In this review, we will be comparing Q SUB100 and ASW610, two Powered Subwoofer speakers from Q Acoustics 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 Q Acoustics Q SUB100 and B&W ASW610 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.Q Acoustics Q SUB100and B&W ASW610 have the same driver set up: Both subwoofers have 1 x 10" drivers.
Frequency Response
Q SUB100 has a frequency range of 32-250 Hz whereas ASW610 has a frequency range of 27-140 Hz. With a minimum frequency of 27Hz, the ASW610 can go significantly deeper on the low side and provide stronger bass compared to the Q SUB100'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 Q Acoustics Q SUB100 has a Infinite Baffle type cabinet. On the other hand the B&W ASW610 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 Q Acoustics Q SUB100's and B&W ASW610's external dimensions. Q Acoustics Q SUB100 has external dimensions of 350.0 x 350.0 x 382.0mm (13-3/4 x 13-3/4 x 15-1/16inch) whereas B&W ASW610 has external dimensions of 321.0 x 312.0 x 394.0mm (12-5/8 x 12-1/4 x 15-1/2inch).
B&W ASW610 is 38mm narrower and 29mm shorter than Q Acoustics Q SUB100 but it is also 12mm deeper.
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.
Q Acoustics Q SUB100 needs about 9% more floor or shelf area. Q Acoustics Q SUB100 is 29mm 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 Q Acoustics Q SUB100 is approximately 1337.0cm2 / 207.2inch2 and base area of the B&W ASW610 is approximately 1229.3cm2 / 190.5inch2. The Q SUB100 requires 9% more surface area than the ASW610 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 Q Acoustics Q SUB100 weighs 16.70kg / 36.7lbs and the B&W ASW610 weighs 12.55kg / 27.6lbs. This makes the Q SUB100 33% heavier than the ASW610.
Here is a comparison of how Q SUB100 and ASW610's weights compare with the average, max and min weights in Powered Subwoofer class.

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 | B&W ASW610 goes deeper - 27Hz against 32Hz. A real difference, though most music has little content below 32Hz. |
| Amplifier power | A | Q Acoustics Q SUB100 has the bigger amplifier - 250W against 200W RMS, about 1dB 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 | evenly matched | Both are sealed designs, so they roll off in much the same way. |
| Warranty | A | Q Acoustics Q SUB100 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 | A | Q Acoustics Q SUB100 costs less - $699 against $899, about 22% less. |
A Q Acoustics Q SUB100 B B&W ASW610
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?
Q Acoustics Q SUB100 has the edge on paper, though not by much. The "depends" rows are more likely to decide this than the score is.
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.
