In this review, we will be comparing Flexus Sub 100 and SB-1000 Pro, two Powered Subwoofer speakers from Klipsch 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 Klipsch Flexus Sub 100 and SVS SB-1000 Pro 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 Klipsch Flexus Sub 100and SVS SB-1000 Pro have a single woofer setup however the Klipsch Flexus Sub 100's woofer is 10-inch whereas the SVS SB-1000 Pro features a 12-inch woofer.
Frequency Response
Flexus Sub 100 has a frequency range of 26-250 Hz whereas SB-1000 Pro has a frequency range of 20-270 Hz. With a minimum frequency of 20Hz, the SB-1000 Pro can go significantly deeper on the low side and provide stronger bass compared to the Flexus Sub 100's min frequency of 26Hz.
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 Klipsch Flexus Sub 100 and SVS SB-1000 Pro have Acoustic Suspension type cabinets. Acoustic Suspension aka Sealed type subwoofers have enclosures that are sealed hence no ports or holes exists on the cabinet. Sealed designs helps to provide more accurate and tight bass responses compared to ported 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 Klipsch Flexus Sub 100's and SVS SB-1000 Pro's external dimensions. Klipsch Flexus Sub 100 has external dimensions of 340.0 x 335.0 x 349.0mm (13-3/8 x 13-3/16 x 13-3/4inch) whereas SVS SB-1000 Pro has external dimensions of 343.0 x 331.0 x 402.0mm (13-1/2inch x 13inch x 15-13/16inch).
Klipsch Flexus Sub 100 is 3mm shorter and 53mm less deeper than SVS SB-1000 Pro but it is also 4mm wider.
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 SB-1000 Pro needs about 14% more floor or shelf area. SVS SB-1000 Pro is 53mm deeper, so it stands that much further out from the wall.
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 Klipsch Flexus Sub 100 is approximately 1169.2cm2 / 181.2inch2 and base area of the SVS SB-1000 Pro is approximately 1330.6cm2 / 206.2inch2. The Flexus Sub 100 requires 12% less surface area than the SB-1000 Pro 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 Klipsch Flexus Sub 100 weighs 9.40kg / 20.7lbs and the SVS SB-1000 Pro weighs 11.82kg / 26lbs. This makes the SB-1000 Pro 26% heavier than the Flexus Sub 100.
Here is a comparison of how Flexus Sub 100 and SB-1000 Pro's weights compare with the average, max and min weights in Powered Subwoofer class.

Different price classes - SVS SB-1000 Pro costs roughly 1.7x what Klipsch Flexus Sub 100 does. Before paying it, read the note below about two smaller subwoofers.
| Area | Better | Why |
|---|
| Bass depth | B | SVS SB-1000 Pro goes deeper - 20Hz against 26Hz. Under 20Hz is felt more than heard - the bottom of a pipe organ and the bottom of a film mix. |
| Amplifier power | B | SVS SB-1000 Pro has the bigger amplifier - 325W against 80W RMS, about 6.1dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | B | SVS SB-1000 Pro 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 sealed designs, so they roll off in much the same way. |
| Price | A | Klipsch Flexus Sub 100 costs less - $350 against $600, about 42% less. |
A Klipsch Flexus Sub 100 B SVS SB-1000 Pro
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?
The usual trade-off: SVS SB-1000 Pro measures better, Klipsch Flexus Sub 100 costs about 42% less. In a normal room, placement will make a bigger difference than the gap between these two. Two small subwoofers beat one big one in most rooms - a pair evens out the room modes in a way no single box can, whatever its specs. At $350 each, two Klipsch Flexus Sub 100 cost about $700 against $600 for one of the other, which is worth a thought.
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.
