In this review, we will be comparing Q SUB80 and ASW608, 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 SUB80 and B&W ASW608 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 SUB80and B&W ASW608 have the same driver set up: Both subwoofers have 1 x 8" drivers.
Frequency Response
Q SUB80 has a frequency range of 36-250 Hz whereas ASW608 has a frequency range of 32-140 Hz. With a minimum frequency of 32Hz, the ASW608 can go slightly deeper then the Q SUB80's min frequency of 36Hz.
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 SUB80 has a Infinite Baffle type cabinet. On the other hand the B&W ASW608 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 SUB80's and B&W ASW608's external dimensions. Q Acoustics Q SUB80 has external dimensions of 315.0 x 315.0 x 347.0mm (12-3/8 x 12-3/8 x 13-11/16inch) whereas B&W ASW608 has external dimensions of 272.0 x 261.0 x 350.0mm (10-11/16 x 10-1/4 x 13-3/4inch).
B&W ASW608 is 54mm narrower and 43mm shorter than Q Acoustics Q SUB80 but it is also 3mm 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 SUB80 needs about 20% more floor or shelf area. Q Acoustics Q SUB80 is 43mm 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 SUB80 is approximately 1093.1cm2 / 169.4inch2 and base area of the B&W ASW608 is approximately 913.5cm2 / 141.6inch2. The Q SUB80 requires 20% more surface area than the ASW608 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 SUB80 weighs 15.00kg / 33lbs and the B&W ASW608 weighs 8.86kg / 19.5lbs. This makes the Q SUB80 69% heavier than the ASW608.
Here is a comparison of how Q SUB80 and ASW608'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 ASW608 goes deeper - 32Hz against 36Hz. A real difference, though most music has little content below 36Hz. |
| Amplifier power | evenly matched | Much the same amplifier (200W vs 200W RMS) - under 1dB apart. |
| Driver area | evenly matched | Near-identical radiating area (8" against 8"). |
| Enclosure | evenly matched | Both are sealed designs, so they roll off in much the same way. |
| Cabinet size | depends | B&W ASW608 is about 28% 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. |
| Warranty | A | Q Acoustics Q SUB80 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 | evenly matched | Priced within a few per cent of each other. |
A Q Acoustics Q SUB80 B B&W ASW608
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?
Neither runs away with it - they trade advantages. Let your room size and where the box can actually stand settle it.
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.
