General Information In-Wall Thin Bezel Subwoofer, perfect for retro-fit! Powerful in-wall bass that hides from view The IW-28 SUB is an in-wall subwoofer that uses dual heavy-duty 8" woofers to deliver rich, vibrant bass to custom-installed audio systems. Boasting amazing hookup flexibility, the 28 SUB can either be used passively, driven directly off the receiver's front Left/Right speaker outputs by utilizing the 28 SUB's on-board low-pass crossover, OR it can be driven actively by using a power amplifier such as our SA-200 connected to the receiver's 'sub out' jack. The 28 SUB's on-board low-pass crossover is then switched to 'off,' and the crossover functions and bass level duties are handled by the system electronics, as with any powered subwoofer. Technical Information Minimum Frequency Response: 38 Hz Maximum Frequency Response: 200 Hz Impedance: 8 Ohm Sensitivity: 89 dB Physical Characteristics Form Factor: In-wall Weight (Approximate): 20 lb Miscellaneous Environmental Certification: WEEE
