Features

Overview: The FOCAL Polyglass SB27V1 is a bass-reflex subwoofer enclosure with a 11" loaded FOCAL Polyglass 27V1 subwoofer and a flared port. This subwoofer enclosure provides high dynamic bass and high power handling in order to reach extremely high sound levels.

Bass Reflex Enclosure: The FOCAL SB27V1 features a bass-reflex enclosure with a front-firing flared port. The flared port is designed to reduce air noise. The enclosure is made of 5/8" MDF and features internal damping material for added rigidity and less vibration noise. The enclosure also features a removable cloth grille to protect the woofer's cone. In addition, the subwoofer enclosure utilizes nickel-plated spring-post terminals for easy connection of your speaker wire (up to 10AWG). The FOCAL SB27V1 presents a 4-ohm load at its speaker terminals. The subwoofer enclosure features four rubber feet and comes with a mounting kit which consists of two nylon straps, four metal brackets and eight screws to secure the enclosure in your vehicle.

11" Subwoofer (Polyglass 27V1): The FOCAL Polyglass SB27V1 features a loaded, front-firing 11" SVC 4-ohm FOCAL Polyglass 27V1 subwoofer. The FOCAL Polyglass 27V1 features an 11" polyglass cone woofer for a wide, dynamic frequency response of 36-500Hz that offers great bass and mid-bass sound. The uniform deposit of hollow-glass microballs over the entire cellulose pulp cone greatly increases its rigidity without adding significant weight, so you get a woofer that is durable, yet efficient, and sounds great. The woofer also features a NBR (Nitrile Butyl Rubber) surround for long excursion, deep bass, and added durability to promote long life. The Polyglass 27V1 woofer features a 4 layer, 2.0" diameter, 4-ohm, aluminum voice-coil former for higher power handling capabilities up to 250 watt (RMS) and 500 watt (Peak). The Polyglass 27V1's Louvered Cooling System is a self-regulated ventilation system which increases air cooling, prevents heat build-up, and provides optimized reliability with performance consistency. The Polyglass 27V1 woofer features a120mm (4.75"), 25mm (1") thick ferrite magnet for higher sensitivity up to 90dB (2.83V/1m). In addition, the FOCAL Polyglass 27V1 features a die-cast Zamak chassis which is a rigid, non-magnetic, and non-resonant frame that provides a strong, reliable structure for the woofer.
