In this review, we will be comparing SB-1000 Pro and Sub 3, two Powered Subwoofer speakers from SVS and Dynaudio. 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 Dynaudio Sub 3 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 Dynaudio Sub 3 have a single woofer setup however the SVS SB-1000 Pro's woofer is 12-inch whereas the Dynaudio Sub 3 features a 9.5-inch woofer.
Frequency Response
SB-1000 Pro has a frequency range of 20-270 Hz whereas Sub 3 has a frequency range of 22-175 Hz. With a minimum frequency of 20Hz, the SB-1000 Pro can go slightly deeper then the Sub 3's min frequency of 22Hz.
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 Dynaudio Sub 3 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 Dynaudio Sub 3'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 Dynaudio Sub 3 has external dimensions of 277.0 x 269.0 x 366.0mm (10-7/8 x 10-9/16 x 14-3/8inch).
SVS SB-1000 Pro is clearly the larger of the two speakers. Its body is 62mm wider, 66mm taller and 36mm deeper than Dynaudio Sub 3.
Below you can see the front view size comparison of SVS SB-1000 Pro and Dynaudio Sub 3 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 Dynaudio Sub 3 is approximately 984.5cm2 / 152.6inch2. The SB-1000 Pro requires 35% more surface area than the Sub 3 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 Dynaudio Sub 3 weighs 10.50kg / 23.1lbs. This makes the SB-1000 Pro 13% heavier than the Sub 3.
Here is a comparison of how SB-1000 Pro and Sub 3'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 35% more floor area. SVS SB-1000 Pro stands 36mm further into the room. SVS SB-1000 Pro is 66mm taller.

Different price classes - Dynaudio Sub 3 costs roughly 2.3x what SVS SB-1000 Pro does. Before paying it, read the note below about two smaller subwoofers.
| Area | Better | Why |
|---|
| Bass depth | evenly matched | Effectively the same reach (20Hz vs 22Hz). |
| Amplifier power | evenly matched | Much the same amplifier (325W vs 300W RMS) - under 1dB apart. |
| Driver area | A | SVS SB-1000 Pro moves more air: 12" against 9.5" is 1.6x the cone area, not the 1.26x 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 | Dynaudio Sub 3 is about 40% 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 3 years. A subwoofer amplifier works harder than anything else in the system, so this is not a throwaway line. |
| Price | A | SVS SB-1000 Pro costs less - $600 against $1,399, about 57% less. |
A SVS SB-1000 Pro B Dynaudio Sub 3
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 Dynaudio Sub 3 if one of the "depends" rows describes your room. 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 $600 each, two SVS SB-1000 Pro cost about $1,200 against $1,399 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.
