In this review, we will be comparing Airmotiv XS12e and A120P, two Powered Subwoofer speakers from Emotiva and JBL. 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 Emotiva Airmotiv XS12e and JBL Stage A120P 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.Emotiva Airmotiv XS12eand JBL Stage A120P have the same driver set up: Both subwoofers have 1 x 12" drivers.
Frequency Response
Airmotiv XS12e has a frequency range of 28-200 Hz whereas A120P has a frequency range of 32-150 Hz. With a minimum frequency of 28Hz, the Airmotiv XS12e can go slightly deeper then the A120P'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 Emotiva Airmotiv XS12e has a Bass Reflex type cabinet. 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. On the other hand the JBL Stage A120P have Bass reflex type enclosure.
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 Emotiva Airmotiv XS12e's and JBL Stage A120P's external dimensions. Emotiva Airmotiv XS12e has external dimensions of 400.0 x 400.0 x 400.0mm (15-3/4 x 15-3/4 x 15-3/4inch) whereas JBL Stage A120P has external dimensions of 415.0 x 393.0 x 475.0mm (16-5/16 x 15-7/16 x 18-11/16inch).
Emotiva Airmotiv XS12e is 15mm shorter and 75mm less deeper than JBL Stage A120P but it is also 7mm wider.
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.
JBL Stage A120P needs about 17% more floor or shelf area. JBL Stage A120P is 75mm deeper, so it stands that much further out from the wall. JBL Stage A120P is 15mm 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 Emotiva Airmotiv XS12e is approximately 1600.0cm2 / 248.0inch2 and base area of the JBL Stage A120P is approximately 1866.8cm2 / 289.4inch2. The Airmotiv XS12e requires 14% less surface area than the A120P 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 Emotiva Airmotiv XS12e weighs 19.05kg / 41.9lbs and the JBL Stage A120P weighs 18.68kg / 41.1lbs. This makes the Airmotiv XS12e 2% heavier than the A120P.
Here is a comparison of how Airmotiv XS12e and A120P's weights compare with the average, max and min weights in Powered Subwoofer class.

Different price classes - Emotiva Airmotiv XS12e costs roughly 2.3x what JBL Stage A120P does. Before paying it, read the note below about two smaller subwoofers.
| Area | Better | Why |
|---|
| Bass depth | A | Emotiva Airmotiv XS12e goes deeper - 28Hz against 32Hz. A real difference, though most music has little content below 32Hz. |
| Amplifier power | evenly matched | Much the same amplifier (300W vs 250W RMS) - under 1dB apart. |
| Driver area | evenly matched | Near-identical radiating area (12" against 12"). |
| Enclosure | evenly matched | Both are ported designs, so they roll off in much the same way. |
| Cabinet size | depends | Emotiva Airmotiv XS12e is about 17% 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 | Emotiva Airmotiv XS12e carries 5 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 | B | JBL Stage A120P costs less - $300 against $699, about 57% less. |
A Emotiva Airmotiv XS12e B JBL Stage A120P
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: Emotiva Airmotiv XS12e measures better, JBL Stage A120P costs about 57% less. In a normal room, placement will make a bigger difference than the gap between these two. 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 $300 each, two JBL Stage A120P cost about $600 against $699 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.
