In this review, we will be comparing Studio 650P and PB-1000, two Powered Subwoofer speakers from JBL 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 JBL Studio 650P 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.JBL Studio 650Pand SVS PB-1000 have the same driver set up: Both subwoofers have 1 x 10" drivers.
Frequency Response
Studio 650P has a frequency range of 35-150 Hz whereas PB-1000 has a frequency range of 19-270 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 Studio 650P'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.

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 JBL Studio 650P's and SVS PB-1000's external dimensions. JBL Studio 650P has external dimensions of 444.5 x 395.3 x 458.8mm () 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).
JBL Studio 650P is 35.5mm shorter and 73.2mm less deeper than SVS PB-1000 but it is also 14.3mm wider.
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.
SVS PB-1000 needs about 12% more floor or shelf area. SVS PB-1000 is 73mm deeper, so it stands that much further out from the wall. SVS PB-1000 is 36mm 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 JBL Studio 650P is approximately 1813.6cm2 / 281.1inch2 and base area of the SVS PB-1000 is approximately 2026.9cm2 / 314.2inch2. The Studio 650P requires 11% less surface area than the PB-1000 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 JBL Studio 650P weighs 10.43kg / 22.9lbs and the SVS PB-1000 weighs 20.91kg / 46lbs. This makes the PB-1000 100% heavier than the Studio 650P.
Here is a comparison of how Studio 650P and PB-1000's weights compare with the average, max and min weights in Powered Subwoofer class.

No single best subwoofer here. Your room, where the box can physically go, and whether this is mainly for films or mainly for music will settle it long before the specs do.
| Area | Better | Why |
|---|
| Bass depth | B | 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 (250W vs 300W RMS) - under 1dB apart. |
| Driver area | evenly matched | Near-identical radiating area (10" against 10"). |
| Enclosure | evenly matched | Both are ported designs, so they roll off in much the same way. |
| Cabinet size | depends | JBL Studio 650P is about 17% 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 | A | JBL Studio 650P costs less - $400 against $499, about 20% less. |
A JBL Studio 650P 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?
The usual trade-off: SVS PB-1000 measures better, JBL Studio 650P costs about 20% less. In a normal room, placement will make a bigger difference than the gap between these two.
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.
