In this review, we will be comparing Stratton 12 and PB-1000, two Powered Subwoofer speakers from KLH 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 KLH Stratton 12 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.Both KLH Stratton 12and SVS PB-1000 have a single woofer setup however the KLH Stratton 12's woofer is 12-inch whereas the SVS PB-1000 features a 10-inch woofer.
Frequency Response
Stratton 12 has a frequency range of 25-160 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 Stratton 12's min frequency of 25Hz.
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 KLH Stratton 12 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 KLH Stratton 12's and SVS PB-1000's external dimensions. KLH Stratton 12 has external dimensions of 450.0 x 391.0 x 518.0mm (17-11/16inch x 15-3/8inch x 20-3/8inch) 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).
KLH Stratton 12 is 30mm shorter and 14mm less deeper than SVS PB-1000 but it is also 10mm wider.

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 KLH Stratton 12 is approximately 2025.4cm2 / 313.9inch2 and base area of the SVS PB-1000 is approximately 2026.9cm2 / 314.2inch2. The Stratton 12 requires 0% less surface area than the PB-1000 which gives it a small advantage on placement in tight spaces.
Weight Comparison The weight of a subwoofer may become an important factor if you need to move and reposition the unit often to find the optimal positioning, also known as 'Subwoofer Crawling'. The KLH Stratton 12 weighs 20.00kg / 44lbs and the SVS PB-1000 weighs 20.91kg / 46lbs. This makes the PB-1000 5% heavier than the Stratton 12.
Here is a comparison of how Stratton 12 and PB-1000's weights compare with the average, max and min weights in Powered Subwoofer class.

Size, drawn to scale
Both subwoofers 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 floor and pushed back to the same wall, so the bigger one visibly takes more of the room.
Near-identical footprints. SVS PB-1000 is 30mm taller.

No single best subwoofer here. Your room, where the box can physically go, and whether this is mainly for films or mainly for music will settle it long before the specs do.
| Area | Better | Why |
|---|
| Bass depth | B | SVS PB-1000 goes deeper - 19Hz against 25Hz. Under 20Hz is felt more than heard - the bottom of a pipe organ and the bottom of a film mix. |
| Amplifier power | B | SVS PB-1000 has the bigger amplifier - 300W against 200W RMS, about 1.8dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | A | KLH Stratton 12 moves more air: 12" against 10" is 1.44x the cone area, not the 1.2x the diameters suggest. More area means the same output with less excursion, and less distortion with it. |
| Enclosure | evenly matched | Both are ported designs, so they roll off in much the same way. |
| Speaker-level inputs | B | SVS PB-1000 takes a speaker-level connection as well as line level. That is what lets it work with an integrated amplifier or a vintage receiver that has no subwoofer output at all. |
| Warranty | B | SVS PB-1000 carries 5 years on parts against 2 years. A subwoofer amplifier works harder than anything else in the system, so this is not a throwaway line. |
| Price | B | SVS PB-1000 costs less - $499 against $599, about 17% less. |
A KLH Stratton 12 B SVS PB-1000
depends neither is better in the abstract - it turns on your room, your system or how you will use them. Only specs published for both subwoofers are judged; anything missing on either side is left out rather than guessed.
Which should you choose?
SVS PB-1000 is the easier recommendation: it leads on most of the measured areas and costs less. Take KLH Stratton 12 if one of the "depends" rows describes your room. Check your amplifier first: if it has no subwoofer or preamp output, SVS PB-1000 is the only one of these two you can connect at all.
One thing outweighs everything above: where the subwoofer stands. Room modes can add or remove 10dB or more at a given seat, which is far larger than any difference on this page. Before spending more, try the sub in two or three positions - the crawl test, where you put it in the listening seat and crawl the room to find where the bass sounds best, costs nothing and usually beats an upgrade.
