Open Baffles at RMAF-07
Default Open Baffles at RMAF-07

Of the few very good systems I heard at RMAF-07, three were open baffle. (There were a lot of good systems, few were very good)

So here is a thread to discuss those 3 designs and learn from them for our own projects.

The 3 systems were:

Nelson Pass - Lowther
Tall mid size baffle
1 Lowther full range,
2x10" Seas woofers.
Active filtering.


Lyngdorf
The DP-1 .
Slim double curve baffle
6.5" Magnesium mid/woofer
Revelator tweeter. 10" Bass units against the wall.


Manzanita 12"
A friend who brought 2 OB systems just for fun.
The small system put 90% of the speakers at RMAF to shame (but not the 2 above).
2 way passive with
Peerless SLS 830669 - 12" Woofer
Vifa D27TG45 1" dome tweeter.
6 element Passive crossover.
About $200 per side, all drivers, parts and wood included!


I will try to assemble more details on these 2 systems. Please feel free to contribute. There is a lot to be learned from these 3 systems.

I saw a couple that might qualify:

The Bastanis, which are labeled as OB and have some
kind of grill cloth in the rear.

Hmmm. I was figuring somebody would show up with a pair of low compromise high efficiency dipoles. It's really not that difficult!

Was there any interesting full range, fully horn loaded systems?

I made the mistake of reading the Stereophile "blog" of the RMAF. I must say that I was embarrassed. There was nothing technical in the descriptions...only pricing that would make a subprime lender blush...and I thought that this industry had lost its collective mind ten years ago.

Boy, was I wrong.

Barnum said that there was a sucker born every minute; that was when the U.S. had ~80 million people. As we approach 300 million, I take it that Barnum's timeframe has shrunk somewhat.

Thanks Nelson.

I didn't get a chance to hear a lot of rooms, too busy in our own.

Do you want to include any of these in the "what can we learn from studying these designs" list?

Did you miss the Emerald Physics CS2 on your list?

These guys claim that it was there:

I also claim that the Emerald Physics CS2 was there. I'm one of their dealers, and visited the room they were in.
