OSD Trimless in Wall Subwoofer Dual 8" Woofers 300W Sealed Enclosure Magnetic Grill SL800

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.

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.

Los altavoces no traen sus especificaciones técnicas completas, el manual no cuenta con la información de los parámetros Vas, Fs, QTC, QTS, los cuales son fundamentales para el diseño de las cajas acústicas en aquellos casos en los que no pueden ser empotrados en el techo o la pared. A pesar de haber consultado al vendedor y al fabricante en repetidas oportunidades no he recibido la respuesta sobre estos parámetros, los cuales deben ser de total conocimiento de la marca.Si no puedes instalarlos en pared y techo o consideras fabricarles cajas de resonancia no aconsejo en lo absoluto esta marca y referencia.

It does the job it’s not a 12 inch so it’s maybe there isn’t as much really low frequency purchase some would like ( hence go buy a 12 inch sub) but I like the fact it’s enclosed and fits between the joists at standard width. Do check that your spacing is wide enough before you cut the opening, some builders don’t always space at exactly the right spacing. One thing I would really recommend is make sure you have all the front location screws in and sufficiently tight or it will rattle, once I made sure they were really secure it sounded excellent for what I wanted, it’s only paired with a 100watt sub amp, enough for what I wanted

After a recent man cave renovation I had installed 6 8" In celling speakers which were lacking low end. I purchased 2 of these OSD Dual 8" Subwoofers to provide a more full sound. After installing both speakers 4 8" Subwoofers in combination with my previously installed 6 8" full range in celling speakers I am in no way disappointed. My man cave now doubles as a night club with some seriously thumping bass!

Seems to be well constructed and very easy to install. Would like a little bit fuller bass, but for the price it’s acceptable.

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.

For an in wall sub-woofer this is a good one. I'm powering it with a Bash 500 amp. It has a nice smooth bass to it. It is not a blow your windows out sub, but it helps to fill in the lows nicely. I've used it for about a month now with movies and music. It has helped the overall sound quality of my system which is a yamaha v673 receiver with Outdoor Speaker Depot IW545 for left, center, right and MK850's for the two rears. The one thing that I have noticed is that the sheet rock around the sub is showing a few nail pops causing a bit of vibration with the sheet rock. I added some screws which has solved the problem so far. If your looking for a sub that has a nice clean and smooth bass this is a good pick. I'm not an audiophile, but just enjoy good sound.
