OSD Audio 8" in Wall Subwoofer 150W Easy Install, Paintable Grill IWS8

I bought several Rocket UFW-10 subwoofers back in 2005. They were really good, tight bass, not muddy at all. Well, the amps all went bad on the enclosures and I didn't have the heart to trash them. I thought about replacing the amps at first and looked for the right plate amplifier to replace the dead ones on the 3 UFW-10s but I couldn't justify the spend. I decided to leave them unpowered and started using them as my main front left/right woofers and as the sub for my PC. The UFW-10 connected to my PC goes through a soundbar and is powered by a 2 channel 100 watt amp. The bass just wasn't banging with the one channel so I stated looking at adding a second subwoofer to the setup instead of buying a new more powerful amp, cost/benefit and the cost was too high for a better amp. When I checked out the specs for the OSD IWS8 and the price I decided to give them a whirl. The IWS8 mounted perfectly in the UFW-10 and now it slams with the cheapo 100 watt amp on my PC. For just $100 more I decided to do the same hack to my front left/right speakers. I added some passive crossovers to the mains. I can't really vouch for mounting these in a wall. They may be missing a little on the low end but I can say that they compliment my old USW-10 speakers perfectly and at an unbeatable price point. I would recommend mounting them with some foam rubber around the lip as pictured.

Great speaker! Great price! Finished my surround sound system.

driver only no frequency control network, needs special subwoofer amp, sound not great

Rarely write positive reviews, with the exception of product I feel is underrated. I installed this sub in basement wall. Installation was straight-forward with in-wall bracket really allowing you to torque the screws for a tight fit. I powered thus sub with a 2.1 channel amp ZK-TB21, which powers this sub with 100W and the bass is impressive and surprisingly hard-hitting. Buying a second now for my bedroom.

Waited until my workout room was done and woofer was installed to rate it. First, the people saying it lacks deep base are wrong. If you want house shaking base get a big powered sub, this has much more thump than I’ll ever need. My big complaint is the mounting system, the bracket is poorly designed as stated in other reviews, I had to cut and modify it to get it to seal and not vibrate, I also suggest boxing it in the wall if possible, made a lot of difference. Lastly, remember you need to amplify it to get any base out of it, I got the cheap Fosi amp and it works great. Summary: very good deep base for wall mount sub but the install should be a lot less complicated, all of my other speaker have the flip ears that work great for inwall and in ceiling mounting, this should as well.

Good quality

Speaker is very clear gives a loud bass, but will not win any competitions

I'm using a 250w Dayton Audio amplifier ( Dayton Audio SPA250 250 Watt Subwoofer Amplifier ) with two of these OSD Audio IWS10 drivers. I haven't been able to over-drive them yet, but I haven't tried. I get a HUGE thump when cranking the volume. In my case, they are floor-mounted in my home theater risers (one under each row). The risers are blocked off to make a nice, large solid wood cabinet which I'm sure helps the sound. You can feel them throughout the whole 13'x5' riser. The sound does not rival Boston Acoustic subs, but they are solid and amazing for the price! I'm going to install another one in another part of my basement.

After reviewing other models and sizes this one made the most sense. Received this OSD IWS8 inch subwoofer speaker in February 2020, this speaker was installed nicely in the lower wall of my home and works in conjunction with my whole house ceiling speakers, this speaker is wired in parallel with another 8 inch active sub woofer that is on the other side of the house to create a balance low end respond, it is driven with the OSD SMP-100 sub amp that is wired to a 4 channel speaker switch to balance the impedance of all the speakers, when driven these speakers produce a deep solid bass that help to shape the sound nicely with the ceiling speakers even at a low volume, I am very happy with this speaker and would recommend it to anyone that is thinking of purchasing it for a whole house setup. (See sub amp review by me)

Buen producto. Pero tengan cuidado porque compré 4 me hicieron el cobro por las 4 y después me hicieron la cancelación de una y nada más me entregaron 3, nunca me reembolsaron el cobro de la cuarta

La descripción del artículo indica claramente un par de altavoces, al llegar la entrega solo es un producto. En México un par significa que son 2 piezas del producto. Devolución inmediata.

Sound great!

Good unit for the money!!
