In this review, we will be comparing SPL-100 and ASW610XP, two Powered Subwoofer speakers from Klipsch and Bowers Wilkins. 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 SPL-100 and B&W ASW610XP 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.Klipsch SPL-100and B&W ASW610XP have the same driver set up: Both subwoofers have 1 x 10" drivers.
Frequency Response
SPL-100 has a frequency range of 27-125 Hz whereas ASW610XP has a frequency range of 25-140 Hz. With a minimum frequency of 25Hz, the ASW610XP can go slightly deeper then the SPL-100's min frequency of 27Hz.
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 Klipsch SPL-100 has a Bass Reflex type cabinet. 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. On the other hand the B&W ASW610XP have Acoustic Suspension type enclosure. 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 SPL-100's and B&W ASW610XP's external dimensions. Klipsch SPL-100 has external dimensions of 418.0 x 358.0 x 478.0mm (16-7/16 x 14-1/16 x 18-13/16inch) whereas B&W ASW610XP has external dimensions of 337.0 x 328.0 x 410.0mm (13-1/4 x 12-7/8 x 16-1/8inch).
Klipsch SPL-100 is clearly the larger of the two speakers. Its body is 30mm wider, 81mm taller and 68mm deeper than B&W ASW610XP.

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 SPL-100 is approximately 1711.2cm2 / 265.2inch2 and base area of the B&W ASW610XP is approximately 1344.8cm2 / 208.4inch2. The SPL-100 requires 27% more surface area than the ASW610XP which gives it a small disadvantage 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 SPL-100 weighs 16.82kg / 37lbs and the B&W ASW610XP weighs 18.69kg / 41.1lbs. This makes the ASW610XP 11% heavier than the SPL-100.
Here is a comparison of how SPL-100 and ASW610XP'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.
Klipsch SPL-100 needs about 27% more floor area. Klipsch SPL-100 stands 68mm further into the room. Klipsch SPL-100 is 81mm taller.

A ported subwoofer against a sealed 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 | evenly matched | Effectively the same reach (27Hz vs 25Hz). |
| Amplifier power | B | B&W ASW610XP has the bigger amplifier - 500W against 200W RMS, about 4dB 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 | Klipsch SPL-100 is ported - a ported box gives more output low down for its size, at the cost of a steeper roll-off below tuning; B&W ASW610XP is sealed - a sealed box rolls off gently and is usually the easier one to integrate in a small or awkward room. 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 | B | B&W ASW610XP 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 Klipsch SPL-100 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. |
| Cabinet size | depends | B&W ASW610XP is about 37% smaller by volume. In a subwoofer that is a real trade rather than a preference: box volume is how you get output low down without a bigger amplifier. |
| Price | A | Klipsch SPL-100 costs less - $399 against $1,799, about 78% less. |
A Klipsch SPL-100 B B&W ASW610XP
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: B&W ASW610XP measures better, Klipsch SPL-100 costs about 78% 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 SPL-100 will hit harder for the money; if it is mainly for music in a normal-sized room, B&W ASW610XP is usually the easier one to make sound right. Check your amplifier first: if it has no subwoofer or preamp output, B&W ASW610XP 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.
