    In-wall subs are a great way to experience low frequencies effects without filling up floor space. An excellent in-wall subwoofer at an excellent price, the IWS8 is an 8" passive sub with power handling up to 150 Watts. Installation is easy with our dog-ear bracket system that mounts to the sheet-rock after the cut-out hole has been made. The grille is also paintable to match your room decor and we include a cutout template that doubles as a paint shield. 

    Amplifier Suggestions
    OSD Audio in-wall subs are passive devices, meaning they do not include a built-in amplifier like you would find in our active "box" subs. You will have to provide additional power, specifically a subwoofer amplifier, to drive it. We recommend our SMP200 dedicated subwoofer amplifier that features 120 watts (mono) and front panel controls, phase switch, frequency control knob (35 Hz to 160 Hz) and volume control.

    Daniel • 12/17/2019, 2:17:43 PM Can 10 gauge speaker wires work with this? I plan to buy long rolls of 10 gauge wires for the ICE670s (150ft runs to the AV receiver) .... and would like to utilize the same wire if possible. Someone mentioned anything larger than 14 gauge may not work in the IWS-8 or IWS-10?
    Customer Service • 12/17/2019, 2:17:43 PM
    Hi Daniel, Cable that is 10 gauge is quite thick and may not be flexible enough for in-wall use. Be sure that the cable is CL3 rated for in-wall runs. We recommend a 12-gauge CL-rated cable at maximum but the IWS-8 will accept a 14-gauge. If you use 12 gauge, you could strip it down on the end for the IWS-8 subwoofer. CL/MA 1619
    Daniel • 12/17/2019, 2:17:43 PM Can this be mounted into the ceiling? is that advisable?

    Hi Daniel, You can mount this subwoofer in the ceiling or wall. The IWS-8 has an infinite baffle design but will sound different depending on the material behind the wall or ceiling that affect the sound pressure level. CL/MA 1622

    Remember the Paul Simon song: "One Man's Ceiling Is Another Man's Floor" Dont' put a subwoofer in the ceiling below a bedroom or other quiet room. No one will be happy with that outcome.
    Evan • 12/17/2019, 2:17:43 PM Hello, The SMP60 webpage indicates that the amp will work for this sub, but I think the answer to the question asked by Migoni says that it won't. Can you confirm? Also, when a subwoofer is in-wall, is there a lot of vibration in the wall? I was actually thinking of mounting this in an empty void under my kitchen counter and was wondering if you thought it would give off to much vibration. Thanks
    Customer Service • 12/17/2019, 2:17:43 PM
    Hi Evan: The answer did not fit the question, Migoni was asking about single IWS-8 In-Wall Sub, the answer said the SMP-60 would not drive dual 8". The IWS8 is a single woofer so I will need to edit that answer. You can build an enclosure under your counter. The stronger the box, the less chance of vibration being a problem. You will also want to stuff the box with Fiber fill. Question, are you using this sub as part of a home theater or just to add to a two channel system in that room? I hope that helps. Also see answers provide below Migoni question for enclosure size. You will be a little bit different since you will not be dealing with a normal wall cavity 3.75"depth between two studs 16" apart on center. So think 1.5 to 2 cubic feet. You can make it smaller if you use more fiber fill. Good Luck TL/3781
    Ryan • 12/17/2019, 2:17:43 PM I have the smp60 and the 8" inwall sub from OSD. For some reason I can BARELY hear the sub, only if I put my ear up to it. I have the amp all the way up. Thoughts?
    Customer Service • 12/17/2019, 2:17:43 PM
    Hi Ryan: Are you using this with your Home Theater or in a 2,1 music system? If you are using with an AVR, Audio Video Receiver have you checked the volume setting for the Sub-woofer in your setup menu of the AVR? Can you tell me what your basic. What do you have your hi cut filter set at, the knob on the left. Start with it set to 150 Hz all the way to the right. This is your cut-off for high frequencies and if you have it set to low and and your source may not go that low. Please let us know if this helps TL/3786
