Do the boxes underneath perform an acoustic function, or just to get them off the floor??

Do the boxes underneath perform an acoustic function, or just to get them off the floor??
The mid-bass driver acoustically loads the bottom box through an acoustic baffle. The idea is that the mid-bass driver acoustically "sees" a much larger box to give it more extension, while the small box that actually holds the driver can be very rigid to control resonance. All three boxes mount on a steel frame and are separate from each other, hence the name Separate Box Loudspeaker.
Very fussy to set up, and extremely revealing/demanding of the components driving them. When done properly, an absolutely astoundingly accurate and good sounding speaker. In the wrong setup - don't bother.

They also had a big brother, the DBL. Officially the Decoupled Box Loudspeaker, affectionately known as the Damn Big Loudspeaker.

Thanks. So it's not a typical bass-reflex set-up, but rather an "infinate" baffle.
Mine use the rear motion of the cone, but the baffle inside delays the wave one half cycle before exiting at the bottom.
Much more efficient, requiring less power to drive them properly.
I have three main systems that I use each for different functions:
Main: Onkyo HT-S790
- Pre-BluRay/Master Audio/HDMI. 7.1 system that sounds fantastic. Plenty of optical ins and a S/PDIF in so HDMI really isn't an issue. The Mac and iOS devices Airplay to it through the optical port on the Airport Express.
Basement System: Boston Acoustics BA790 2.1 System.
- 10 years old but still sounds amazing. When it was new it was only $90 and easily sounds as good as a Klipsch 2.1 system. Massive bang for your buck back then. Digital S/PDIF in.
Headphones: Sony MDR-7506's
- I like them for their flat response and they can be EQ'd the heck out of for coloration. +12dB results in no distortion. Still love 'em even though I need to replace the cord and pads (which can still be had).

I think that's essentially correct, although I don't remember Naim calling it an infinite baffle.
Surprisingly deep bass from a relatively small speaker - as the one link said, they're not tiny, but they are remarkably unobtrusive.
The DBL - now that's a whole other ball of wax. I had the chance to hear them actively driven in a full-tilt Naim system, and it was far and away the best sounding system I've ever heard. Of course, it would have cost about $150K or so . . .
A pair of these. They are about 45 this year. Don't sound a day over 16.
Electrovoice Marquis bass-reflex, with 12's and horns.
While I'm no fan of the finish, they look awesome. Old, good audio equipment doesn't go bad if you treat it correctly. ^__^
That kind of reminds me of Carlsson type speakers, of which I am incidentally currently working on building a few of. Are they in some way related?
A set of JBL Creatures for when it's too late and a pair of Bowers and Wilkins DM603 driven from a Yamaha AV Amp for the other times 
Not that I'm aware of - the SBL was originally released in 1986 and had been under development for some time before that. Naim in many respects was the Apple of hifi through the 90s. What Naim lacked was the hifi equivalent of the iPod.
You will be pleased. Just note its for close listening, it can do well for a room party but not a house party.Nice, very pleasing to the critical eye. Mine.
I hope the sound matches the art?
For sub placement, I just have mines off to the sides. I don't have too much space in my room as is (I'm actually in a guest room).
Okay. The Carlsson ones are older then, but maybe some uncredited inspiration has been going on.
Cool stuff anyway. I love unconventional audio gear.
Not computer related I have a pair of B&W 603 series 3 driven by a 45 watt per channel integrated tube amp. My source is a turntable and CD player. It's in a dedicated listening room..
The speakers that I have hooked up to my computer are pretty funny. I have two Bose 100 fronts, two Radio Shack Realistic rears, another larger Radio Shack Realistic double midrange/subwoofer speaker as a center and I have a large, self-powered subwoofer under my desk. The whole system is powered by an old Pioneer reciever next to my computer. It looks pretty gheto, but it has really, REALLY good sound.
i have these. has more than one input, 3.5mm out, ipod dock, usb input.
also bought a stand for them.
I know there is a lot of anti-Bose people out there....but I enjoy mine and the sound is quite good to me
same ones here...for about 5 years now. they won't quit!!1

ok krafty...that is a sick setup. im a simple and clean person, and love that. where did you find that desk?!
