In this review, we will be comparing CR8SBT and A120P, two Powered Subwoofer speakers from Mackie 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 Mackie CR8SBT 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.Both Mackie CR8SBTand JBL Stage A120P have a single woofer setup however the Mackie CR8SBT's woofer is 8-inch whereas the JBL Stage A120P features a 12-inch woofer.
Frequency Response
CR8SBT has a frequency range of 37-400 Hz whereas A120P has a frequency range of 32-150 Hz. With a minimum frequency of 32Hz, the A120P can go significantly deeper on the low side and provide stronger bass compared to the CR8SBT's min frequency of 37Hz.
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.

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 Mackie CR8SBT's and JBL Stage A120P's external dimensions. Mackie CR8SBT has external dimensions of 368.3 x 322.3 x 457.2mm () 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).
JBL Stage A120P is clearly the larger of the two speakers. Its body is 70.7mm wider, 46.7mm taller and 17.8mm deeper than Mackie CR8SBT.
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 27% more floor or shelf area. JBL Stage A120P is 18mm deeper, so it stands that much further out from the wall. JBL Stage A120P is 47mm 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 Mackie CR8SBT is approximately 1473.6cm2 / 228.4inch2 and base area of the JBL Stage A120P is approximately 1866.8cm2 / 289.4inch2. The CR8SBT requires 21% 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 Mackie CR8SBT weighs 11.52kg / 25.3lbs and the JBL Stage A120P weighs 18.68kg / 41.1lbs. This makes the A120P 62% heavier than the CR8SBT.
Here is a comparison of how CR8SBT and A120P's weights compare with the average, max and min weights in Powered Subwoofer class.

Two quite different sizes of subwoofer. Room volume decides this more than anything else on the page: a big driver in a small room is wasted, and a small one in a large room is worked to death.
| Area | Better | Why |
|---|
| Bass depth | B | JBL Stage A120P goes deeper - 32Hz against 37Hz. A real difference, though most music has little content below 37Hz. |
| Amplifier power | B | JBL Stage A120P has the bigger amplifier - 250W against 100W RMS, about 4dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | B | JBL Stage A120P moves more air: 12" against 8" is 2.25x the cone area, not the 1.5x the diameters suggest. More area means the same output with less excursion, and less distortion with it. |
| Enclosure | evenly matched | Both are ported designs, so they roll off in much the same way. |
| Cabinet size | depends | Mackie CR8SBT is about 30% 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. |
| Price | A | Mackie CR8SBT costs less - $200 against $300, about 33% less. |
A Mackie CR8SBT 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: JBL Stage A120P measures better, Mackie CR8SBT costs about 33% less. In a normal room, placement will make a bigger difference than the gap between these two. If placement is the constraint - a corner, behind a sofa, under a desk - Mackie CR8SBT is the one that will actually go there, and a well-placed small subwoofer beats a badly-placed big one every time.
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.
