    With the right amp and nothing getting in the way of the sound like grills,  these speakers sound amazing, i really like the tweeter protection bulbs they have saved me from over powering the tweeters many times. cross over customization is incredible it really makes the difference if you choose the correct chips for the set up you have. No distortion all the way up too ear pierceing levels. worth every penny even though it was alot. very dependable have had them for a year now play them loud and proud every day with no problems. be sure to use your Highpass filters, lows really hurt these speakers.

    (This is a followup review) I was initially disappointed in the speakers sound, and after trying everything, decided to remove the factory grills that covered them. Presto. PRES-TO. Night and day difference. Those inferior factory grills were blocking much of the sound. These have a detailed, realistic sound, albeit a bit on the bright side (I believe the vast majority of automotive tweeters are made this way purposefully ). The woofer however, seems to lag behind the tweeter in refinement. There isn’t much bass or midbass in it, and while 6.5 inch components aren’t meant to produce bass, it could stand to use a little more oomph in this department. These crossovers are a thing of beauty,( unfortunately the Bozos I hired to install this stuff took the easiest route possible for themselves and placed them in a hidden locations)The crossovers have actual heat sinks in them much like a small amplifier, and high quality parts throughout. I haven’t adjusted them yet, due to the difficulty in accessing them. Pros: Really neat looking crossovers that look like small amplifiers. There is enough metal and capacitors in them to give an electronics nerd multiple orgasms. The tweeters sound terrific. Cons: A bit pricey, woofer doesn’t sound as refined as tweets.

    The reviews I read about this speaker had me believing I would be transported to a sonic utopia where I sit on a velvet listening chair and have beer served to me from a platinum tray by a bikini clad supermodel in stiletto heels. Needless to say, that did not happen. These are disappointing for the money. They play loud, but that’s about the only redeeming quality. They sound a little thin, and the detail they extract is merely OK. They don’t warrant the money. If you have $350 burning a hole in your pocket, do not spend it on these (or any component speakers) Spend maybe a couple of hundred on your fronts and drop the rest into other audio equipment. You’ll thank yourself. Pros: Really neat looking crossovers that look like small amplifiers. There is enough metal and capacitors in them to give an electronics nerd multiple orgasms. Cons: WAY overpriced and frankly don’t sound that great.
