In this review, we will be comparing SA-CS9 and S 810 SUB, two Powered Subwoofer speakers from Sony and Jamo. 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 Sony SA-CS9 and Jamo S 810 SUB 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.Sony SA-CS9and Jamo S 810 SUB have the same driver set up: Both subwoofers have 1 x 10" drivers.
Frequency Response
SA-CS9 has a frequency range of 28-200 Hz whereas S 810 SUB has a frequency range of 36-180 Hz. With a minimum frequency of 28Hz, the SA-CS9 can go significantly deeper on the low side and provide stronger bass compared to the S 810 SUB's min frequency of 36Hz.
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 Sony SA-CS9 and Jamo S 810 SUB have Bass Reflex type cabinets. 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 Sony SA-CS9's and Jamo S 810 SUB's external dimensions. Sony SA-CS9 has external dimensions of 345.0 x 295.0 x 400.0mm (11.6 x 13.6 x 15.7 inch) whereas Jamo S 810 SUB has external dimensions of 508.0 x 228.0 x 405.0mm (20 x 8-15/16 x 15-15/16inch).
Sony SA-CS9 is 163mm shorter and 5mm less deeper than Jamo S 810 SUB but it is also 67mm wider.

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 Sony SA-CS9 is approximately 1180.0cm2 / 182.9inch2 and base area of the Jamo S 810 SUB is approximately 923.4cm2 / 143.1inch2. The SA-CS9 requires 28% more surface area than the S 810 SUB 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 Sony SA-CS9 weighs 11.50kg / 25.3lbs and the Jamo S 810 SUB weighs 11.82kg / 26lbs. This makes the S 810 SUB 3% heavier than the SA-CS9.
Here is a comparison of how SA-CS9 and S 810 SUB'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.
Sony SA-CS9 needs about 28% more floor area. Jamo S 810 SUB is 163mm taller.

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 | A | Sony SA-CS9 goes deeper - 28Hz against 36Hz. A real difference, though most music has little content below 36Hz. |
| Amplifier power | A | Sony SA-CS9 has the bigger amplifier - 115W against 75W RMS, about 1.9dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| 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. |
| Driver placement | depends | Sony SA-CS9 fires front and Jamo S 810 SUB fires side. 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. |
| Price | B | Jamo S 810 SUB costs less - $199 against $248, about 20% less. |
A Sony SA-CS9 B Jamo S 810 SUB
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: Sony SA-CS9 measures better, Jamo S 810 SUB 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.
