Is sealed better than ported for music?

Sealed subs roll off more gently and tend to sound tighter, which suits music. The PB-2000 Pro has a sealed port mode that narrows the gap.

Can I run two SB-1000 Pros instead of one PB-2000 Pro?

Yes, and for smoother bass across multiple seats that is often the better choice in a small or medium room.

Do both work with the SVS app?

Yes. Both have app control with parametric EQ, crossover, and phase settings.

Head to head

SVS SB-1000 Pro vs PB-2000 Pro

A compact sealed 12-inch against a ported 12-inch with more amp and deeper extension. The deciding factor is room size and how much you care about movie bass.

Most people comparing these have a room in the 1,500 to 3,000 cubic foot range and are torn between a small sealed box that fits anywhere and a larger ported one that hits harder. The one question that decides it: is this a music-first system in a small room, or a movie-first system in a medium one?

Pick the SVS SB-1000 Pro if

Your room is under about 2,000 cubic feet or the sub has to hide under an end table.
You listen to more music than movies and want tight, fast bass.
You plan to buy two subs on a budget for smoother bass across the seats.

Pick the SVS PB-2000 Pro if

Your room is a medium living room or open to other spaces.
Movies come first and you want weight below 20 Hz.
You have floor space for a cabinet two feet deep.

Verdict

Buy the PB-2000 Pro for a medium room where movies matter; the extra output in the 20 to 30 Hz range is what you feel in your chest. Buy the SB-1000 Pro for a small room, a music-first system, or when the sub has to disappear. The exception is a small room with a movie focus: two SB-1000 Pros often beat one PB-2000 Pro there.
