In this review, we will be comparing T 5x 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 T 5x 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.Both REL T 5xand SVS SB-1000 Pro have a single woofer setup however the REL T 5x's woofer is 8-inch whereas the SVS SB-1000 Pro features a 12-inch woofer.
Frequency Response
T 5x has a frequency range of 32-120 Hz whereas SB-1000 Pro has a frequency range of 20-270 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 T 5x's min frequency of 32Hz.
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 REL T 5x's and SVS SB-1000 Pro's external dimensions. REL T 5x has external dimensions of 312.7 x 300.0 x 360.4mm () 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).
SVS SB-1000 Pro is clearly the larger of the two speakers. Its body is 31mm wider, 30.3mm taller and 41.6mm deeper than REL T 5x.
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 T 5x is approximately 1081.2cm2 / 167.6inch2 and base area of the SVS SB-1000 Pro is approximately 1330.6cm2 / 206.2inch2. The T 5x requires 19% less surface area than the SB-1000 Pro 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 REL T 5x weighs 14.29kg / 31.4lbs and the SVS SB-1000 Pro weighs 11.82kg / 26lbs. This makes the T 5x 21% heavier than the SB-1000 Pro.
Here is a comparison of how T 5x and SB-1000 Pro'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 23% more floor area. SVS SB-1000 Pro stands 42mm further into the room. SVS SB-1000 Pro is 30mm 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 | B | SVS SB-1000 Pro goes deeper - 20Hz against 32Hz. Under 20Hz is felt more than heard - the bottom of a pipe organ and the bottom of a film mix. |
| Amplifier power | B | 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 | B | 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. |
| Cabinet size | depends | REL T 5x is about 26% 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 | SVS SB-1000 Pro carries 5 years on parts against 3 years. A subwoofer amplifier works harder than anything else in the system, so this is not a throwaway line. |
| Price | B | SVS SB-1000 Pro costs less - $600 against $799, about 25% less. |
A REL T 5x 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?
SVS SB-1000 Pro is the easier recommendation: it leads on most of the measured areas and costs less. Take REL T 5x if one of the "depends" rows describes your room.
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.
