In this review, we will be comparing SUB6 and RP-1200SW, two Powered Subwoofer speakers from Kanto 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 Kanto SUB6 and Klipsch RP-1200SW 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 Kanto SUB6and Klipsch RP-1200SW have a single woofer setup however the Kanto SUB6's woofer is 6-inch whereas the Klipsch RP-1200SW features a 12-inch woofer.
Frequency Response
SUB6 has a frequency range of 35-165 Hz whereas RP-1200SW has a frequency range of 16.5-138 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 SUB6'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.

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 Kanto SUB6's and Klipsch RP-1200SW's external dimensions. Kanto SUB6 has external dimensions of 241.3 x 222.3 x 266.7mm () whereas Klipsch RP-1200SW has external dimensions of 482.0 x 432.0 x 659.0mm (18-15/16inch x 17inch x 25-15/16inch).
Klipsch RP-1200SW is clearly the larger of the two speakers. Its body is 209.7mm wider, 240.7mm taller and 392.3mm deeper than Kanto SUB6.
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 380% more floor or shelf area. Klipsch RP-1200SW is 392mm deeper, so it stands that much further out from the wall. Klipsch RP-1200SW is 241mm 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 Kanto SUB6 is approximately 592.9cm2 / 91.9inch2 and base area of the Klipsch RP-1200SW is approximately 2846.9cm2 / 441.3inch2. The SUB6 requires 79% less surface area than the RP-1200SW 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 Kanto SUB6 weighs 5.31kg / 11.7lbs and the Klipsch RP-1200SW weighs 31.18kg / 68.6lbs. This makes the RP-1200SW 487% heavier than the SUB6.
Here is a comparison of how SUB6 and RP-1200SW's weights compare with the average, max and min weights in Powered Subwoofer class.

A sealed subwoofer against a ported 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 | B | 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 | Klipsch RP-1200SW has the bigger amplifier - 400W against 100W RMS, about 6dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | B | Klipsch RP-1200SW moves more air: 12" against 6" is 4x the cone area, not the 2x the diameters suggest. More area means the same output with less excursion, and less distortion with it. |
| Enclosure | depends | Kanto SUB6 is sealed - a sealed box rolls off gently and is usually the easier one to integrate in a small or awkward room; 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. Neither is better in the abstract; ported tends to suit films and sealed tends to suit music, and both generalisations have exceptions. |
| Cabinet size | depends | Kanto SUB6 is about 90% 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 | B | Klipsch RP-1200SW 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 | A | Kanto SUB6 costs less - $300 against $1,100, about 73% less. |
A Kanto SUB6 B Klipsch RP-1200SW
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: Klipsch RP-1200SW measures better, Kanto SUB6 costs about 73% less. In a normal room, placement will make a bigger difference than the gap between these two. 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, Kanto SUB6 is usually the easier one to make sound right. 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 Kanto SUB6 cost about $600 against $1,100 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.
