SKU: KIT-SMP500-IWS88 Dual 8" In-Wall Subwoofer w/ Reinforced Back Bridge + 400W RMS Class D DSP Subwoofer Amplifier
By adding a strong reinforced back plate to stiff the structure of the subwoofer, we make it to sound deeper and clean. A subwoofer is designed to reproduce the lowest of audible frequencies and will give you that spine-tingling rumble effect that takes you out of reality and into the plot. With dual 8" Injected polypropylene woofers, bigger magnets and 350 Watts of power handling, the IWS-88 in-wall subwoofer performs excellently for home theater surround sound applications as well as for listening to music. Like all OSD Audio speakers, the IWS-88 includes a dog-ear bracket system that mounts securely to the sheet-rock after the cut-out hole has been made and the speaker has been dropped into the hole. The grille is paintable to match your room decor and we even include a cutout template that doubles as a paint shield. You'll experience thunderous, room-filling bass without filling up floor space.
Because this is a passive speaker, it will require a subwoofer amplifier to power it, so we have paired it up with our SMP500, which features 400W RMS @ 4 ohms, Variable High Cut Filter 30Hz-150Hz; front panel Knob, and Choice of Signal Level Input or LFE (Low-Frequency Effects).
You'll experience deep, rich and crisp bass while watching your favorite movies, especially action and adventure flicks. A big bang for the buck, features include a front-mounted power meter, back panel adjustable gain and volume control limiter to protect the woofers as well as low-level and high-level pass-through input/outputs to cover newer and old school sound systems. Combining the best qualities of both class A and B amp technologies, distortion is low while efficiency is high, and the SMP500DSP Mono Amp also includes a variable high cut filter that routes higher frequencies to main speakers. This allows subs to concentrate on the low-frequency sound effects for which they are designed and keeps low bass away from your surround speakers for much cleaner highs and midrange.
