JL Audio has more technologies than other woofers like for example cooling the voice coil more than any other sub. This probably makes the JL Audio expensive because of their technologies. Anyways, JBL, Kicker, Rockford Fosgate, Alpine, Pioneer, MTX, Bazooka, Sony Xplod, DB Drive e.t.c. have their own "stuff". This is just few main things about high quality subs. That's why best is not best. The loudest sound system was a grey 1990 XL Ford Van, in McAllen, TX. Santa Ana Mobile Mechanic

With adequate power, can play louder than any speaker I've ever used. Very accurate and tonally balanced. Tweeter stays linear at high volumes. | house washing

Great components from top to bottom

I bought these for $90...they are very very good speakers and are for the Audiophiles ears...they can take all the power my 4 channel Kenwood amp (rated at 320watts@4ohms)which gives out decent power...the tweeters and midranges are among the best i''''ve heard..and thats comparing them to the MB Quart Q series which retail for $1,200 and came out earlier this year...

The sound quality is amazing!!! I wish there were more than 5 stars possible.

Price - but you get what you pay for.

I can honestly say that I haven't bought anything that has given me as much long-term enjoyment as these speakers. I bought the second generation 6 1/2" component set 4 years ago for $400. I'm still using the same set today. At first I thought there weren't enough highs so I switched to Polks (EX), which use awesome tweeters, but the more I listened to them, the more I realized the a/d/s's were more sonically accurate, so the a/d/s's went back in.
The people at a/d/s are very friendly and very helpful. I've been corresponding with Pat Molettieri about recommendations for my new car, and every message I receive is helpful and insightful. They really know car audio and are willing to go the extra mile for their customers. Check them out at www.adst.com

Smooth, natural sound, not overbright or harsh

It should have been in my car 6 years ago!!!

I've been into car audio for 13 years now and officially jumped on the MB Quart bandwagon 8 years ago. These speakers slapped me right off that bandwagon on onto the a/d/s train. WOW, these are entry level? They just replaced their A series with the 200 series but its the same speaker basically. It has a warm, well balanced sound from top to bottom. I bought these off the internet for $200, they retail for $400. I'll bet the $300 coaxial version of this speaker sounds just as good. I'll be buying a/d/s speakers from now on. If your sick of the overbright, overpriced, overrated, tinney sounding MB Quarts, give this speaker a try. You won't be sorry

superb sound quality; fit and finish; value

These are trully superb speakers. I used these speakers to replace the stock component front speakers in my 99 VW Golf. The sound is mezmerizing. If you close your eyes (while the car is parked) it sounds like you are listening to the music live. The sound is near home audophile quality. I recommend pairing these speakers with the Eclipse 5543 cd/receiver, even without a seperate amp. I recommmend these speakers without reservation.
