What We Don't Like

Sony makes just about everything, and their addition to sub-$200 monitors is no exception. The SACS9 is a full featured subwoofer that pumps out thunderous bass. Sony shows why their name is so prominent in, well, every field.


The design here is a little barren. Upon first glance, the subwoofer appears like just a black box, with a removable front grille that has a beveled edge on the top. Removing the grille reveals a navy blue speaker cone much in tune with the rest of Sony’s speakers. On the back, there’s inputs and outputs, RCA input, phase and power saving switches, a rear port, and volume and low-pass frequency.

For me, the look of the subwoofer with the grille removed is a winner. The design is a little boring, and adding an additionally boring grille to the front makes the SACS9 scream low-quality which is a shame because it certainly is not. However, taking off the grille reveals the gorgeous navy speaker and makes this subwoofer look as good as it sounds. It should be noted that there are Sony logos on both the grille and the inside of the cabinet, so you’re not going to be able to avoid that.


Thankfully, the Sony SACS9 is much more feature rich than other speakers in this price bracket. The subwoofer holds a tunable crossover, ranging from 50 Hz – 200 Hz to tighten up the low-end if needed, an automatic power saving mode that puts the subwoofer into standby when it doesn’t sense audio, as well a phase switch to make sure the sub is firing in phase with the rest of your speakers.

Overall, I can’t complain about the feature set here for the price. A tunable crossover provides a nice range that really helps reign in low-end, and a phase switch means that you can really get the most out of the subwoofer. While some additional tweaking options are always nice to see, the lack of them wasn’t missed much here. That’s largely due to the fact that the subwoofer sounds fantastic on it’s own, so minimal tweaking was necessary.


The star of the show really is in the performance, though. The SACS9 sounds incredible, producing thunderous low-end with each hit in the subs. The 10-inch foamed-mica cellular reinforced woofer is tight, dynamic, and responsive, reproducing low-end with ease all the way down to the rated 28 Hz.

Sony clearly shows their expertise in the field of audio with this subwoofer. Listening to music was as enjoyable as ever, and watching movies in a home theater set-up reproducing explosions, gunfire, and more with ease.
Overall, this subwoofer is punches like few others, giving a tight and responsive low-end that doesn’t become obnoxious in context of other speakers.

The Rumble:

The Sony SACS9 is a fantastic subwoofer at the price. Sony’s expertly designed 10-inch foamed-mica cellular reinforced woofer is tight and dynamic, producing monstrous sound while still blending in with almost any system.
