In this review, we will be comparing A100P and ASW610, 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 A100P 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.JBL Stage A100Pand B&W ASW610 have the same driver set up: Both subwoofers have 1 x 10" drivers.
Frequency Response
A100P has a frequency range of 35-150 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 A100P's min frequency of 35Hz.
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 A100P has a Bass reflex 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 JBL Stage A100P's and B&W ASW610's external dimensions. JBL Stage A100P has external dimensions of 359.0 x 337.0 x 435.0mm (14-1/8 x 13-1/4 x 17-1/8inch) 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).
JBL Stage A100P is clearly the larger of the two speakers. Its body is 25mm wider, 38mm taller and 41mm deeper than B&W ASW610.
Below you can see the front view size comparison of JBL Stage A100P and B&W ASW610 in scale.

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 A100P is approximately 1466.0cm2 / 227.2inch2 and base area of the B&W ASW610 is approximately 1229.3cm2 / 190.5inch2. The A100P requires 19% 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 JBL Stage A100P weighs 13.66kg / 30.1lbs and the B&W ASW610 weighs 12.55kg / 27.6lbs. This makes the A100P 9% heavier than the ASW610.
Here is a comparison of how A100P and ASW610'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 A100P needs about 19% more floor area. JBL Stage A100P stands 41mm further into the room. JBL Stage A100P is 38mm 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 | B | B&W ASW610 goes deeper - 27Hz against 35Hz. A real difference, though most music has little content below 35Hz. |
| Amplifier power | B | B&W ASW610 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 | evenly matched | Near-identical radiating area (10" against 10"). |
| Enclosure | depends | JBL Stage A100P 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 ASW610 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 ASW610 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 ASW610 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 | B&W ASW610 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 A100P costs less - $240 against $899, about 73% less. |
A JBL Stage A100P 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?
The usual trade-off: B&W ASW610 measures better, JBL Stage A100P costs about 73% 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 A100P will hit harder for the money; if it is mainly for music in a normal-sized room, B&W ASW610 is usually the easier one to make sound right. Check your amplifier first: if it has no subwoofer or preamp output, B&W ASW610 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.
