ever since alpine added the multi-roll surround to the type r i've liked it.

also i've taken more accurate and faster responding shits than most subs kicker has released. of course i never listen to any booming bass tracks, i'm a double bass man, so quick response/accuracy > spl.

and don't bother with alpine's amps. they may be the best you'll find at best buy or circuit city, but there's much better out there. their s/n ratio is borderline shitty. i assume that's a byproduct of trying to pack too much power into such small packages.
