Detailed Description Sub 10
Sub 10 is a passive 10-inch subwoofer designed to extend the bass response of installed loudspeaker systems. It handles 250 W AES into a nominal 8 Ω load. With the specified preset, its response is 50–150 Hz within ±3 dB and reaches 42 Hz at −10 dB.

The low-profile plywood enclosure can be positioned beneath seating or in spaces where cabinet height is restricted. A perforated steel grille protects the driver. Rubber feet and M8 inserts provide the installation options described in the user guide, with an optional Sub Bracket available.
Match the amplifier and processing preset to the subwoofer, then set the system crossover and level for the companion loudspeakers. Zone and WebApp provide routing and everyday control where a Zone controller forms part of the installation.
