ive owned a lot of different audio equipment over the years for various purposes and quality ranges and perfer the sound of JL to most everything else ive had the pleasure to listen too.

kicker when kicker was good equipment
Rockford (see above)
DD
digital audio
CF
Alpine
JL
eclipse
Treo
Memphis
etc

IMHO when you buy JL you buy good american built equipment. not saying there isnt other good stuff out there it's just what i perfer.
