ahh....one of my favorite threads awakens again..those are sweet looking, very graceful..I'd love to hear them.carbon fiber is super strong, but so very brittle..i suppose speakers aren't built for impact resistance anyway...very nice!

In my past life, my company made "structural" carbon fiber products (race bike components), and I learned that most of the items we see in the public are not of a structural quality, in part because this level requires many layers of carbon fiber, very little resin. It is much cheaper to use one layer of carbon fiber, and a lot of resin. As for these speakers, they are VERY expensive, so it would be sad to tip them over accidentally and damage them.
 
The specs on those Yamaha panel speakers can't be accurrate... Maybe it's in that range -15 db. Regardless, I'm intrigued by them. :D

YAMAHA AST-F100 Speakers (aka. YST-SF50)

The Yamaha AST-F100 was sold in the USA as the YST-SF50
- stand or wall mount (correct)
- 25Hz-30kHz (correct)
- 112dB SPL/1kHz (cannot confirm, not in my literature)

I have an old 1980's full line flyer that shows this speaker, but only two of the above specs can be verified. They were part of Yamaha's "special" YST line, so to sound good (read: be able to perform to spec), a Yamaha Active Servo Processing cartridge was included and needed to be used with the amplifier driving them. I have a Yamaha DSP-A700 unit that has the port to plug-in this cartridge, but I have never seen this on any other amp before, so actual applications for this speaker is limited. In any case, all of the YST speakers have better-than-expected specs due to this technology.
 
How about a pair of Sony SS-9500 speakers?

The pic is not mine, but I still have a very nice set of these in my living room.

This is a great thread! I wish I could listen to all of them to see (hear?) if some sound as good as they look. Two that I have had the pleasure to listen to some twenty years ago where:

Infinity IRS - The first time I ran across these where at a high-end hi-fi show held at a hotel in the San Francisco Bay Area. I was walking through a hallway when I felt (not heard) a strange compression-like feeling in my chest and the floor seemed to be moving almost like an earthquake. It turned out to be the IRSs' being demoed in another part of the hotel. I got a chance to really listen/feel them later in the day and was totally blown away (literally and figuratively). They were driven by 1500W amps (per side) and the source was a studio tapedeck playing 1" wide master tape. Little known fact: the wood that is used in the construction of each set of IRS speakers comes from the same log to make sure the color and grain match. Price at that time was $50,000 a pair. BTW: The room that they're shown in in the photo is WAY too small!

MBL 101e Radial Strahler - These were/are the best speakers I've ever listened to - PERIOD. Nothing I've listened to in the past 20 years even come close to these things. Placement and setup is a PITA, but get it right and you'll be rewarded with the best sound stage and sonic window you'll ever experience. Close your eyes and you can swear the musicians are right there in front of you. Individual instruments/voices can be easily picked out in virtual space. And it isn't just the imaging that's remarkable, the sound "texture", openess and dynamics is amazingly real, too. While the bass isn't "subwoofer" deep, it's perfect for anything short of reggie or hard rock. Walk around the room with your eyes closed (try not to bump into anything) and the sound stage remains intact. The speakers literally disappear once the music starts; you can not pinpoint their physical location even with your eyes open. These are true omnidirectional speakers. The best virtual reality for your ears. It really is hard to discribe in mere words how these sound other than "sonic orgasm". You owe it to yourself to give them a listen if the chance should ever arise. I'd sell my left you-know-what to own a pair of these. Back then they were a breath-taking $30,000 a pair. Current price is $60,000.

Be sure and buy a strobe light to counteract the effect... :D

not quite as unique

while there not as unique as most of these my design acoustics d-12s were pretty hot for there day-and they still rock:scratch2:ok now i need some of everyones expert advice-i was given another set of d-12s in excellent shape cabinet wise but all the insides were gone-so my brain says lets go crazy-i want to put 10 8in drivers in them and leave 2 ports-i want something that will handle lots of power driving metal music to the limt??????:rockon:
 
D 12s are neat enough and rare enough that I hope you pass on the carcasses to someone who wants to restore them. Your idea sounds interesting, but you'd have to make sure that you use drivers that will work in that unusual setup -- you'd need to use some combination of series and parallel connections unless you come up with a bunch of very odd impedance drivers, and they would need to work well in the enclosure volume. And gettting the ports the right length might be more difficult than expected, since you would be starting with an odd setup.
But lucky you -- potentially two sets of D 12s! Most of us have none. And aren't happy about it either.
