In this review, we will be comparing ASW608 and S8, two Powered Subwoofer speakers from Bowers Wilkins and Audioengine. 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 B&W ASW608 and Audioengine S8 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.B&W ASW608and Audioengine S8 have the same driver set up: Both subwoofers have 1 x 8" drivers.
Frequency Response
ASW608 has a frequency range of 32-140 Hz whereas S8 has a frequency range of 27-180 Hz. With a minimum frequency of 27Hz, the S8 can go significantly deeper on the low side and provide stronger bass compared to the ASW608'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 B&W ASW608 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 Audioengine S8 have Bass Reflex type enclosure. 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.
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 B&W ASW608's and Audioengine S8's external dimensions. 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) whereas Audioengine S8 has external dimensions of 334.0 x 293.0 x 337.0mm (13-1/8 x 11-1/2 x 13-1/4inch).
B&W ASW608 is 32mm narrower and 62mm shorter than Audioengine S8 but it is also 13mm deeper.

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 B&W ASW608 is approximately 913.5cm2 / 141.6inch2 and base area of the Audioengine S8 is approximately 987.4cm2 / 153.0inch2. The ASW608 requires 7% less surface area than the S8 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 B&W ASW608 weighs 8.86kg / 19.5lbs and the Audioengine S8 weighs 13.64kg / 30lbs. This makes the S8 54% heavier than the ASW608.
Here is a comparison of how ASW608 and S8'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.
Audioengine S8 needs about 8% more floor area. Audioengine S8 is 62mm taller.

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 | B | Audioengine S8 goes deeper - 27Hz against 32Hz. A real difference, though most music has little content below 32Hz. |
| Amplifier power | A | B&W ASW608 has the bigger amplifier - 200W against 125W RMS, about 2dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | evenly matched | Near-identical radiating area (8" against 8"). |
| Enclosure | depends | B&W ASW608 is sealed - a sealed box rolls off gently and is usually the easier one to integrate in a small or awkward room; Audioengine S8 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 | B&W ASW608 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. |
| Driver placement | depends | B&W ASW608 fires front and Audioengine S8 fires down. A down-firing driver is more forgiving of a grille-less look and of a hard floor; a front-firing one is the safer choice on a thick carpet or a suspended timber floor. |
| Cabinet size | depends | B&W ASW608 is about 25% 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 | B | Audioengine S8 carries 3 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 | B | Audioengine S8 costs less - $349 against $599, about 42% less. |
A B&W ASW608 B Audioengine S8
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. Films or music? If this is mainly a home cinema, Audioengine S8 will hit harder for the money; if it is mainly for music in a normal-sized room, B&W ASW608 is usually the easier one to make sound right. Check your amplifier first: if it has no subwoofer or preamp output, B&W ASW608 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.
