Sonance’s Bandpass Subwoofer System By RS Staff Published: October 14, 2008 ⋅ Updated: April 15, 2019 The Sonance Architectural Series is introducing a new Bandpass Subwoofer System at CES, which is sonically designed for use with the Sonance Architectural Series in-wall and in-ceiling loudspeaker systems. The Sonance Architectural Series BPS-1 Bandpass Subwoofer System is designed to add deep, powerful bass impact while the enclosure remains completely hidden from view. It delivers its bass energy through a Sonance Architectural Series Finish Component that is a visually discrete complement to the surrounding architecture space. The trimless and truly flush-mount installation mounts the plane of the subwoofer grille perfectly aligned with the plane of the wall or ceiling. Adaptor Baffles are available which allow the BPS-1 Subwoofer to be used with any size round or square Architectural Series Panel Bracket (even 4-inch) to match other AS speakers in the audio system and any separately available Architectural Series Finish Component: metal (with or without trim) or cloth (with or without trim). Sonance recommends the use of the Sonamp A150 power amplifier which delivers 150 watts of power RMS and provides flexible connections.
