User manual QSC AUDIO 215PCM BROCHURE

[. . . ] The 215PCM can supply extreme SPL within the recommended bandpass of 35-150 Hz (-3 dB). The 215SB is a passive subwoofer system with no backpack electronics. 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. [. . . ] This reality presents a challenge for subwoofer cabinets. 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. The inertia of a heavy box naturally resists opposing motion. 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.
