    I was lucky enough to win a 20-39PCi in the SVS giveaway contest. One of the stipulations was I had to post a review. Given the generousity of the SVS folks, I think it's the least I can do [​IMG]
    my previous sub was a modified sony SA-WM40. It was stuffed with about 1lb of polyfill, and the stock driver was replaced with an original SVS driver. So that's my basis of comparison. My room size is about 20' x 15' with 8' ceilings.
    Being a HT geek, I'd been following the SVS hoopla here on HTF and was very excited to be getting my own. When it finally arrived, I was initially a little surprised how small it was. It wasn't even as tall as my floorstanding mains. I went through all the necessary calibrations (using AVIA) and set it about 4dB above the other speakers. I then set the overall volume to the normal listening level and fired up the pod racing scene from TPM (on DVD). I was impressed, but my socks were still on. There was more bass, sure, but nothing hanging from the walls was rattling. So I turned up the overall volume a little bit and that made it a bit better. Apparently my normal listening volume wasn't loud enough. I tested out a few more choice scenes (including the Matrix lobby scene and the Jurassic Park DTS T-rex scenes) and ended up boosting the sub level another dB or two (more than that and it started to overpower the other channels). I also played a bit of music (CD Audio and DVD Audio) but the perceived increase in bass was no where near as much as with the movie scenes I tested.
    I haven't done any measurements or EQ'ing yet, but as things are the SVS provides a good deal more bass (in quantity and extension) than my previous SA-WM40. The big question for me (if I had purchased the SVS) would be is it $500 better? I would say yes it is, but only if you are able to turn up the volume enough to appreciate it, and only with content that has a significant amount of sonic info

    Matt:

    I own the Sony SA-WM40, and I am curious to know how much improvement you got by adding the SVS driver (I have already done the polyfill mod). Also, was their a compatibility problem, e.g. did you have to drill more holes? Was it worth it?

    Eric - Matt won the whole SVS sub in a contest offered here a couple months ago. He didn't get a new driver for his Sony sub.

    Rob,

    before I won the SVS, I replaced the factory driver in my SA-WM40 with a first-gen SVS driver that people were selling on the FS forum.


    Eric,

    the SVS driver was slightly larger than the stock Sony one, so I had to enlarge the opening a little. I also drilled new holes. I'd say the improvement was noticable, moreso for music than HT, because the SVS driver was tighter/faster and the extension was limited not by the driver but by the enclosure size/port tuning. the upgrade cost me $40 for the driver and an hour of my time, and I'd say the result was worth it (but then I'm a tweaker at heart)

    -Matt

    My 25-31PCi blends in pretty well with my music. I have my receiver x-over at 70 for fronts(front spec'd to 35Hz) and I get great bass. I find that compared to my system with out the sub and set to large, (the source material can make a huge difference) the sub integrate much better than I anticipated and I prefer it this way. My only problem is that since I have the sub 4db's hot(I don't run reference ) sometimes I have to turn it down a hair.
