With a max SPL of 108 dB / 1W / 1 m and a frequency response of 20 - 20,000 Hz, the VOXATIV AC - Xp Fieldcoil-Driver is perfect for the mixing desk.

Those with a penchant of the old school may prefer the Krell KSA-50 as a companion amp. [50W]

In an article just today, Alan Sircom describes the work of Stuart McGill*, which caught our attention.
CEO of Walls of Sound and a brief transplant to Estonia, McGill describes wall mounted speaker drivers as having superior non-resonant and non-distoritive acoustic properties to those mounted in today's high-end loudspeaker cabinets.

While having studied under Bruce Pennycook and having a rough knowledge of fundamental acoustics, we do not understand how baseboard, drywall, and perhaps metal studs might have a superior non-resonant (and acoustic) properties of a B&W Matrix (wood), yet still a Magico Q-series (rigid, all-metal) enclosure.

Nay, we do not even understand how car manufacturer's may describe their frame-mounting bass (B&W) systems as high-end. Does that look non-resonant and designed for acoustic transmission to you?

We see nothing wrong with a baffle-mounted speaker such as the Voxactive Art Edition or the wonderful Jamo Loudspeaker R909, of which we first took notice regarding the technology's practical use, and can even agree with a concert-hall wall approach to a home listening environment. A room within a room, if you will.

The wall's of McGill's practice rooms certainly weren't, despite the description - a bit of a madhouse of musicians - soundproof, and neither are McGill's "Walls of Sound" sound-proof (non-resonant), we imagine.

Although it's clear that Stuart mounts his bass drivers in plywood cabinets, in the manner of an in-experienced home car enthusiast, judging by the look, despite the large "cabinet" volumes of home walls, we can not seem them as good dissipant storage for back-waves, indeed.

Nay, he even mentions brick as a good loudspeaker wall medium.

Listen to any ceiling mounted (in-ceiling) loudspeaker system, and you'll get an idea of the medium in description.

We are not to decry his methods, merely his marketing.

* We recorded a DAT recording with a trumpet player, Stuart Krauss, a student of McGill in Pollack Hall. The acoustics of the hall are just fine, but the street noise makes it non-worthwhile, for recording. The Chan Center in Vancouver offers better acoustics, and noise-isolation, by comparison - to us, this illustrates our non-interest in Stuart McGill's wall-mounting technology. We agree with his not wishing to see technology, but rather use it.
