Sony SACS9 Vs. Polk PSW10

Here is the comparison between the two subwoofers:

Amplification Type

Sony SACS9 and Polk PSW10 are front-firing subwoofers with built-in amplifiers. And that means both subwoofers have a dedicated power source to drive the subwoofer.

You will not require a separate amp/receiver to power the subwoofers.

Both subwoofers, Sony SACS9, and PSW10, are active/powered subwoofers, meaning both subs have built-in amplifiers.

The Sony SACS9 features an active subwoofer with built-in amplification, utilizing a 115W amplifier to drive its 10-inch cone woofer. On the other hand, Polk PSW10 with a power rating of 50 watts. It also utilizes a 10-inch dynamic balance composite cone driver for delivering deep and impactful bass.

Both the subwoofers have high-efficiency drivers, but the driver in the Sony SACS9 is much more power-hungry.

Design & Build Quality

The Sony SACS9 features a sleek, modern design with a black ash finish that can easily blend in with most home decor. It has a sturdy construction with a durable MDF enclosure that minimizes resonance and distortion.

On the other hand, Polk PSW10 is a stylish compact sub with a black laminate finish. The PSW10 cabinet is also very well-built and very good at minimizing distortion.

Speaking of the ports, or some call them vents, both speakers feature one. Sony SACS9 has on the rear panel and PSW10 on the front side.

Front port/opening designed to radiate bass waves directly from the front of the enclosure towards the listener. This can result in more precise and punchy bass, with a tighter and faster response. With the front port, you can also have flexibility in subwoofer placement as they are less affected by being placed close to walls or other obstacles.

Alternatively, rear ports deliver boomier and less precise bass, with a slower and less tight response.

The choice between both depends on personal preference, room acoustics, and intended use. It is very important to consider your listening environment, room acoustic, and the quality of the subwoofer to decide which will be better.

But in general front ports are recommended for tighter and more accurate bass. At the same time, rear-ported subwoofers may be suitable for larger rooms or situations where a boomy bass response is desired.


Sony SACS9 main controls are on the rear side of the subwoofer. The controls include volume control, crossover adjustment, and phase switch; no app control feature is available for the Sony SACS9 sub. 

A knob on the rear side is located to control the sound levels. In addition, a LED light is also built into the sub that appears red when the subwoofer is on standby and green when powered on.

The power button is built on the sub’s rear to switch off the sub. This subwoofer’s auto-on and off feature makes it easy to connect and operate.

Regarding Polk PSW10, the Volume control, phase switch, and low pass are built on the sub; no app control option is available for the Polk PSW10; however, the built-in controls are easy to understand, and setup is easy and hassle-free. 


Various methods can integrate the Sony SACS9 and Polk PSW10 into a home theater system.

Sony SACS9 features both line-level and speaker-level input, making it compatible with various audio systems. The line level output can connect a subwoofer and RCA or output receiver or amplifier. In contrast, the speaker level inputs connect the sub directly to the home theater system output. 

Similarly, the Polk PSW10 features both line-level and speaker-level output, making it compatible with many audio systems to produce excellent frequencies of high and mid-range. 

The speaker level input can connect this sub directly to the output of the receiver or amplifier, whereas the line level input is used to connect to the RCA output. Polk PSW10 speaker-level output is the perfect solution to low bass problems. 

Frequency Response:

The Sony Sacs9 offers a minimum frequency response of 28Hz, and the max is 200 to generate the best level sound. For maximum use of the low-level converter function in Sony SACS9, set the cut-off frequency controller at 200 Hz.

Polk PSW10 provides ideal volume and eliminates the distortion at low frequencies with heavy-duty MDF chassis, the minimum frequency response of Polk PSW10 is 40Hz, and the maximum is 160 and with a crossover of 80 to 160 Hz. 

When compared, it was noticed that the Polk PSW10 could reproduce the lower bass frequencies more accurately than the Sony SACS9.

Overall Performance

In terms of sound quality, both the SACS9 and the PSW10 are impressive.

The SACS9 produces a rich and detailed bass that adds depth and impact to your audio, making it a great choice for immersive home theater experiences. It also offers excellent clarity and accuracy, allowing you to hear every nuance of the bass notes in your music.

Similarly, the PSW10 delivers tight and punchy bass that enhances your audio listening experience. It provides a well-balanced bass response that complements the main speakers without overpowering them, making it suitable for a wide range of audio applications.

One notable difference in sound quality between the two subwoofers is the frequency response range. The SACS9 has a lower frequency response of 28 Hz, which means it is capable of reproducing lower bass tones with more authority compared to the PSW10, which has a frequency response range starting from 35 Hz.

However, the difference may not be noticeable to everyone, and it largely depends on your specific audio preferences and listening environment.
