LS1208

Overview

A two year investigation into the optimization of high output low

frequency sound has yielded the LS1208 "basspipe" subwoofer

system. 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.

Additional research has developed a woofer with significantly higher

power handling than any other speaker that we currently use, making

the LS1208 one of the highest output subwoofers available at any

price. Performance, packaging, and overall value make the LS1208 a

benchmark.

Suitable for touring or fixed installations, the cabinets are constructed

of 15mm 11-ply Baltic Birch with heavy internal bracing for reduced

resonance and better durability. The enclosure is covered in a black

carpet covering and incorporates metal corner protectors, rugged

curved anti-resonant metal grilles, and 1/4" or Speakon™ input

connectors. An optional finish of black ultrathane paint (LS1208B) is

also available. Additionally, the Speakon™ connectors feature a

configuration switch which allows instant reversal of Speakon™ jack

pinouts for easy single wire hook-up using optional four wire

Speakon™ cables. The LS1208 includes tilt-back wheels and top/rear

mounted corner handles for better maneuverability and stacking.
