I should note that I use and this review is for the P205, which is the updated version of the P205. I believe it is essentially the same, except in a different finish.

So firstly I should get out of the way that I had lots of problems with my first P205. It had issues with the amplifier blowing fuses as soon as it was turned on and had to be sent back to CSW 3 times until I was sent a different one. The new one has worked absolutely fine since I got it, so determine for yourself if it's an isolated incident or not.

The sub itself is alright. For the size, it hits pretty hard and goes decently low, and I think it would work well in a sub/satellite setup for movies.

In a dedicated 2 channel music system like I use it in, it's not quite ideal. I use it with Wharfedale Evo2-10 main speakers (previously used it with Cambridge Soundworks Newton M80s), an Onkyo receiver, and a Marantz CD player. While it is tighter than some subs in it's range, it sort of lacks definition and sounds a bit bloated. Kick drums tend to sound "fat" and bass notes don't really sound as tuneful as they should.

Additionally, it's rather difficult to blend. I have played with numerous settings and placements and getting it to blend with the main speakers can be a challenge. With the M80s, it was sort of either too much bass (as the M80s put out very good bass on their own) or the sub was pretty much off, but I was never able to find a good middle ground. The Evos I now use are a bit leaner in bass, so trying to fill out the low end without the sub intruding on anything has been difficult. I think the control boxes CSW used to sell with the P500 and P1000/1005 made doing all this a little easier, I wish they'd bring those back as they are compatible with the P205.

All that said, you can definitely do worse, and I think if you're looking for a small sub for movies I'd say this one is actually quite good. So if you're looking for something small that can make loud explosions, this might be for you, but if you're looking for something to fill out the bottom end of your bookshelf/stand mount speakers with tight and tuneful bass, I think you could probably do better.
