How does the SB-3000 R|Evolution differ from the older SB-3000?

It uses a new 13-inch driver and an amplifier and DSP platform derived from SVS's flagship lines. SVS rates it to about 17 Hz, with the same sealed, compact approach as the earlier model.

Is a sealed subwoofer good for movies?

Yes, but with a trade-off. A sealed cabinet like this one gives tight, controlled bass and a gentle roll-off; a ported sub of similar size will usually play louder at the very lowest frequencies.

What size room does it suit?

SVS positions it for medium-sized rooms where accuracy matters more than sheer output. In large or open rooms, expect to add a second sub or step up to a bigger model.

How low does it actually go?

SVS rates the response at 17 Hz to 230 Hz, ±3 dB. Real in-room depth depends on placement and room gain, so corner or wall placement will change what you hear.

What comes in the box?

The subwoofer with its grille. Check the listing for the included power cable and any setup accessories, since SVS has changed bundle contents between models.
