In this review, we will be comparing SB-1000 Pro and SUB8, two Powered Subwoofer speakers from SVS and Kanto. 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 SVS SB-1000 Pro and Kanto SUB8 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 SVS SB-1000 Proand Kanto SUB8 have a single woofer setup however the SVS SB-1000 Pro's woofer is 12-inch whereas the Kanto SUB8 features a 8-inch woofer.
Frequency Response
SB-1000 Pro has a frequency range of 20-270 Hz whereas SUB8 has a frequency range of 35-175 Hz. With a minimum frequency of 20Hz, the SB-1000 Pro can go significantly deeper on the low side and provide stronger bass compared to the SUB8'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 SVS SB-1000 Pro and Kanto SUB8 have Acoustic Suspension type cabinets. 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 SVS SB-1000 Pro's and Kanto SUB8's external dimensions. SVS SB-1000 Pro has external dimensions of 343.0 x 331.0 x 402.0mm (13-1/2inch x 13inch x 15-13/16inch) whereas Kanto SUB8 has external dimensions of 301.0 x 281.0 x 329.0mm (11-13/16 x 11-1/16 x 12-15/16inch).
SVS SB-1000 Pro is clearly the larger of the two speakers. Its body is 50mm wider, 42mm taller and 73mm deeper than Kanto SUB8.
Below you can see the front view size comparison of SVS SB-1000 Pro and Kanto SUB8 in scale.

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 SVS SB-1000 Pro is approximately 1330.6cm2 / 206.2inch2 and base area of the Kanto SUB8 is approximately 924.5cm2 / 143.3inch2. The SB-1000 Pro requires 44% more surface area than the SUB8 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 SVS SB-1000 Pro weighs 11.82kg / 26lbs and the Kanto SUB8 weighs 7.82kg / 17.2lbs. This makes the SB-1000 Pro 51% heavier than the SUB8.
Here is a comparison of how SB-1000 Pro and SUB8'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.
SVS SB-1000 Pro needs about 44% more floor area. SVS SB-1000 Pro stands 73mm further into the room. SVS SB-1000 Pro is 42mm taller.

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 | A | SVS SB-1000 Pro goes deeper - 20Hz against 35Hz. Under 20Hz is felt more than heard - the bottom of a pipe organ and the bottom of a film mix. |
| Amplifier power | A | SVS SB-1000 Pro has the bigger amplifier - 325W against 125W RMS, about 4.1dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | A | SVS SB-1000 Pro 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 sealed designs, so they roll off in much the same way. |
| Speaker-level inputs | A | SVS SB-1000 Pro 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. |
| Wireless option | depends | Only SVS SB-1000 Pro 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 | Kanto SUB8 is about 39% 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 | SVS SB-1000 Pro 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 | Kanto SUB8 costs less - $300 against $600, about 50% less. |
A SVS SB-1000 Pro B Kanto SUB8
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: SVS SB-1000 Pro measures better, Kanto SUB8 costs about 50% less. In a normal room, placement will make a bigger difference than the gap between these two. Check your amplifier first: if it has no subwoofer or preamp output, SVS SB-1000 Pro is the only one of these two you can connect at all. 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 SUB8 cost about $600 against $600 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.
