In this review, we will be comparing SubSeries 250 and R-100SW, two Powered Subwoofer speakers from PSB and Klipsch. 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 PSB SubSeries 250 and Klipsch R-100SW 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.PSB SubSeries 250and Klipsch R-100SW have the same driver set up: Both subwoofers have 1 x 10" drivers.
Frequency Response
SubSeries 250 has a frequency range of 25-150 Hz whereas R-100SW has a frequency range of 32-120 Hz. With a minimum frequency of 25Hz, the SubSeries 250 can go significantly deeper on the low side and provide stronger bass compared to the R-100SW's min frequency of 32Hz.
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
The PSB SubSeries 250 has a Acoustic Suspension type cabinet. 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. On the other hand the Klipsch R-100SW have Bass reflex type enclosure.
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 PSB SubSeries 250's and Klipsch R-100SW's external dimensions. PSB SubSeries 250 has external dimensions of 362.0 x 348.0 x 397.0mm (14-1/4 x 13-11/16 x 15-5/8inch) whereas Klipsch R-100SW has external dimensions of 372.0 x 320.0 x 459.0mm (14-5/8 x 12-9/16 x 18-1/16inch).
PSB SubSeries 250 is 10mm shorter and 62mm less deeper than Klipsch R-100SW but it is also 28mm 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 PSB SubSeries 250 is approximately 1381.6cm2 / 214.1inch2 and base area of the Klipsch R-100SW is approximately 1468.8cm2 / 227.7inch2. The SubSeries 250 requires 6% less surface area than the R-100SW 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 PSB SubSeries 250 weighs 19.09kg / 42lbs and the Klipsch R-100SW weighs 10.91kg / 24lbs. This makes the SubSeries 250 75% heavier than the R-100SW.
Here is a comparison of how SubSeries 250 and R-100SW'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. Klipsch R-100SW stands 62mm further into the room.

A sealed subwoofer against a ported one. That is the most consequential line on this page: it decides how the bass rolls off, how it behaves in a small room, and how much output you get for the size of the box.
| Area | Better | Why |
|---|
| Bass depth | A | PSB SubSeries 250 goes deeper - 25Hz against 32Hz. That gap covers the lowest notes of a five-string bass and a concert bass drum. |
| Amplifier power | A | PSB SubSeries 250 has the bigger amplifier - 200W against 150W RMS, about 1.2dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | evenly matched | Near-identical radiating area (10" against 10"). |
| Enclosure | depends | PSB SubSeries 250 is sealed - a sealed box rolls off gently and is usually the easier one to integrate in a small or awkward room; Klipsch R-100SW is ported - a ported box gives more output low down for its size, at the cost of a steeper roll-off below tuning. Neither is better in the abstract; ported tends to suit films and sealed tends to suit music, and both generalisations have exceptions. |
| Speaker-level inputs | A | PSB SubSeries 250 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. |
| Wireless option | depends | Only PSB SubSeries 250 offers a wireless link (as a paid option). It decides where the sub can go if you cannot run a cable, and is worth nothing if you can. |
| Warranty | B | Klipsch R-100SW carries 2 years on parts against 1 years. A subwoofer amplifier works harder than anything else in the system, so this is not a throwaway line. |
| Price | B | Klipsch R-100SW costs less - $275 against $999, about 72% less. |
A PSB SubSeries 250 B Klipsch R-100SW
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: PSB SubSeries 250 measures better, Klipsch R-100SW costs about 72% less. In a normal room, placement will make a bigger difference than the gap between these two. Films or music? If this is mainly a home cinema, Klipsch R-100SW will hit harder for the money; if it is mainly for music in a normal-sized room, PSB SubSeries 250 is usually the easier one to make sound right. Check your amplifier first: if it has no subwoofer or preamp output, PSB SubSeries 250 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.
