The Digital Sound Projector speakers were designed to look snazzy hung on a wall under a flat-screen TV, so the Yamaha YST-FSW100 picks up on the speaker's styling cues and uses a trim, 6.25-inch-deep cabinet, designed to lay flat against the wall. The curved front grille adds a bit of style to the design, and the YST-FSW100 is available in silver or black finishes. It's 15.75 inches wide and 14.5 high, and it weighs a solid 19.8 pounds.
The sub sports a 6.5-inch woofer, a 75-watt amplifier, and a half-pipe port that extends deep bass response while minimizing extraneous noise. The volume control is conveniently located on the sub's top panel. Connectivity is limited to a line-level RCA input.
The Thin Red Line DVD demonstrated the Yamaha YST-FSW100's home-theater prowess. There's a scene early in the film where Sean Penn is giving advice to a young soldier in the belly of a transport ship. Most pint-size subs render the low rumbling mechanical sound of the ship's engine as undifferentiated boom, but the Yamaha transmitted each shudder of the mighty power plant. The jungle battle sequences later in the film had plenty of visceral impact. Turning to music, we popped in one of Shaggy's rap-reggae CDs, which are loaded with bombastic bass rhythms. This little sub pumped out the deep beats like a champ, as long as we didn't push the volume too hard.
At the end of the day, the Yamaha YST-FSW100 was designed for one thing--to complement the Yamaha Digital Sound Projector--and it performs that function admirably. In terms of design and performance, the YST-FSW100 is the ideal partner for Yamaha's YSP-1, YSP-800, or YSP-1000.
