In this review, we will be comparing BalancedForce 210 and PB-1000, two Powered Subwoofer speakers from MartinLogan 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 MartinLogan BalancedForce 210 and SVS PB-1000 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.MartinLogan BalancedForce 210 and SVS PB-1000 have a totally different setup: the MartinLogan BalancedForce 210 features 2 x 10-inch drivers whereas the PB-1000 features 1 x 10-inch drivers.
Frequency Response
BalancedForce 210 has a frequency range of 20-120 Hz whereas PB-1000 has a frequency range of 19-270 Hz. With a minimum frequency of 19Hz, the PB-1000 can go slightly deeper then the BalancedForce 210'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 MartinLogan BalancedForce 210 has a Acoustic Suspension type cabinet. 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. On the other hand the SVS PB-1000 have Bass Reflex type enclosure. Bass Reflex type subwoofers (aka Ported, Vented or Reflex Port) have enclosures that uses a port, hole or vent cut into the cabinet. Ported designs are generally more efficient than the Sealed 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 MartinLogan BalancedForce 210's and SVS PB-1000's external dimensions. MartinLogan BalancedForce 210 has external dimensions of 485.0 x 486.0 x 543.0mm (19-1/16inch x 19-1/8inch x 21-3/8inch) whereas SVS PB-1000 has external dimensions of 480.0 x 381.0 x 532.0mm (18-7/8 x 15 x 20-15/16inch).
MartinLogan BalancedForce 210 is clearly the larger of the two speakers. Its body is 105mm wider, 5mm taller and 11mm deeper than SVS PB-1000.
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 MartinLogan BalancedForce 210 is approximately 2639.0cm2 / 409.0inch2 and base area of the SVS PB-1000 is approximately 2026.9cm2 / 314.2inch2. The BalancedForce 210 requires 30% more surface area than the PB-1000 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 MartinLogan BalancedForce 210 weighs 43.64kg / 96lbs and the SVS PB-1000 weighs 20.91kg / 46lbs. This makes the BalancedForce 210 109% heavier than the PB-1000.
Here is a comparison of how BalancedForce 210 and PB-1000'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.
MartinLogan BalancedForce 210 needs about 30% more floor area.

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 | evenly matched | Effectively the same reach (20Hz vs 19Hz). |
| Amplifier power | A | MartinLogan BalancedForce 210 has the bigger amplifier - 850W against 300W RMS, about 4.5dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | A | MartinLogan BalancedForce 210 moves more air: 2 x 10" against 10" is 2x the cone area, not the 1.41x the diameters suggest. More area means the same output with less excursion, and less distortion with it. |
| Enclosure | depends | MartinLogan BalancedForce 210 is sealed - a sealed box rolls off gently and is usually the easier one to integrate in a small or awkward room; SVS PB-1000 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. |
| Driver placement | depends | MartinLogan BalancedForce 210 fires side and SVS PB-1000 fires front. A down-firing driver is more forgiving of a grille-less look and of a hard floor; a front-firing one is the safer choice on a thick carpet or a suspended timber floor. |
| Cabinet size | depends | SVS PB-1000 is about 24% 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 PB-1000 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 PB-1000 costs less - $499 against $3,499, about 86% less. |
A MartinLogan BalancedForce 210 B SVS PB-1000
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?
MartinLogan BalancedForce 210 is ahead, but on only 1 of the measured areas, and it costs about 7x the price. SVS PB-1000 is the sensible buy unless your room is large enough to need the extra. Films or music? If this is mainly a home cinema, SVS PB-1000 will hit harder for the money; if it is mainly for music in a normal-sized room, MartinLogan BalancedForce 210 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 $499 each, two SVS PB-1000 cost about $998 against $3,499 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.
