The Future of Bass: Dual Horn Loaded Subwoofers. By thinking inside the box, LCH Audio delivers breakthrough acoustically amplified innovations. Using a concealed driver that fires into an acoustic engine room conditions the output to the dual horns. As a result, LCH Audio provides a design like no other which makes a speaker like an instrument. The LCH Compression Chamber contains a plurality of nested shells for sound that each acoustically amplify successively lower octaves just like larger instruments produce lower tones. LCH Audio is patented in the U.S. with patents pending in UK, EU, China, India, Singapore, and Hong Kong. LCH speakers are entirely engineered and manufactured in Houston, TX. Today the Model "Eleven" MSRP is $3850 each with a pair at only $6995.
