MartinLogan Dynamo 500 10″ Subwoofer 360W Peak – Black
This MartinLogan Dynamo 500 powered subwoofer delivers tight, articulate bass from a compact footprint, with a 10-inch driver and 120-watt RMS (360-watt peak) amplifier that make it a very powerful option for serious home theatre or music in very good condition.
The Dynamo 500 uses a front-firing 10-inch high-excursion polypropylene cone woofer and dual rear low-turbulence ports, giving it deep extension down to about 29 Hz while keeping port noise and distortion low. Its 120-watt switch-mode amplifier is designed for low noise and low distortion, providing ample continuous power with 360 watts of peak capability for movie effects and musical transients. A continuously variable low-pass crossover (50–200 Hz), phase control, and level adjustment make integration with main speakers straightforward, whether you are adding it to a two-channel system or a full surround setup. Line-level stereo/LFE inputs support easy connection to AV receivers and stereo amps. In very good cosmetic condition, this unit presents well with only light signs of use on its black ash-style finish.

The passive subwoofer that shipped with LG's SH96TA home-theatre system — forward-firing driver and a front port, so it can back onto a wall or sit inside a cabinet without upsetting the tuning. It is a 3-ohm load and needs a receiver with a dedicated passive-subwoofer output; it should not go on ordinary speaker terminals. No power cord, no plate amp to age out. Good cosmetic condition.

JVC SX-PW33 Slim Tower Subwoofer — 6.5in, 100W, High-Pass Out
A tall, narrow bass column meant to stand beside a cabinet rather than in front of it — 8.25 inches across the front and unusually deep at 17, which is the trade: the depth buys back the internal volume the narrow baffle gives away, so a 6.5 inch woofer is properly loaded in a strip of floor barely wider than a hardcover book. Driven by an integrated 100 watt amplifier, with speaker-level inputs and high-pass outputs so it works with an amplifier that has no subwoofer output at all. Good condition.
