Is the Rock Shaker 12 worth it at $199.95?

At $199.95 at Amazon as of November 3, 2026, it is a cheap way to add a 12-inch sub to a basic system. Expect loud, room-filling bass rather than refined, tight output.

Will it work with my receiver?

Yes, if your receiver has a subwoofer pre-out (RCA) or speaker-level outputs. It has both RCA line in/out and high-level speaker in/out.

Rockville rates it at 40 Hz to 200 Hz. That covers most music and TV bass but not the deepest movie effects below 40 Hz.

How big is it and where should it go?

It measures 16.5" x 20.5" x 18" and weighs 32.2 lb. Plan floor space near a wall or corner and use the phase switch to get the best blend with your main speakers.

What comes in the box?

The subwoofer, a detachable foam grille, and an IEC power cable. Speaker wire and RCA cables are not included.

Only one new price, $199.95 at Amazon as of November 3, 2026, is listed, so there is no recent range to judge a low point. Watch for holiday sales on budget audio.
