Atlantic Technology introduced the new T-90 system, which will be available in April or May. The system will cost aproximately $1,700 and places just above the T-70 in their product line. The T-90 satellites feature a newly designed 5¼" woofer with a Titanium Coated Molded Graphite cone. The tweeter is the same 1" fabric tweeter used in the T-70. The center channel has two TCMG drivers and the same tweeter and comes with a tilting base. The surrounds use a single woofer/midrange driver with a pair of side firing, phase-reversed ¾" Mylar dome tweeters. The subwoofer is a sealed enclosure design, and has a Class G discrete 150 watt amplifier and a 12" cellulose composite pulp diaphram.

The photograph to the right shows the prototype system, from left to right: surround, center (top), sub (bottom) and L/R. The surrounds will change slightly prior to production so that they fit a little closer to the wall.

Alongside the Atlantic Technology system, its designer, Vance Dickason, who also designed most of the AT speakers, including the System 370THX that I use at home. I should also point out that Vance is the author of 'The Loudspeaker Design Cookbook', now in its sixth edition and available in seven languages.

Look ma, no amps! Although active loudspeakers are common in the professional audio world, they're relatively rare in home theater systems. Miller & Kriesel Sound makes an impressive case for them with the release of their self-powered S-150PTHX ($2,199 each), a consumer version of the company's successful MPS-2510P studio monitors. With their built-in 180watt amplifiers, the S-150PTHX filled the M&K booth with spectacular dynamics and resolution on a variety of music and film sources. []
