Features & Specifications

Few components add more to the home theater experience than a subwoofer. 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. The beauty of OSD Audio in-wall subs is that you'll experience that thunderous, room-filling bass without filling up floor space.

I'm planning on seting up a 7.2 home theater in my home and I want to know if I could use this subwoofer for this system (Onkyo TX-RZ820 --- https://www.onkyousa.com/Products/model.php?m=TX-RZ820&class=Receiver&source=prodClass )?
1 Answers
Hi Ed: This is a passive in-wall sub woofer. Your Receiver features dual pre amp outputs so you would need to add an external amplifier to connect to one of the outputs. You could actually power 2 of the IWS10 subs with our external amp SMP250. But checkout our PS10 or PS 12 Powered sub woofer which you can connect directly to the pre amp sub output. These feature a built in amplifier. And there is a reason they recommend 2 Subs. It gives you better coverage and an external powered sub allows you to experiment on location versus trying to figure out the best sounding location for your in-wall sub. We offer wireless sub kits in case you have problem running a wire to your sub locations. Good luck TL/4574

February 27, 2016
I am building a home theater system for my new house and am planning to install this 10" in-wall sub and power it with the SMP250 amp. I am installing the sub to face out from a wall that has Sheetrock on the theater side and is an open (unfinished/bare studs) storage room on the other side. I have read about how in wall subs can produce unwanted rattle/vibrations/damage and would like to know how to install this sub so that doesn't happen. Do I need to build a box to enclose the sub? If so what material and dimensions?
1 Answers
Hi Jeremy: Yes, building an enclosure would be very effective and having it open like you described, accessible takes care of half the battle. The size of the enclosure is not critical so I would start by looking to see if you have fire brakes as part of the framing where you have pieces of two x fours mounted horizontal to the Studs. If no fire brakes, we will just have to create some for your top and bottom to the enclosure. You will want a piece of 1/2 inch MDF to go on the back side of the Sheetrock. Figure 2 to 3 foot in length and an exact fit width wise to the studs. You will need to use the same template to cut out the hole as you will for the Sheetrock. You might want to use some smaller pieces of wood to wedge the internal MDF against the Sheetrock attaching them to the Studs. Then a couple of the two by four pieces for the top and bottom then a 3/4" piece of MDF for the back, screwed into the Studs and bottom and top pieces. You might want to add a terminal cup in the back panel to run the wires from the Sub Amp to the cup then terminated on the inside to the back of the IWS-10 (used to get them from Radio Shack). You can use some Silicone to help seal the box first internally and then on the outside after secure the back panel. You might want to use some fiber fill (stuff they stuff pillows with) as well inside the enclosure. Also recommend running 12 gauge speaker wire from your amp. I hope that helps TL/3726

Very Low Volume from the IWs-10 I purchased a Dayton Audio SA 230 sub amp as my SMP 250 was dead when I first tried to use it and customer service has been appalling since then. I connected it to a Yamaha RX-V671 as I have done with other speakers (Bose) but I couldn't hear anything until I upped the db on AC by 10db and used bass boost on the amp. Is there a mismatch here somewhere, do I need to change ohms settings somewhere please? I am not an audio expert but never had this issue previously. Thanks
1 Answers
HI David: I am sorry you had issues with our SMP-250, with you being from Canada did you buy it directly from us or through Amazon? Now regarding your setup using the Dayton Audio (which is almost identical to our SMP-250) you are connecting to the Yamaha RX-V671 with the single output to the LFE input on the Dayton Audio SA-230, is that correct? And if so you have set your front gain knob to to half (12:00 o'clock) and turn you Crossover knob to max all the way clockwise (from Yamaha Manual, page 35)? On our amp you have a single gain control which Dayton Audio list as Bass boost. The only difference they have a additional control knob with a choice of frequencies to select from as part of the bass optimization. Now you go to your Yamaha settings for the sub woofer (page 89 in owner's manual). LFE stands for Low Frequency Effect. You select the distance from the sub to your optimum listening/view area and can change the Phase (which should be set to 0 on your Sub Amp). There is nothing wrong with adding more gain with your bass optimization. Once you have set your controls on the Dayton Sub Amp the sub should be controlled from the Yamaha receiver so volume increases or decreases with the other 5 or 7 channels. Are you getting something out of the Sub woofer, just not enough? Have you built an enclosure or reinforced your wall. Please feel free to contact me and tell me about your customer service experience at tim@osdaudio.com and let me know about your settings. Good luck TL/3817

