BX2 is a bass frequency extension technology that provides perceived bass frequency response below the low frequency cut off in an audio system.
BX2 uses the principle of the missing fundamental, which creates the sensation of low frequencies by generating a carefully calculated series of harmonics designed to simulate the auditory experience in the human ear caused by the missing fundamental pitch.
These harmonics extend the perceived frequency response up to 1.5 octaves below the speaker cutoff frequency (f3) without perceived distortion, increased peak power consumption or peak speaker excursion.
BX2 technology allows the system user to experience dramatically improved levels of system performance, sound quality and improved low frequency
Increasing low frequency output and performance without causing the speakers to perform outside their physical design limitations.
Decreasing power consumption during low frequency reproduction up to 75%.
Allows small format speakers to reproduce low frequencies traditionally designed for
I have this listed on eBay for $225 with free shipping. Might be willing to compromise just a tad if reasonable offer.
