Can this be used as a drop-in replacement woofer for an existing powered or passive cabinet?

Yes. The HA-P15WS8 directly replaces the woofer in the Mackie Thump 15 (Thump15A TH-15A) powered cabinet. It uses the factory mounting points with no cutting, drilling, or adapter rings, and its 8 ohm impedance matches the stock driver.

What size is this speaker and what are its power ratings?

15 inch pro audio midrange PA woofer rated 150 to 400 watts RMS and 800 watts peak. Single voice coil, 8 ohm, 93.7dB sensitivity, 37Hz to 4kHz frequency response. Restores full low frequency output to the Thump 15 cabinet after the driver swap.

What exactly is included in the box, and is any mounting hardware or documentation provided?

Includes the Harmony Audio HA-P15WS8 15 inch woofer in an 18 x 18 x 8 inch carton, 27.4 pounds. No mounting hardware is listed or needed; it bolts to the Thump 15's factory mounting points with no cutting, drilling, or adapter rings.

How much amplifier power do I need to drive this speaker safely?

Plan on 150 to 400 watts RMS into 8 ohms, with 800 watts peak as the absolute ceiling. In the Thump 15, the built-in amplifier handles it since the driver's specs match the stock woofer, and 93.7dB sensitivity helps it play loud efficiently.
