    We improved the lower end of our popular dual in-wall subwoofer. 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.

    Amplifier Suggestions
    Because this is a passive speaker, it will require a subwoofer amplifier to power it. An ideal match to this subwoofer is our OSD SMP500 dedicated subwoofer amplifier that 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).

    Jody OLeary • 11/01/2021, 5:11:48 PM I already bought 1 IWS-88 and might by a second. Can 1 Sub amp power both of them? If so which amp is best to accomplish task?

    Hi Jody: The IWS88 is rated at 4-ohms so you limited to driving just one IWS88 with our dedicated Subwoofer Amplifier, most of which are 4-ohm rated as well. The minimum Sub amplifer for this speaker would be our SMP200 rated at 200 watts RMS at 4-ohms with peaks at 400 watts. If you want to add a second IWS88 you will need a second sub amp as well. Both the SMP300 or SAM300 will work as well. TIML/11-8-2021
