[. . . ] The 215PCM can supply extreme SPL within the recommended bandpass of 35-150 Hz (-3 dB). The 215PSB is a powered subwoofer, but without the "top-box" electronics. The power and processing electronics of the 215PCM are contained in a backpack mounted on the rear of the subwoofer enclosure. [. . . ] The drivers face each other and move equally but in opposite directions. The net effect is that the driver forces counterbalance, minimizing vibration in the cabinet. Key Features Highest output to size ratio available 3000W powerplant for sub (215PCM and rigidity of the cabinet walls raises the enclosure's natural resonances to frequencies higher than the subwoofer's operating range, so the cabinet acts more like an ideal enclosure. Composilite construction significantly reduces the weight of the subwoofer, making it easier and more cost-effective to transport. The system is designed for single-person portability; by leaning the cabinet back onto its two casters and grasping the handles at the upper rear corners, one person can easily roll it across a floor or other flat surface. Sir Isaac Newton's third law of motion states that to every action, there is an equal and opposite reaction. Subwoofer cones have significantly higher mass than those of other types of speaker driver, and the low frequencies they reproduce require large displacements. Thus, the forces that move the cone forward and backward also make the enclosure move the opposite way in reaction. The enclosure's vibrations tend to turn its walls into radiating surfaces and its supporting feet into walking appendages. However, a lightweight enclosure like the 215PSB) ­ 3600W, 2 channel powerplant for accompanying top enclosures (215PCM) User configurable DSP for both sub and Port top enclosures with eight storable presets for each (215PCM and 215PSB) Removable backpack houses processing and amplification for system (215PCM and 215PSB) Dual High power 15" drivers rated at 1400 watts each Diametrically opposed drivers for 18. 38" increased efficiency and output Cored Composite construction results in greater rigidity, increased output, reduced off axis resonances and lighter weight Weather and UV resistant durable enclosure Reinforced, integral suspension fly track Port 24. 0" for vertical or horizontal hanging QSControl compatible for remote monitoring and control Integrated heavy-duty pole cups on top and side for pole mounting top boxes The movement of the two separate drivers counteract, reducing enclosure vibration.
