General:
This 800 series high-pass alignment filter is designed to work with the Bowers & Wilkins Matrix 803 speakers. This filter is designed to selectively attenuate bass frequencies for these specific speakers, and will also increase the bass response on other 800 series speakers.

For instance it can be added between the "Pre Outs" and "Main In" on your amplifier, or via an available tape loop to modify the incoming signal. 

This piece is in great condition and will come with its matching power supply.
