Takeaway: Capable of producing adequate bass tones to fill in mains gap, however, lacks significant power and ultra low end support for a truly immersive physical and auditory experience.

The subwoofer comes with a 5 ft long RCA to 3.5mm jack audio cable, wall power adapter with 5 ft cord, and a quick start manual. The housing measures 9.25” square and 13” H. The body is made from a plastic coated MDF and weighs about 9 lbs. The subwoofer has a 2.5” reflex port in the back and the 60 Watt 6.5” driver for the sub is located on the bottom as it is down-firing and has a frequency response range of 40 Hz to 250 Hz. The four feet keep the sub 1” off the ground, so the sound can spread and have rubber feet for decoupling and stabilization.

On the back you have the controls. There’s a power button , LED status indicator, Aux out port, RCA line in with the left input as the low-frequency effects or LFE channel, volume dial, low pass crossover adjustment dial from 60 – 250Hz, 0 or 180 degree phase switch, and DC in power port. For me, since I’ll be putting the subwoofer on the same side of the room as my mains, I’ll keep the phase setting on 0 and as my receiver will be handling the crossover, I’ll dial the low pass cutoff frequency to the highest setting.

In a frequency test for the sub I found that although the device is only rated as low as 40 Hz, at 20 and 30 Hz, I did hear a little bit of sound being produced from the woofer, but it didn’t start to sound significant until we hit 40 Hz. As the frequency went higher there was a bit more volume produced, though it started to plateau and drop off after 120 Hz; if you’re looking for a cutoff value for this sub, depending on how low your mains can go, I’d target somewhere between 80 and 110 Hz.

When listening to a sub-boosted sound sample with and without the Bestisan sub turned on, the was a clear difference with the sub active in that the lower registers were more fully supported, and the bass tones and beat had more kick and weight to them. That’s to say the Bestisan sub does successfully add bass to the mix, which was somewhat lacking, even on my Hi-Fi Martin Logan bookshelf speakers; however, due to the limited size and power of the Bestisan sub and small amount of bass range extension over the speaker’s native lows of 56 Hz, it wasn't particularly a game-changing experience. I think the sub does a nice job at simply rounding out the sound and made my listening experience a little fuller and richer, but it didn't wow me with an impressive rumble.

Overall, if you’re looking for an inexpensive way to add some bass to a system that’s lacking in this area, the SW65C is an okay choice for those on a budget or with a small space that the amount of sound it outputs can fill. But if your space is large or you are willing to spend a little more, I’d shoot for a more solid 100Watt option like the Polk PSW10 which can deliver more immersive, body rumbling lows.
