Car Audio question: Tube vs. everything else

http://www.gotapex.com/ubb/Forum10/HTML/000092.html __________________ bazooka tubes are actually pretty nice. i was considering one for my hatch-back, but i ended up getting a full-range box instead. i remember seeing some on ubid a while back. __________________ How do they compare to a similarly priced conventional box, sound quality-wise?
