In this review, we will be comparing No.35 and SB-1000 Pro, two Powered Subwoofer speakers from REL and SVS. 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 REL No.35 and SVS SB-1000 Pro 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.REL No.35and SVS SB-1000 Pro have the same driver set up: Both subwoofers have 1 x 12" drivers.
Frequency Response
No.35 has a frequency range of 17 Hz (-6dB, in room) whereas SB-1000 Pro has a frequency range of 20-270 Hz. With a minimum frequency of 17Hz, the No.35 can go slightly deeper then the SB-1000 Pro's min frequency of 20Hz.
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 REL No.35 has a Sealed type cabinet. On the other hand the SVS SB-1000 Pro 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 REL No.35's and SVS SB-1000 Pro's external dimensions. REL No.35 has external dimensions of 435.0 x 638.0 x 724.0mm (17-1/8 x 25-1/8 x 28-1/2inch) whereas 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).
REL No.35 is clearly the larger of the two speakers. Its body is 307mm wider, 92mm taller and 322mm deeper than SVS SB-1000 Pro.
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.
REL No.35 needs about 247% more floor or shelf area. REL No.35 is 322mm deeper, so it stands that much further out from the wall. REL No.35 is 92mm 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 REL No.35 is approximately 4619.1cm2 / 716.0inch2 and base area of the SVS SB-1000 Pro is approximately 1330.6cm2 / 206.2inch2. The No.35 requires 247% more surface area than the SB-1000 Pro 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 REL No.35 weighs 59.00kg / 129.8lbs and the SVS SB-1000 Pro weighs 11.82kg / 26lbs. This makes the No.35 399% heavier than the SB-1000 Pro.
Here is a comparison of how No.35 and SB-1000 Pro's weights compare with the average, max and min weights in Powered Subwoofer class.

Different price classes - REL No.35 costs roughly 16.7x what SVS SB-1000 Pro does. Before paying it, read the note below about two smaller subwoofers.
| Area | Better | Why |
|---|
| Bass depth | A | REL No.35 goes deeper - 17Hz against 20Hz. Under 20Hz is felt more than heard - the bottom of a pipe organ and the bottom of a film mix. |
| Amplifier power | A | REL No.35 has the bigger amplifier - 900W against 325W RMS, about 4.4dB 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 | evenly matched | Both are sealed designs, so they roll off in much the same way. |
| Cabinet size | depends | SVS SB-1000 Pro is about 77% 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 | B | SVS SB-1000 Pro costs less - $600 against $10,000, about 94% less. |
A REL No.35 B SVS SB-1000 Pro
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: REL No.35 measures better, SVS SB-1000 Pro costs about 94% less. In a normal room, placement will make a bigger difference than the gap between these two. 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 $600 each, two SVS SB-1000 Pro cost about $1,200 against $10,000 for one of the other, which is worth a thought. If placement is the constraint - a corner, behind a sofa, under a desk - SVS SB-1000 Pro 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.
