Paradigm Monitor SUB 12 v7 900W 12-Inch Sealed Subwoofer

Paradigm Monitor SUB 12 v7 900W 12-Inch Sealed Subwoofer

A very-good-condition Paradigm Monitor SUB 12 (Series 7) — a 12-inch sealed acoustic-suspension subwoofer with a 900-watt Dynamic Peak / 300-watt RMS Ultra-Class-D amplifier and DIN-rated low-frequency extension to 16 Hz, all packed into a remarkably compact, room-friendly cabinet.

The Monitor SUB 12 is the flagship of Paradigm’s Series 7 Monitor subwoofer line and represents a real engineering achievement: genuine 12-inch full-range bass extension from a sealed cabinet measuring just 15 inches tall. Where most 12-inch subwoofers demand a substantial floor footprint and a ported cabinet to reach into the bottom octave, the SUB 12 uses a high-excursion driver, a high-current Ultra-Class-D amplifier, and Paradigm’s acoustic-suspension cabinet engineering to deliver tight, fast, musically articulate bass with the kind of pitch definition that ported subs frequently struggle to match.

The 12-inch driver itself is a serious piece of engineering: a 305 mm carbon-loaded polypropylene cone, a 2-inch 4-layer copper-clad aluminum voice coil, dual Nomex spiders, a 6.5 lb ferrite magnet, and Paradigm’s AVS die-cast heat-sink chassis — all hallmarks of Paradigm’s higher-end driver design philosophy translated into the Monitor price tier. The Ultra-Class-D amplifier delivers 900 watts of dynamic peak power with 300 watts of continuous RMS output, offering generous headroom for film effects and large-room music duty alike.

Connectivity and setup are straightforward: dual RCA line-level inputs (L/R or sub-out / LFE), variable low-pass filter from 35 Hz to 150 Hz with bypass option, variable phase from 0° to 180°, auto-on / off, soft-clipping, and thermal protection. The integrated USB port supports Paradigm’s Perfect Bass Kit (PBK) for active room correction (sold separately), and the SUB 12 is wireless-ready via Paradigm’s PT-2 transmitter (also sold separately) — useful flexibility for owners who want to relocate the sub without a long signal cable run.

This particular unit is in very-good cosmetic condition, presenting cleanly in its black-ash finish with the typical light handling marks consistent with careful use and no significant blemishes to the cabinet, grille, or rear panel.
