Detailed Description Sub 15
Sub 15 extends low-frequency reproduction in compatible Optimal Audio installations. Its 15-inch LF driver operates in a plywood bass-reflex enclosure. The subwoofer handles 500 W AES and has a nominal impedance of 8 Ω.
The published response with the stated preset is 45–150 Hz within ±3 dB, reaching 40 Hz at −10 dB. Maximum output is specified at 135 dB peak in half-space. A steel grille protects the driver, and rubber feet support floor placement.
M8 fixing points provide for the supported suspension arrangements using appropriate hardware. Choose the amplifier and protection settings for the subwoofer load, then align crossover and level with the main speakers. A Zone controller adds source routing and browser-based daily control through WebApp.
