The12 SUB PRO PASSIVE SEALED SH with its sealed cabinet concept offers a rock-solid bass sound from the smallest of dimensions, easily integrable in restricted installation situations. With its shallow depth of 210 mm (8.27”) and exceptional 12” woofer, it can deliver the kind of tight, punchy bass and impressive dynamics that many would like from their modest home theaters or media rooms, all while tucked away in out-of-the-way locations.
The12 SUB PRO PASSIVE SEALED SH shares the same core design advantages the entire range of ASCENDO subwoofers feature - extremely low distortion to reproduce the finest details with the highest dynamic range to meet the content transients without compression, but perhaps more importantly, a linear response from bottom to top to allow for exceptional integration with the main and surround channels.
12" forward-firing, advanced carbon nomex pulp mix cones, neodymium motor with 4” ultra-high-temperature voice-coil and triple shorting rings.
20 mm excursion each direction (40 mm linear), voice coil remaining in homogeneous magnetic field, linear and lowest distortion