December 22, 2015
My house is pre wired for 5.1 home theater system in my media room. If I were to install this in wall Subwoofer, can this be powered through the Yamaha 370 receiver? Or Do I have to power it up with an additional amp? If yes are there any amps that can also be mounted flush on the wall?
1 Answers
Hi SN: The IWS-10 in-wall sub you referred to does need an external Power Amplifier. We would recommend the SMP-250 to power the IWS-10. You will want to use fiber fill in the wall behind the IWS-10 (the kind you find at store where they sell pillows). Your other option is to purchase a PS-10 external sub woofer along with our new wireless kit (due in the next two weeks) featuring a Transmitter connected to your sub woofer output on the Audio Video Receiver. And wireless Receiver would connect to the Powered sub woofer. You will need a location that has two AC outlets, one for the Powered Sub woofer and the other for the Wireless Receiver. The external sub woofer has an advantage in room placement over the In-Wall sub since you can test it in a number of locations to find the optimum spot. The in-wall sub can be hit or miss. TL/3632

Is it make a difference if I block off a section in the studs and mount the sub to make it like a box behind the sheet rock. would it sound better. I used this in a room in my house and sometimes it sounds like its blown.but it seems its either to much air space and its rattling inside the wall
1 Answers
Hi Kevin, That should actually improve the sound quite a bit. Having a back box will give you a fuller sound! That's why our powered subs sound so great!

I am looking to put a home theater 5.1 or 7.1 in a screened in porch. My wife wants ceiling mounted speakers. What would you recommend? Should the center and sub be in wall? The receiver will likely be inside and iPhone/Ipad controlled so I don't think I need an outdoor amp or volume control. Can you get me started? Best, Mike
2 Answers
Hi Mike, Thanks for showing interest in our products. How sealed off is the patio? Will moisture still affect this area? If so, you should check out our outdoor rated in-ceiling speakers. We have 6.5" or 8" versions - the ICE600WRS or the ICE800WRS. There are also dual-tweeter versions of each of those models which are sold as a single speaker rather than a pair. The subwoofer will be tricky, because the in-wall subs aren't rated for outdoors. We do have a rock sub (HF26) or an omni sub (OMSUB200) that can be outdoors, but need an amp to power them. Let us know if you have any further questions. Thanks! -BM 2250

I want to put these in my home theater that I building from scratch. The walls are open and I build any size enclosure for this subwoofer in the wall. I've seen lots of questions regarding this topic; but, no firm answers. What size is recommended?
1 Answers
Hi Rob, Determining the right size of the subwoofer depends on many variables, including room size and shape, surround sound speaker locations, etc. Without more information on your room, we can't give you a definitive answer. However, consider that the better AV receivers feature dual subwoofer outputs for a reason. Based upon the natural characteristics of the low frequencies in your room, a single subwoofer will tend to have dead spots. Also. it is easier to find the ideal placement of the subwoofer when using an external powered subwoofer. Take a look at our learning section for some helpful information on home theater subwoofers. https://www.outdoorspeakerdepot.com/home-theater-learning.html TL/MA #1552

Jasmine & Brian
from Pacifica, CA asked:
November 27, 2012
Hello, Are there any limits as to what type of amplifier one Can use with this Subwoofer? We are planning on building our own Monoblock Vacuum Tube Amplifier (such as the Velleman K8010 Monobloc Vacuum Tube Amplifier Kit). Would this sub be ok to use with such an amplifier? Any extra special wires needed? We feel that the larger the wire, the better the sound output, so even though it is only about 30' of wire that will be needed, we feel to choose a 12AWG for our application. What are your thoughts? I read some of TL's answers to other customers questions and hope we can get some advice as well. Thank you very much! Jasmine & Brian
1 Answers
Hi Jasmine and Brian, This subwoofer should work for your application; in fact you should consider utilizing two of these subs. According to the specs of the Velleman Monobloc, it will handle a 4- or 8-ohm load so using two of the IWS-10 in parallel would present the 4-ohm load. This will maximize the output from your system. Is this part of an audio system or primarily for home theater? If it is for home theater, consider separating the two drivers in the room; perhaps one in the front and the other in the back. If you mount these in the wall, it’s important to build an enclosure for isolation behind the woofer. (We are looking into the Thiele/Small parameters along with some recommendations of enclosure sizes.) These are infinite baffle and are designed to work in a broader range of applications (space available). Regarding the 12 gauge, bigger is better for running low frequencies. We typically recommend a minimum gauge on speaker wire, rarely a maximum gauge. For example we recommend a minimum 16 gauge up to 80 feet and 14 gauge up to 200 feet. A 12-gauge wire would work in your application, especially for 30 feet. Good luck! TL/MA 1418

