables and although the detail was good I found them leaning toward bright. I have switched back to my Canair star quad wires but feel I have lost some detail. I am wondering what every one else has found? Any budget reccomendations?

[hoxuanduc]

For budget speaker wire, I found the Mapleshade Golden Helix to be excellent @ around $85.  Other choices include Dave Ellis' Vampire cable or Danny's internal speaker wire. If you want to go cheaper, braided Cat5 to taste is also good (remember to remove the jacket).

I didn't like the twisted 14awg or 18awg from inductors.  Didn't care for the Lowes' yardmaster stuff either.

[gitarretyp]

Congratulations on the build, keith . They look really nice.

As for the wise, I'd suggest using the same external as internal wiring.

[Danny Richie]

I have a 6 foot pair that I made from the same wire you are using internally. It's not pretty but it sounds really good.

If they are long enough for you and you want to try them out I'll send them to you. They won't cost much if you decide to keep them either.

Nick 77,

Just the passive components for your x-overs must costs you at least a few hundred dollars and you say they worth it!

cheers, nice speakers.

[Larry McConville]

Nick,

Your build looks really nice; what veneer species is this?

Regards,

Larry

Thanks Larry, I hope your project turns out well also. It is WALNUT CLARO QUARTER FIGURED from the veneer store.

Hey Nick,

 I have used various speaker cables with my OB-7 Deluxe including the same as I use for internal wiring (DH Labs). I have used Tributaries 14 awg copper, Micro Bearing filled cable from Star Sound Technologies, Acrolink 10 awg copper and so on. Right now I am going back and forth between a pair of Alpha Core (Goertz) copper foil and our new custom Silver/Gold foil cables.

 These speakers are very well capable of distinguishing between different cabling. I also tried a pair of Van Den Hul Hybrid cables and they lost quite a bit of sparkle/air up top. While the foil cables provide me with the best results, a decent quality 14 awg copper will allow these speakers to shine. Just wait till the speakers break in

You could do what I did and make your own out of standard multi-strand 16awg wire. I'm using 4 x 16awg per (+) and (-) of each speaker. Each side somes out to 10awg. For a 26' run, one side of the cable measures only 0.09 ohms on my HP 3435A MM at the spades! They are just a basic loose twist, but done by hand and took all of 5 hours to do (had to do it 4 times total). The cables are terminated with heavy duty spades and finished off with heat shrink. The bass is tighter, the treble is smoother and the overall sound is stronger sounding. Kind of hard to explain. These are the best sounding cables I've used to date, including Kimber 8TC, Space & Time, MIT, and several other overpriced cables.

Anyway, here's a few pics of the cables...

Keith, your inbox is full.

I had tried a pair of anti-cables and although the detail was good I found them leaning toward bright.

Could the brightness have been moderated by changing the value of the resistor in the tweeter crossover?

I'm still learning a LOT about cabling, and going to start experimenting with small gauge vs. large gauge.  Mapleshade says that 18 gauge solid copper with silver plating and PTFE insulation works very well, and if you can't get 18, 20 is better than 16.  Of course, the best in their opinion is their products, but those are along these lines of very fine conductors.  One reviewer from one of the high end review outfits says he prefers 16 gauge mil-spec PTFE insulated silver plated wire.

The posting above likes 10 gauge stranded.

We all know that perfect audio gear delivers exactly what the recording engineer put on the disc.  There is no perfect audio gear, so the goal is for the gear to add nothing to the sound and to take away the least.

I actually went back to the anti-cable's and probably will address the top end issue thru the crossover. It is mostly a room issue but due to waf issues room treatment is a no no. I like the solid cables tight bass and good detail.
