In this review, we will be comparing RP-1200SW and Concerta2 B10, two Powered Subwoofer speakers from Klipsch and Revel. 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 Klipsch RP-1200SW and Revel Concerta2 B10 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 Klipsch RP-1200SWand Revel Concerta2 B10 have a single woofer setup however the Klipsch RP-1200SW's woofer is 12-inch whereas the Revel Concerta2 B10 features a 10-inch woofer.
Frequency Response
RP-1200SW has a frequency range of 16.5-138 Hz whereas Concerta2 B10 has a frequency range of 35-150 Hz. With a minimum frequency of 17Hz, the RP-1200SW can go significantly deeper on the low side and provide stronger bass compared to the Concerta2 B10'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
Both Klipsch RP-1200SW and Revel Concerta2 B10 have Bass Reflex type cabinets. 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.
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 Klipsch RP-1200SW's and Revel Concerta2 B10's external dimensions. Klipsch RP-1200SW has external dimensions of 482.0 x 432.0 x 659.0mm (18-15/16inch x 17inch x 25-15/16inch) whereas Revel Concerta2 B10 has external dimensions of 420.0 x 377.0 x 440.0mm (16-1/2 x 14-13/16 x 17-5/16inch).
Klipsch RP-1200SW is clearly the larger of the two speakers. Its body is 55mm wider, 62mm taller and 219mm deeper than Revel Concerta2 B10.

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 Klipsch RP-1200SW is approximately 2846.9cm2 / 441.3inch2 and base area of the Revel Concerta2 B10 is approximately 1658.8cm2 / 257.1inch2. The RP-1200SW requires 72% more surface area than the Concerta2 B10 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 Klipsch RP-1200SW weighs 31.18kg / 68.6lbs and the Revel Concerta2 B10 weighs 21.36kg / 47lbs. This makes the RP-1200SW 46% heavier than the Concerta2 B10.
Here is a comparison of how RP-1200SW and Concerta2 B10'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.
Klipsch RP-1200SW needs about 72% more floor area. Klipsch RP-1200SW stands 219mm further into the room. Klipsch RP-1200SW is 62mm taller.

No single best subwoofer here. Your room, where the box can physically go, and whether this is mainly for films or mainly for music will settle it long before the specs do.
| Area | Better | Why |
|---|
| Bass depth | A | Klipsch RP-1200SW goes deeper - 17Hz against 35Hz. Under 20Hz is felt more than heard - the bottom of a pipe organ and the bottom of a film mix. |
| Amplifier power | B | Revel Concerta2 B10 has the bigger amplifier - 800W against 400W RMS, about 3dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | A | Klipsch RP-1200SW moves more air: 12" against 10" is 1.44x the cone area, not the 1.2x 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. |
| Wireless option | depends | Only Klipsch RP-1200SW offers a wireless link (as a paid option). It decides where the sub can go if you cannot run a cable, and is worth nothing if you can. |
| Cabinet size | depends | Revel Concerta2 B10 is about 49% 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 | Klipsch RP-1200SW costs less - $1,100 against $1,650, about 33% less. |
A Klipsch RP-1200SW B Revel Concerta2 B10
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?
Klipsch RP-1200SW has the edge on paper, though not by much. The "depends" rows are more likely to decide this than the score is. If placement is the constraint - a corner, behind a sofa, under a desk - Revel Concerta2 B10 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.
