In this review, we will be comparing Stage 200P and ASW608, two Powered Subwoofer speakers from JBL 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 JBL Stage 200P 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 JBL Stage 200Pand B&W ASW608 have a single woofer setup however the JBL Stage 200P's woofer is 10-inch whereas the B&W ASW608 features a 8-inch woofer.
Frequency Response
Stage 200P has a frequency range of 32-150 Hz whereas ASW608 has a frequency range of 32-140 Hz.
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 JBL Stage 200P has a Passive Radiator type cabinet. Passive Radiator type subwoofers sports a non-powered cone that moves in response to the main woofer to move air out in order to generate stronger bass in a smaller body compared to ported or sealed designs. 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 JBL Stage 200P's and B&W ASW608's external dimensions. JBL Stage 200P has external dimensions of 362.0 x 351.0 x 388.0mm (14-1/4inch x 13-13/16inch x 15-1/4inch) 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).
JBL Stage 200P is clearly the larger of the two speakers. Its body is 90mm wider, 90mm taller and 38mm 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 JBL Stage 200P is approximately 1361.9cm2 / 211.1inch2 and base area of the B&W ASW608 is approximately 913.5cm2 / 141.6inch2. The Stage 200P requires 49% 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 JBL Stage 200P weighs 14.45kg / 31.8lbs and the B&W ASW608 weighs 8.86kg / 19.5lbs. This makes the Stage 200P 63% heavier than the ASW608.
Here is a comparison of how Stage 200P 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.
JBL Stage 200P needs about 49% more floor area. JBL Stage 200P stands 38mm further into the room. JBL Stage 200P is 90mm 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 (32Hz vs 32Hz). |
| Amplifier power | B | B&W ASW608 has the bigger amplifier - 200W against 150W RMS, about 1.2dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | A | JBL Stage 200P moves more air: 10" against 8" is 1.56x the cone area, not the 1.25x the diameters suggest. More area means the same output with less excursion, and less distortion with it. |
| Enclosure | depends | JBL Stage 200P 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 ASW608 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 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. |
| Cabinet size | depends | B&W ASW608 is about 50% 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 | B&W ASW608 carries 2 years on parts against 1 years. A subwoofer amplifier works harder than anything else in the system, so this is not a throwaway line. |
| Price | A | JBL Stage 200P costs less - $499 against $599, about 17% less. |
A JBL Stage 200P 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: B&W ASW608 measures better, JBL Stage 200P costs about 17% 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, JBL Stage 200P 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.
