SVS SB-1000 Pro vs SVS PB-1000 Pro
Sealed or ported at the same $599.99 — which should you buy?
Same brand, same $599.99 tracked price, same 325W RMS amplifier and 12-inch driver — the only real variable is the box. This is the purest sealed-vs-ported decision in our catalog.
Reading the numbers honestly
This comparison is a rarity: both extension figures are stated at the SAME ±3 dB tolerance — 20 Hz (sealed SB) vs 17 Hz (ported PB) — so for once the two numbers can be compared as printed. Most sub spec sheets don't grant you that; when tolerances differ or go unstated we say so, and here we can honestly say the ported box digs 3 Hz deeper by the same yardstick.

The verdict
Buy the SVS SB-1000 Pro for a small room or shared walls — sealed roll-off plus room gain is the controllable choice, and it's the box you can actually place. Buy the PB-1000 Pro for a bigger dedicated room where its like-for-like 17 Hz (±3 dB) extension and ported output earn their bulk.
Apartment / small roomSVS SB-1000 Pro — Sealed rolls off gently into the region room gain returns for free; it's also the smaller box.
Dedicated movie roomSVS PB-1000 Pro — 17 Hz vs 20 Hz at the same stated ±3 dB — a genuine, like-for-like extension win.
Music-first listeningSVS SB-1000 Pro — The sealed alignment is the tighter, more controlled of the two designs.
What our normalized data addsNOT ON THE SPEC SHEETS
- A rare like-for-like extension comparison: 20 Hz vs 17 Hz BOTH stated at ±3 dB — same brand, same yardstick, directly comparable, and we can prove it from the stored tolerance field.
- Same $599.99 tracked price, same 325W RMS, same 12" driver — the enclosure is the entire decision, isolated cleanly.
- The sealed SB-1000 Pro additionally lists built-in room correction in our data — a control advantage in untreated rooms.
