Smooth mid to high freq. response and great bass
This speaker received poor reviews from people who dont know what they have. They needs more than head unit power to reach potential and can take more clean power than what they are rated for. There is no comparison to the the Infinty speakers that some have mentioned. Once you give these a chance (and some power) they are hands down the better speaker if you want your music accurate and uncolored. The infinities have a very bright, artificial and (to my ear) harsh sound to them and will induce ear fatigue after a short time. These Alpines however are full and rich and wonderful IF you drive them with an external power amp of 60 to 100 WPC RMS. I've been at the car stereo game since the 70s (that's right I'm an old timer but there isn't a kid around who's system compares to mine). I've owned my own shop and done custom installs and had one of the first true component car stereo systems around back when everyone else was still amplifying distortion with "power boosters". I always liked my music clean and uncolored. If you prefer overly harsh "make your ears bleed" highs then I suggest the infinities are more your style but if you prefer clean, full and rich sound accross the entire freq. range, you should give these a listen. Just remember that when compared with most other speakers on the board at your local shop, they will sound like they're at 1/2 volume. Tell them to amp them and turn them up and you'll hear them come to life. You'll be glad you did. On the other hand, if you plan to drive these with your head unit power only, you might want to pass on them for something more efficient unless you plan to add an amp later.
