The BIG decision...
« on: 19 Dec 2006, 03:34 am »
I've got money to do a killer DIY pair, and I'm down to a decision point, and that is:  LS-types or OB types.  After Danny's original Alpha LS pair, and what I'm reading about the new LS series, I'd probably pull the trigger on an LS.   BUT, earlier this year, I sliced and diced the MDF for a local customer who had another designer (okay, it was Rick Craig) design a high-end OB speaker;  open baffle MTM on top, attached to a bass bin.  M's were Accuton C82's, tweet was BG Neo 3, woof for the bass cab was Seas W22EX.  When I heard them, was I impressed by:
dynamics?  nope
extreme LR world-class soundstage?  nope
extreme depth of soundstage?  nope
neutrality?  YES, LIKE NEVER BEFORE!!!!  OB could convert me to a "Chicks singing" fan ;-)

What am I saying here?  Danny knows that I've been on a DIY quest for speakers that can accurately reproduce a LARGE ensemble and its incredible dynamics.  I play in the Austin Symphonic Band, a wind and percussion world-class ensemble of 85 musicians.  As yet, I haven't found a speaker that can reproduce our sound at concert volume levels without intrusive distortion.  Closest was Danny's Alpha LS.

But, I am in confession mode here and I admit that the El Ultimo speaker for me would be an OB design with enough drivers to deliver DYNAMICS.  So, Danny, I throw down the gauntlet, and suggest a name for El Ultimo:  OBLA-D!  An homage to the Beetles? ("Obla-Dee, Obla-Dah, Life Goes On...").  No:  Open Baffle Line Array - D (Danny).

Go for it, Danny!

Yup, I have 2 of Danny's designs. They are very different. But are both very neutral. I couldn't live without that in a speaker. I don't want anything hyped up. Period.

Actually, I think Danny's nickname is Mr. Neutral. Or is it his middlename? Or did I just start that rumor? :P :wink:

Cheers

Hank, you need to make the drive up to Forth Worth and listen to the LS-6's at Art's house.  Art has assembled a system that is among the best I have ever heard. It will be well worth your trip, and will answer your questions.

And yes there is a big open baffle line source on the drawing board that I promise will be worked on this year. Some aspects are already in motion.

Hank, you are welcome up anytime we can arrange it to hear the prototype 6's in my humble system.  I had about 8 guys over yesterday (I'm working on compiling impressions from the session and will post them tomorrow latest) and still have 4 or 5 others wanting to arrange something around the holidays or shortly after.  Shoot me an e-mail and let's get you up here if you can swing it! 

As an aside, I like the OBLA-D! as a name, and am ready for them whenever Danny is, I'll be getting 9's to tide me over until that day comes........

Wow, Danny, you'd better get busy - only 12 days left.   :icon_surprised:

OBLA-D is on the way  :thumb:

How about one of the long B-G's instead of several small ones stacked?

Art:  thanks for the invitation.  My daughter and her husband are both ICU RN's at Harris Methodist hospital, so it won't be too long before I visit them - maybe February.  I'll be in touch.

Nope, they are not at the same performance level.

Danny,

Can you expand a bit on your feelings why the larger BG is not up to a set of the smaller ones?

Thanks,

Bryan

The larger ones have very low sensitivity and are not much on power handling. The top end is a bit soft or rolled off. They are not as fast (have a longer spectral decay) and just do not sound as good as the Neo's.
