Final Take
I tested the IWSub 10/10s with a variety of music and movie clips, and I have to say that I was very, very impressed. The bass was tunable to my test room very easily, and there was never any boominess or bloated-sounding bass notes. Bass response was smooth and resolute, and made for a very pleasant experience. It sounded great while listening to Beck's 5.1 and stereo mixes of his new album Guero, a mix of electronic hi-fi with decidedly low-fi sounds, which is a challenge for even the best systems. Particularly, on the track "Girl", which is a bass-driven piece, and definitely a challenge for almost any system, it did an extraordinary job with virtually no tweaking.

The IWSub 10/10 filled the room with just enough bass energy, and was very quick in getting the bass in and getting it out, so it always sounded clean. I had similar results while listening to Peter Gabriel's SACD of his last album, Up. Again, a challenging album with deep bass presence, and many systems just aren't up to snuff. However, this was not one of those systems, and it passed with flying colors. In particular, the track "Growing Up" was an exciting experience to listen to, and its pounding rhythms were as they were likely designed to be - unrelenting and evocative.

On bombastic movie soundtracks like Sahara and National Treasure (both terrible movies), the IWSub 10/10s were equally impressive. During crashes and explosions, the bass response was clean and powerful, making for a very vibrant viewing experience. I didn't want to turn off the movies, even though they were pretty horrendous, but they sure sounded great with these in-wall subwoofers!

If you have the opportunity to cut into your walls and install the perfect subwoofer for so many installations, then do it. The price is great for what you get, and as I mentioned above, you can even pair up two subwoofers with one amplifier, and the results are spectacular. If you are renting, you can still go ahead and install this speaker package, as long as you are okay with losing your security deposit. If you own your own place, it's a no-brainer, and it'll also surely make your significant other happy by cleaning up the clutter in your home theater or media room. Either way, you'll be happy in the long run.
