3. FEATURES Full range biamp operation Dual 1505 8DT woofers High power handling polypropylene capacitors 16 gauge plasticized metal grille Interlocking top bottom for stackability DESCRIPTION The new DTH 4 was designed as true minimum profile enclosure It measures only 1834 at its widest point up front while tapering to a mere 9 at the back Because of the trapezoidal geometry cf these enclosures building arrays is much easier This shape also greatly reduces standing wave build up within the enclosure The DTH 4 is a pseudo three way system using a 1505 8 DT woofer and 447 compres sion driver coupled to a CH 5 horn This is a constant directivity 809 x 40 horn A second 1505 8DT woofer is us ed to reinforce the low frequency response of the system The CH 5 used in this application has been cut down to allow it to fit in the narrow baffle area Access to the 44T is gained by remov ing the bolted on top Recessed areas have been provided on the top that coincide with the placement of the feet on the bottom This allows integral stacking of enclosures An internal passive crossover is utilized to enable the system to run full range directly from the factory Bi amp operation is also possible simply by moving a few jumper connectors on the circuit board High power handling polyporpylene capacitors are used throughout the crossover This results in a cleaner sound especially at high power levels as
