In this review, we will be comparing RP-1200SW and SUB3070, two Powered Subwoofer speakers from Klipsch and ELAC. 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 ELAC SUB3070 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.Klipsch RP-1200SWand ELAC SUB3070 have the same driver set up: Both subwoofers have 1 x 12" drivers.
Frequency Response
RP-1200SW has a frequency range of 16.5-138 Hz whereas SUB3070 has a frequency range of 18-180 Hz. With a minimum frequency of 17Hz, the RP-1200SW can go slightly deeper then the SUB3070's min frequency of 18Hz.
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 Klipsch RP-1200SW 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 ELAC SUB3070 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 Klipsch RP-1200SW's and ELAC SUB3070'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 ELAC SUB3070 has external dimensions of 435.0 x 520.0 x 477.0mm (17-1/8 x 20-7/16 x 18-3/4inch).
ELAC SUB3070 is 47mm shorter and 182mm less deeper than Klipsch RP-1200SW but it is also 88mm 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.
Klipsch RP-1200SW needs about 15% more floor or shelf area. Klipsch RP-1200SW is 182mm deeper, so it stands that much further out from the wall. Klipsch RP-1200SW 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 Klipsch RP-1200SW is approximately 2846.9cm2 / 441.3inch2 and base area of the ELAC SUB3070 is approximately 2480.4cm2 / 384.5inch2. The RP-1200SW requires 15% more surface area than the SUB3070 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 ELAC SUB3070 weighs 35.00kg / 77lbs. This makes the SUB3070 12% heavier than the RP-1200SW.
Here is a comparison of how RP-1200SW and SUB3070's weights compare with the average, max and min weights in Powered Subwoofer class.

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 | evenly matched | Effectively the same reach (17Hz vs 18Hz). |
| Amplifier power | B | ELAC SUB3070 has the bigger amplifier - 1200W against 400W RMS, about 4.8dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | evenly matched | Near-identical radiating area (12" against 12"). |
| Enclosure | depends | Klipsch RP-1200SW is ported - a ported box gives more output low down for its size, at the cost of a steeper roll-off below tuning; ELAC SUB3070 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 | ELAC SUB3070 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. |
| Driver placement | depends | Klipsch RP-1200SW fires front and ELAC SUB3070 fires side. A down-firing driver is more forgiving of a grille-less look and of a hard floor; a front-firing one is the safer choice on a thick carpet or a suspended timber floor. |
| Cabinet size | depends | ELAC SUB3070 is about 21% 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 | Klipsch RP-1200SW 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 | ELAC SUB3070 costs less - $999 against $1,100, about 9% less. |

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?
ELAC SUB3070 has the edge on paper, though not by much. The "depends" rows are more likely to decide this than the score is. Films or music? If this is mainly a home cinema, Klipsch RP-1200SW will hit harder for the money; if it is mainly for music in a normal-sized room, ELAC SUB3070 is usually the easier one to make sound right. Check your amplifier first: if it has no subwoofer or preamp output, ELAC SUB3070 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.
