    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).

    Johan • 12/17/2019, 2:17:43 PM Why do the IWS-88 subwoofer not have the same white color as the other OSD speakers I have bought?
    Customer Service • 12/17/2019, 2:17:43 PM
    Hi Johan, The speakers in the same series will have the same color but not all of our speakers are made at the same location. Shades of white can vary. All OSD in-wall and in-ceiling speaker grilles and frames can be painted to match your room's dcor. CL/MA 1634
    gary • 12/17/2019, 2:17:43 PM I was thinking about purchasing this speaker. It says cinema meaning home theater. Is it also good for music?

    Hi Gary, The IWS88 in-wall subwoofer is a great balance between performance and price. This subwoofer performs excellently for home theater surround sound applications as well as for listening to music. CL/MA 1647
    ERIC • 12/17/2019, 2:17:43 PM DO YOU NEED A POWERED SUB TO DRIVE THIS SUB OR CAN YOU USE IT PASSIVE. WHAT IS THE CONNECTION? RCA? ANY SPEC SHEETS AVAILABLE
    Customer Service • 12/17/2019, 2:17:43 PM
    Hi Eric, This in-wall subwoofer is passive and requires a subwoofer amplifier, such as our SMP250, to power it. The connection from the subwoofer to the amp is speaker cable. CL/MA 1845
    mike padilla • 12/17/2019, 2:17:43 PM what is the optomal location for this speaker, front or rear? and what is the ideal height? can i install at 7' high
    Customer Service • 12/17/2019, 2:17:43 PM
    Hi Mike: That is a tough question. Probably the best location is the one that is most accessible for your wiring from your Sub-woofer Amplifier. And you also need to take into consideration the idea of mounting the speaker in the wall with an internal enclosure to make sure all the sound is focused into the room and not bleeding out the back. You need to pick an area where you can build the enclosure. Also if you budget allows it think about adding a second IWS-88 to be mounted opposite of the first , so front and back as an example. There is a reason the Receiver companies are now promoting 7.2 systems which call for two Sub-woofers. The problem with just one sub is that with the large sign waves from the sub there is a tendency for dead spots in the smaller room. So adding a second Sub-woofer is recommended to fill in the gaps. The advantage of a stand alone external Sub-woofer is you can experiment with the location moving it around the room to find the optimum spot. I hope that helps TS-2281
    Gary • 12/17/2019, 2:17:43 PM Hello, I have 7.1 Pioneer amp in my kitchen . I run it in stereo on two in ceiling speakers. Can I run these subs powered from my available empty channels on the receiver directly to each of these speakers ?I have already prewired in wall with 2 runs of speaker cable to same location. Thank You

    Hi Gary, I would suggest getting a Sub amp to power the IWS88s as a 7.1 receiver would not have enough power for both subs. Check out the SMP250. That would be enough for both of those. CS 2537
