OSD IWS88Dual 8" In Wall Subwoofer 350W, Injected Woofers Back Bridge Plate
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).

Can I power this subwhoofer duel 8" IWS-88 with a receiver such as the Yamaha 7.2 RX V575, I would like to avoid spending 299 on the SMP250 and having more equipment added my bookshelf. If not, is there another 7.2 receiver that would work at a reasonable price please let me know. I have in wall OSD speakers in place and would like to add this in wall subwhoofer to complete my system.

Hi Tim,
As long as you are using a 5.1 or 7.2 Receiver, they have enough power for the subwoofer. A receiver would have a Subwoofer channel with a built in crossover to separate the highs and lows frequencies, A 2 channel Amplifier would not have the crossover to do this.

Tim from Chicago again. ( See question from last week)
I asked the question about using IWS-88 and powering it with the Yamaha RX-V 575 7.2.
1. Yamaha's connection for the subwoofer calls for a audio pin cable. How do I convert the speaker wire I connected at IWS-88 and pulled to the RX-V575 to a audio pin cable?
2. On page 4 of the Yamaha's directions, they say to use a subwoofer with a built-in amplifier. Per the question I asked last week, the answer was the RX-V575 has enough power for the IWS-88. HELP!!!!!!

Hi Tim,
You would need a subwoofer amplifier in order to power the in-wall subs. Our SMP60 can power the IWS8, and our SMP250 will power the IWS-88 and IWS10. Unfortunately we are out-of-stock on both amps for another month or so, but you can't really run these subs with a stereo amp/receiver such as your Yamaha. The reason being that these subs don't have crossovers to filter out the highs, so you need an amp that does that for them.

I have purchased 5 in wall OSD speakers so far. Very Happy. I want to add this to my system -by plugging this passive subwoofer into one of the dedicated sub outs - of my 7.2 receiver. What cable to I need? The back of my Sony receiver has an RCA available for this sub. Running an RCA male to exposed speaker wire seems like a nightmare. Please advise -and I will buy. Thanks

Hi Jon,
You will need a Subwoofer Amplifier to power the IWS-88. The Sub Amp will have a built in crossover which will separate the high and low frequencies and will only send the low frequencies to the amplifier. You will use a subwoofer cable to run from the receiver to the Sub amp. I suggest looking at the SMP250.

I am planning to make a 7.1 system considering: MKIW550LCR for the central Chanel, OSD-MKW-850 for the LR front Chanel and I have a doubt whichr rear surround I need to use MK670 or MK690TT? Another doubt is which subwoofer I need to use IWS-88 or IWS-10? please help me to define my system. Thank you.

Hello again Max,
You can use either speaker for the back, but if the back speakers are not somewhat above the sitting area, you could use the MK670 for the angle. For the sub, I personally recommend a powered floor standing sub such as the PS10 or PS12, because the in-wall subs need a subwoofer amplifier.
