This is the highly regarded Polk Audio PSW 450 powered subwoofer & RM2600 Center channel. Many subs can perform well for home theater OR music listening. It’s hard to find one that can do both. You have one here. It was widely praised for how it cleanly articulates musical bass notes, whether subtle or with a wallop, without blurring or turning to mud. And yet with movies it’s 150 watt RMS (350 peak!) packs a punch that’s more than satisfying on the most demanding movie soundtracks. This sub has a front-firing 12” woofer and can be hooked up a few different ways, including unfiltered LFE (from a surround receiver) speaker level or RCA. It has a phase control (0-180) a continuously variable crossover (60hz-125hz) and of course volume and automatic power control. Size - it’s 15 1/8” wide x 17 1/2” high x 19” deep. $99.
