In this review, we will be comparing Concerta2 B10 and SPL-100, two Powered Subwoofer speakers from Revel and Klipsch. 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 Revel Concerta2 B10 and Klipsch SPL-100 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.Revel Concerta2 B10and Klipsch SPL-100 have the same driver set up: Both subwoofers have 1 x 10" drivers.
Frequency Response
Concerta2 B10 has a frequency range of 35-150 Hz whereas SPL-100 has a frequency range of 27-125 Hz. With a minimum frequency of 27Hz, the SPL-100 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 Revel Concerta2 B10 and Klipsch SPL-100 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 Revel Concerta2 B10's and Klipsch SPL-100's external dimensions. 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) whereas Klipsch SPL-100 has external dimensions of 418.0 x 358.0 x 478.0mm (16-7/16 x 14-1/16 x 18-13/16inch).
Klipsch SPL-100 is 19mm narrower and 2mm shorter than Revel Concerta2 B10 but it is also 38mm deeper.

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 Revel Concerta2 B10 is approximately 1658.8cm2 / 257.1inch2 and base area of the Klipsch SPL-100 is approximately 1711.2cm2 / 265.2inch2. The Concerta2 B10 requires 3% less surface area than the SPL-100 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 Revel Concerta2 B10 weighs 21.36kg / 47lbs and the Klipsch SPL-100 weighs 16.82kg / 37lbs. This makes the Concerta2 B10 27% heavier than the SPL-100.

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.
Near-identical footprints. Klipsch SPL-100 stands 38mm further into the room.

Different price classes - Revel Concerta2 B10 costs roughly 4.1x what Klipsch SPL-100 does. Before paying it, read the note below about two smaller subwoofers.
| Area | Better | Why |
|---|
| Bass depth | B | Klipsch SPL-100 goes deeper - 27Hz against 35Hz. A real difference, though most music has little content below 35Hz. |
| Amplifier power | A | Revel Concerta2 B10 has the bigger amplifier - 800W against 200W RMS, about 6dB 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 | evenly matched | Both are ported designs, so they roll off in much the same way. |
| Wireless option | depends | Only Klipsch SPL-100 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. |
| Warranty | A | Revel Concerta2 B10 carries 5 years on parts against 2 years. A subwoofer amplifier works harder than anything else in the system, so this is not a throwaway line. |
| Price | B | Klipsch SPL-100 costs less - $399 against $1,650, about 76% less. |
A Revel Concerta2 B10 B Klipsch SPL-100
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?
Revel Concerta2 B10 is ahead, but on only 1 of the measured areas, and it costs about 4.1x the price. Klipsch SPL-100 is the sensible buy unless your room is large enough to need the extra. 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 $399 each, two Klipsch SPL-100 cost about $798 against $1,650 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.
