In this review, we will be comparing PB-1000 and CW8, two Powered Subwoofer speakers from SVS and Monitor Audio. 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 PB-1000 and Monitor Audio CW8 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 PB-1000and Monitor Audio CW8 have a single woofer setup however the SVS PB-1000's woofer is 10-inch whereas the Monitor Audio CW8 features a 8-inch woofer.
Frequency Response
PB-1000 has a frequency range of 19-270 Hz whereas CW8 has a frequency range of 35-135 Hz. With a minimum frequency of 19Hz, the PB-1000 can go significantly deeper on the low side and provide stronger bass compared to the CW8'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
The SVS PB-1000 has a Bass Reflex type cabinet. 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. On the other hand the Monitor Audio CW8 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 SVS PB-1000's and Monitor Audio CW8's external dimensions. SVS PB-1000 has external dimensions of 480.0 x 381.0 x 532.0mm (18-7/8 x 15 x 20-15/16inch) whereas Monitor Audio CW8 has external dimensions of 274.0 x 262.0 x 326.0mm (10-3/4 x 10-5/16 x 12-13/16inch).
SVS PB-1000 is clearly the larger of the two speakers. Its body is 119mm wider, 206mm taller and 206mm deeper than Monitor Audio CW8.
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 PB-1000 is approximately 2026.9cm2 / 314.2inch2 and base area of the Monitor Audio CW8 is approximately 854.1cm2 / 132.4inch2. The PB-1000 requires 137% more surface area than the CW8 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 PB-1000 weighs 20.91kg / 46lbs and the Monitor Audio CW8 weighs 9.55kg / 21lbs. This makes the PB-1000 119% heavier than the CW8.
Here is a comparison of how PB-1000 and CW8'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 PB-1000 needs about 137% more floor area. SVS PB-1000 stands 206mm further into the room. SVS PB-1000 is 206mm taller.

A ported subwoofer against a sealed 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 | A | SVS PB-1000 goes deeper - 19Hz against 35Hz. Under 20Hz is felt more than heard - the bottom of a pipe organ and the bottom of a film mix. |
| Amplifier power | evenly matched | Much the same amplifier (300W vs 350W RMS) - under 1dB apart. |
| Driver area | A | SVS PB-1000 moves more air: 10" against 8" is 1.56x the cone area, not the 1.25x the diameters suggest. More area means the same output with less excursion, and less distortion with it. |
| Enclosure | depends | 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; Monitor Audio CW8 is sealed - a sealed box rolls off gently and is usually the easier one to integrate in a small or awkward room. Neither is better in the abstract; ported tends to suit films and sealed tends to suit music, and both generalisations have exceptions. |
| Speaker-level inputs | A | SVS PB-1000 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. |
| Cabinet size | depends | Monitor Audio CW8 is about 76% 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 | Monitor Audio CW8 costs less - $450 against $499, about 10% less. |

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 PB-1000 leads across most of the measured areas for a modest premium, so it is the easier pick if the budget stretches. Monitor Audio CW8 is the one to take if it does not. 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, Monitor Audio CW8 is usually the easier one to make sound right. Check your amplifier first: if it has no subwoofer or preamp output, SVS PB-1000 is the only one of these two you can connect at all.
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.
