About the Monitor Audio IWB-10

Optimize your in-wall subwoofer's sound

IWB-10 back panel closeup

The IWB-10 comes pre-wired with high-quality external speaker connectors that help simplify installation.

If you're installing your Monitor Audio in-wall sub in a new home under construction (or in a room that's undergoing major renovation), use Monitor's IWB-10 enclosure for the best possible sound. This "in-wall cabinet" is custom made for the IWS-10 in-wall subwoofer. The engineers at Monitor carefully designed the enclosure to allow the woofer to achieve optimum low-frequency response. The rigid MDF construction and rugged vinyl laminate finish keep the bass tight and clean, while reducing the amount of bass radiated into adjacent rooms. For easier installation, the box is pre-wired with high-quality external speaker connectors, and Monitor provides adjustable steel mounting brackets.

  • compatible with Monitor Audio IWS-10 in-wall subwoofer
  • heavy duty MDF construction with laminated vinyl finish
  • fits into standard 14" stud bays (16" centers)

Customer Q&A

3 questions already asked

Can these be mounted upside-down?
[ Douglas  Jul 26, 2022 ]
1 answer
Greetings Douglas, and thank you for your question. Monitor Audio's manual has it being installed in wall. Upside down in wall would be fine as well, but in ceiling is not mentioned. Could be due to liability if something on the enclosure malfunctioned, and dropped down. Your more than welcome to contact Monitor Audio and see how they feel about an in ceiling install if that was your plan. Their number is 800-667-6065.

Can you run this in wall subwoofer with the rest of the speakers being Polk Audio? Plan on having a 7.2 system
[ Phillip  Jun 27, 2022 ]

Greetings Phillip, and thank you for your question. This is a subwoofer enclosure only. You would also need the Monitor Audio subwoofer, and the proper amplifier for it. The home theater receiver will not have a powered subwoofer output. Here is our part numbers of the subwoofer 893IWS10, and the amplifier 893IWA250.

Can these be mounted vertically anywhere in the room, or do they need to be near ground level?
[ Jason  Sep 13, 2020 ]
2 answers
I just mounted one at ground level at the front of the room and one at 51" (at the woofer's center) at the rear of the room. A lot of this has to do with my stud spacing. The subs are on the way so I haven't gotten them hooked up yet but I'll update this once I've got it all up and running. Since subs are non-directional I'm not anticipating any issues.
[ Eric  Sep 13, 2020 ]
The sound experts might have better advice For placement, but you can put it anywhere you have the space for it in a wall (full stud-to-stud with nothing else in the bay). I did mount mine fairly low, below a window, centered in the room.
