54. ycomb core to form a rigid seamless enclosure The extreme stiffness of Composilite construction prevents flexing of the cabinet enclosure significantly reducing energy loss due to cabinet vibration The result is reduced enclosure loss increased low frequency output and substantially less sound radiating from the back and sides of the enclosure for greater sonic accuracy Furthermore the enclosure s light weight translates to safer rigging and reduced handling costs The frequency response of the 215PCM is 35 to 150 Hz 3 dB Two 15 inch diametrically opposed facing each other drivers fire in opposite directions with equal excursion The net effect being the driver forces counterbalance minimizing vibration in the cabinet This is essential in lightweight ultra stiff cabinet designs to keep the walls from vibrating excessively and to keep the cabinet from walking away during use 215PCM Powered Control Module Highlights The PCM version adds a 55 pound amplification and signal processing backpack to the 215SB subwoofer cabinet This backpack houses two independent power amplifiers one for the subwoofer and one for the top boxes Driving the subwoofer is the equivalent of a bridged mode PL230 amplifier providing up to 3000 watts to the two 15 inch drivers Top boxes are powered by the equivalent of a PL236 amplifier 725 W ch 98 ohms 1100 W ch 4 ohms 1850 W ch 2 ohms Signal processing is provided by two DSP 3 Digital Signal
