Yorkville Sound

Colossally powerful (136dB max. SPL) and able to shake the floor right down to 35Hz, the LS1208 is virtually without equal.

Yorkville's two year investigation into the optimization of high output low frequency sound has yielded the LS1208's "basspipe" subwoofer configuration. The "basspipe" is a multiple flare horn, connected to an organ-like pipe, slowly flaring to the mouth. The bandwidth is narrowed, optimized to a specific range in the lower registers. Outdoor measurements show very smooth, very high output in the 35Hz to 200Hz range. This is the highest efficiency that we have ever seen for a single 18" driver enclosure, especially with a gross volume of only 22 cubic feet. In addition, a significant gain is achieved when using two units side by side as the mouth nears maximum acoustic load. Max SPL's at a window-rattling 139dB are possible from the coupled pair.

Additional Yorkville research has led to the development of an 18-inch driver with significantly higher power handling than any other speaker that they currently use, making the LS1208 one of the most reliable high-output subwoofers available at any price.

Suitable for touring or fixed installations, the LS1208 is constructed of 15mm 11-ply Baltic Birch with heavy internal bracing for reduced resonance and better durability. The enclosure is covered in durable black Ozite carpet. An optional finish of black Ultrathane paint (LS1208B) is also available. Additionally, the Speakon connectors feature a configuration switch that allows instant reversal of Speakon jack pinouts for easy sub/full-range biamping using optional four-conductor Speakon cables.

The LS1208 further includes tilt-back wheels and top/rear-mounted corner handles, plus side handles for better maneuverability and stacking.
