I recommend the SPS-400 as they deliver a good clean sound for such a small speaker. They are not agreesive on the highs and handle my Alpine 4 channel amp well 75x4. I replaced a set of Infinity Kappa's that were just to shrill. Can't really think of any cons except the spade connectors on the speaker are a little fragile. I broke one connecting it to female side of wire, but was able to solder another in its place easily.

I have 4 of these and a 10" sub in a 93 range rover and they sound better than the 5K sound system that came with it. The speakers are not the most efficient so I'm running it with a MB Quart amp 50wx4 and they sound perfect!! Inside a range rover, which is a huge space! For the money, it's hard to beat it. Also, you need a sub with these, these are not meant to fill in deep bass. Sonic was great, fast shipping, great staff, overall a great experience.

I've had these for about 6 months now and they perform well, especially for the price. They produce nice clear sound and decent bass. I am currently running an external subwoofer so don't have deep bass running through them, but they've handled everything else without distortion. I'd recommend them for anyone looking for a nice set of replacement speakers. I plan on hooking them up to an amplifier soon and think they will sound even better then. The only thing I wish is the tweeter was more powerful, but I think I am just used to my previous component tweeters which were a little more powerful.

Ok they are 4" speakers so they aren't going to pump out a lot of bass, but they are great on the mid and high range. The price seals the deal. If you are looking for small speakers, these are the way to go.
