Bass Alignment Filter for 800 Matrix

About the Bass Alignment Filter for 800 Matrix

The Anodyne Group Bass Alignment Filter for the 800 Matrix Series is a specialized active equalizer integral to the design of B&W Matrix 800 series speakers. It precisely boosts bass frequencies while removing subsonic frequencies that cause distortion, effectively improving bass extension and sensitivity without compromising overall sound quality. The filter uses discrete circuitry with transistors rather than integrated operational amplifiers, providing a very flat frequency response with a maximum boost of around +6 dB near 37 Hz and a steep roll-off below that. This filter is essential for achieving the full designed performance of the Matrix 800 series, as the speakers' specifications assume its use. It is typically placed between the preamplifier and power amplifier and is supplied with both single-ended and balanced connectors. The filter is known for its very low distortion and precise bass alignment, contributing to the speaker's renowned sound quality.
