In this review, we will be comparing Sub 3 and ASW608, two Powered Subwoofer speakers from Dynaudio 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 Dynaudio Sub 3 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.Both Dynaudio Sub 3and B&W ASW608 have a single woofer setup however the Dynaudio Sub 3's woofer is 9.5-inch whereas the B&W ASW608 features a 8-inch woofer.
Frequency Response
Sub 3 has a frequency range of 22-175 Hz whereas ASW608 has a frequency range of 32-140 Hz. With a minimum frequency of 22Hz, the Sub 3 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
Both Dynaudio Sub 3 and B&W ASW608 have Acoustic Suspension type cabinets. 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 Dynaudio Sub 3's and B&W ASW608's external dimensions. Dynaudio Sub 3 has external dimensions of 277.0 x 269.0 x 366.0mm (10-7/8 x 10-9/16 x 14-3/8inch) 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).
Dynaudio Sub 3 is clearly the larger of the two speakers. Its body is 8mm wider, 5mm taller and 16mm deeper than B&W ASW608.

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 Dynaudio Sub 3 is approximately 984.5cm2 / 152.6inch2 and base area of the B&W ASW608 is approximately 913.5cm2 / 141.6inch2. The Sub 3 requires 8% 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 Dynaudio Sub 3 weighs 10.50kg / 23.1lbs and the B&W ASW608 weighs 8.86kg / 19.5lbs. This makes the Sub 3 19% heavier than the ASW608.
Here is a comparison of how Sub 3 and ASW608'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. Dynaudio Sub 3 stands 16mm further into the room.

Different price classes - Dynaudio Sub 3 costs roughly 2.3x what B&W ASW608 does. Before paying it, read the note below about two smaller subwoofers.
| Area | Better | Why |
|---|
| Bass depth | A | Dynaudio Sub 3 goes deeper - 22Hz against 32Hz. That gap covers the lowest notes of a five-string bass and a concert bass drum. |
| Amplifier power | A | Dynaudio Sub 3 has the bigger amplifier - 300W against 200W RMS, about 1.8dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | A | Dynaudio Sub 3 moves more air: 9.5" against 8" is 1.41x the cone area, not the 1.19x the diameters suggest. More area means the same output with less excursion, and less distortion with it. |
| Enclosure | evenly matched | Both are sealed designs, so they roll off in much the same way. |
| Speaker-level inputs | B | 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. |
| Warranty | A | Dynaudio Sub 3 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 | B&W ASW608 costs less - $599 against $1,399, about 57% less. |
A Dynaudio Sub 3 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?
The usual trade-off: Dynaudio Sub 3 measures better, B&W ASW608 costs about 57% less. In a normal room, placement will make a bigger difference than the gap between these two. 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. Two small subwoofers beat one big one in most rooms - a pair evens out the room modes in a way no single box can, whatever its specs. At $599 each, two B&W ASW608 cost about $1,198 against $1,399 for one of the other, which is worth a thought.
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.