Hi, Is this sub considered as an "infinite baffle" type? Thanks, Raj
1 Answers
Hi Raj, This sub is an infinite baffle, so it is adaptable to most in-wall applications. We recommend reinforcing the wall behind the sub if possible. The wall behind the subwoofer will receive more pressure and more bass than the front wall. New construction allows you to build an enclosure utilizing the studs. With retrofit construction, you may need to reinforce with more fiber fill than normal. CL/MA 1417

Project: Want to add 3 of these in a room with 6 in ceiling speakers 4 in wall and keep the existing tower speakers up front.. 12 to 14 speakers in all.. Plus the 3 in wall Subs.. Will1 large amp do this ..? Like 900 watts..? Or do the Subs need their own Amp.. If so How do 2 Amps one running the speakers the other running the Subs work together?
1 Answers
Hi Eric: I am assuming you are planning on connecting all the speakers in the room to the same source which means a rather large room or overkill in a small room. My suggestion would be looking at our AMP200 for your tower speakers, our MX1260 (12 channel amp) for your in-ceiling and in-wall speakers and then a SMP250 Subwoofer Amplifier for powering the Subs. I would suggest four IW10S wired series parallel so the sub amp would see a 4 ohm load (versus three wired in parllel). Note the AMP200 (or AMP300) would be plenty for your Tower speakers and the MX1260 would alleviate worrying about impedance matching since you would have 12 discrete channels or six stereo zones with a choice of two universal buss sources or direct input at each channel. Please contact me directly for further assistance and clarification. We would love to take care of your other speaker needs and wiring if you have not made that decision. I can even furnish you with a wiring diagram if needed. My email address is tim@osdaudio.com. TL

from Kansas City, MO asked:
January 3, 2012
I have studied hi-fi for many years and have found that the speaker's box is very important. Did you find that placing the speaker in a wall between the studs and top and bottom plates provided a suitable box? Did the subwoofer rattle the sheet rock or pop the nails? I have designed actual "sealed" boxes and installed between the studs and it really helped the speaker performance. I did not have any Theile/Small (T/S) parameters from the manufacturer to use in modeling speaker performance. Are T/S parameters available for all in-wall speakers?
1 Answers
Hi Jim, We could not agree with you more! A custom enclosure is very important, especially if you want more sound directed into the selected room versus out the back wall. These are actually excellent woofers at factory-direct pricing. Even if you add the cost of the custom enclosure, it is still a great value. I believe these subs are considered an infinite baffle so they can work in a number of different size applications. We do not have the Theile/Small parameters but will try an obtain them and add them to our features and specification on our site. Iwill try and email them to you as well. We would be interested in what design you come up with. Perhaps you could post some pictures for us. TL/MA

Sounds good but knocking noise
I have 2 of these in parallel wired to a SMP250 amp. So it's a 4 ohm load which should be fine with this amp. However, under even moderate bass, I get a loud knocking noise from the subs. These subs should be able to handle the SMP250 output right?

Good 10" woofer for small to medium room
I installed the woofer in a 5.1 system for a great room/sunroom area that was part of a 6 zone audio install. The customer runs a number of audio programs from there receiver and the DirectTV digital audio channels. The Woofer sits perfect on a smaller wall and by blocking an sealing the area that the woofer is installed in you can create some tight low end bass for a small to medium sized room. The connections will probbly not accept larger than 14 gauge wire. The mounting is different than other in wall speakers but needs to be that way for installing this type woofer.
