The PS6 is constructed of a tough 5/8-inch-thick, vinyl-laminated and lock-mitered MDF, weighs 23 pounds and measures 8.25x12.5x10-inches. The front panel contains two ports for increased bass, and frequency response is 45 Hz to 20k Hz (±3 dB, ref. 500 Hz). A front panel LED indicates power on and clip conditions. As with most self-powered systems, the PS6 is a bi-amplified design, and the electronics package includes a fourth-order asymmetrical active crossover at 2.6 kHz. The 70-watt LF amplifier drives a 6 1/2-inch magnetically shielded, mineral-filled polypropylene cone featuring a high-temperature voice coil and a damped rubber surround, while the high-frequency driver, a 1-inch magnetically shielded natural silk dome tweeter with Ferrofluid voice coil coolant, is powered by a separate 30-watt amplifier. An input level control has a range of 20 dB and offers a notched stop position at the -5dB position. Input connectors are both XLR and 1/4-inch for balanced and unbalanced sources.
