In this review, we will be comparing Monitor XT10 and PB-1000, two Powered Subwoofer speakers from Polk Audio and SVS. Being Powered subwoofers, they both have built-in amplifiers so you don't need an external power amp or an integrated amp to power them. Let's have a brief look at the main features of Polk Monitor XT10 and SVS PB-1000 first before getting into our more detailed comparison.
The sections below take each area in turn: driver and amplifier, frequency response, physical size and connectivity.
Drivers
The efficiency of a subwoofer is directly proportional to the total radiating are squared hence the woofer quantity and diameter.Polk Monitor XT10and SVS PB-1000 have the same driver set up: Both subwoofers have 1 x 10" drivers.
Frequency Response
Monitor XT10 has a frequency range of 24-160 Hz whereas PB-1000 has a frequency range of 19-270 Hz. With a minimum frequency of 19Hz, the PB-1000 can go significantly deeper on the low side and provide stronger bass compared to the Monitor XT10's min frequency of 24Hz.
Below graphs depict how these two speakers compare with the max, min and average values of the Min and Max Frequencies of other speakers in the Subwoofer class in our database.

Cabinet Type
Both Polk Monitor XT10 and SVS PB-1000 have Bass Reflex type cabinets. Bass Reflex type subwoofers (aka Ported, Vented or Reflex Port) have enclosures that uses a port, hole or vent cut into the cabinet. Ported designs are generally more efficient than the Sealed designs.
Physical Specs
The size of a speaker can sometimes be an important decision factor due to space constraints or in some cases purely for esthetic reasons. In this section, we are going to compare Polk Monitor XT10's and SVS PB-1000's external dimensions. Polk Monitor XT10 has external dimensions of 399.0 x 302.0 x 422.0mm (15-11/16 x 11-7/8 x 16-5/8inch) whereas SVS PB-1000 has external dimensions of 480.0 x 381.0 x 532.0mm (18-7/8 x 15 x 20-15/16inch).
SVS PB-1000 is clearly the larger of the two speakers. Its body is 79mm wider, 81mm taller and 110mm deeper than Polk Monitor XT10.
Size, drawn to scale
Both speakers and both views share one scale, so everything here is directly comparable. Hover a box for its dimensions.
One scale for both, standing on the same surface and pushed back to the same wall, so the deeper one visibly sticks out further.
SVS PB-1000 needs about 59% more floor or shelf area. SVS PB-1000 is 110mm deeper, so it stands that much further out from the wall. SVS PB-1000 is 81mm taller.
Base Surface Area Comparison
Base surface area of a loudspeaker may become a determining factor when the space in your room or desk is limited.
The base surface area of the Polk Monitor XT10 is approximately 1274.4cm2 / 197.5inch2 and base area of the SVS PB-1000 is approximately 2026.9cm2 / 314.2inch2. The Monitor XT10 requires 37% less surface area than the PB-1000 which gives it a small advantage on placement in tight spaces.
