Waste of money. JBL 2245H an excellent transducer though.
Paramilitary XJ-500 21st Century technology from 1986. Before the said transducer is acquired, the "trick" is finding the right horn + transducer synergy.
Tranvex Music have announced their "revolutionary" new Electradyne XJ-500 15" Bass Driver with 12.5" magnet. Apart from claiming this high sensitivity unit can generate four times more power than ordinary bass speakers, they say that, "In full horn bass enclosure, tests sound pressure levels have reached a believable 145db with a power handling of 3000w (Peak)". Incredible. Phone (021) 236 9260 for details.
