Powered Subwoofer, Bestisan 6.5" Active Home Audio Subwoofer in Compact Design for Receiver,Deep Bass in Black

Back in 2017, I wrote a review for a pair of Edifier R1280T bookshelf speakers that I had bought for myself. I loved them and still do. I've since gotten another pair, in fact. When I wrote that review, it was an honest, unsolicited review of a product I thought deserved praise, not a review written with any sort of motive. I'm not a professional reviewer or "influencer" or anything like that. Little did I know, that review racked up tens of thousands of views and hundreds of "This was Helpful" clicks. Cool. Glad to have been of help! A few days ago, I got a message from Emma, a rep for an audio manufacturer called Bestisan, who had seen my review and wanted me to take a look at a subwoofer of theirs, one designed to pair well with powered speakers like the Edifiers. I agreed to purchase their subwoofer with my own money, so it would be the "verified purchase" review you see here. Why would I do this? Well, I figured that if I really didn't like it, or I found some fault with it, I'd return it to Amazon, leaving me to write what I honestly think, with a clear conscience and very little risk. (Edit: Just to clarify, I am not accepting any compensation for this review!) The subwoofer arrived a few days later and a couple of days after that, I got around to unboxing it and setting it up. It was well packed. Inside the cardboard shipping box were a couple of styrofoam supports and the sub wrapped in plastic. Not fancy, but sensible and utilitarian packaging. A plastic bag held the manual, a 3.5mm to RCA analog cable, as well as an optical cable. (Hmmm. Optical. Cool.) I set the instructions aside as Emma had mentioned that some people had trouble setting it up correctly and I wanted to see what I'd run into. The unit itself was solid and felt like modern, quality construction. It seems to be heavy gauge ABS, rather than the vinyl-covered chipboard that these things used to be always made of. The sub has just enough texture to not look or feel cheap. With a sub, though, looks really don't matter as it's going to likely spend its days out of sight. On to setting it up! The last time I used a subwoofer, it was designed to be attached to the amplifier, from which it received the signal. Not so, the Bestisan. This is designed to be the first thing in line. The signal source goes to the subwoofer first. From there, a line-level output goes to your soundbar, amp, or powered speakers. I found this conceptually confusing at first, but soon it made perfect sense. Being first in line to receive the signal, they had the good sense to throw in a couple of extra input options. (Bluetooth? Sure! Optical? Why not?) Bluetooth is great if you want to wirelessly connect your phone. This was something my speakers didn't offer. (It was an option I opted out of.) The digital optical input is also cool to have. Your TV probably has an optical out, so you can use that to get the best possible signal, while still using your analog gear. Setting it up, I connected the RCA cable from an Amazon Echo Dot to the input and then from the output to my Edifier speakers. Something wasn't right. I was getting only intermittent sound from the sub and nothing from the speakers. This must be what others had run into. I checked the connections and gave it another try. At this point, I noticed that pushing one of the knobs changed the color of the LED. A couple of taps and it was flashing blue, which told me that it was in Bluetooth connect mode. I checked my phone and sure enough, the Bestisan was in the list of available devices. Cool. A moment later, it was connected and it sounded fantastic! Rich sound streamed from the sub and speakers. I tapped the input selector a couple more times and the signal from the Echo Dot was streaming in full, glorious quality (I think it was probably set to Optical when I first plugged it in.) I spent a few minutes playing with the levels. What I found was that if you set the subwoofer's volume and Low Pass each to about 50% and adjust your input volume, you can quickly find a good setting. Add a bit of bass, dial it back, crank it up, play with it. When it sounds about right, you'll find that the sub's output is well-paired with the volume of the speakers at every volume, no adjustments needed. So, do I recommend this? Yes, I do. Whole-heartedly, in fact. The Bestisan subwoofer adds just enough richness to the sound of the Edifiers. Digital music sounds much, much better. The speakers sound bigger and the sound fills more of the house, while never sounding harsh or booming. I didn't think I needed a subwoofer with these speakers, but now you'd have a hard time taking it away from me. So, Emma, thanks for your patience in waiting for my review, but more than that, thank you for introducing me to the the Bestisan SW65D powered subwoofer! I'll be soon ordering another, to go with my other pair of Edifiers. Also, tell your bosses to give you a raise.

This is an excellent option if you want good subtle bass that mixes in nicely with other speakers. I use it with bookshelf speakers, and it picks up exactly where those leave off. However, I've noticed there are plenty of high watt subs that rattle your fillings loose with even a small amount of volume. I think this one blends into the soundstage nicely without becoming a smack in the face of sub bass. Plus it's not hideously expensive at all.

4 stars because specs missing Optical and Bluetooth, sound like there is 2 models but same SW65D Subwoofer, my came with lfe, aux, RCA, and stereo hooks for speakers in and out. I like the sound at 70hz and minimal volumen 0 fase. I will update after couples days so far is good Punch. But Bestisan have to make his mind about sale specific SWD65 one with LFE and another with Bluetooth and optical. Which one is the new model?

Sounds ok but I have to reboot it constantly, very frustrating

Does a great job. All I need.

I can't believe the low tones out of this small subwoofer. It actually shakes the glass windows at low to medium volume. Subwoofer is connected to a hybrid tube amp with 100 watts of power. It only takes about five watts of power for this unit to get the walls and window shaking

I connected my TV to it using 3.5mm to RCA cables. Optical would have been nice but then you cannot control the volume with the TV remove (in most TVs the optical output is fixed volume), and I don't want to reach out to the back of the subwoofer to control the volume all the time. I found out that the unit never goes to standby on its own. It stays in the mode I'm using (amber for analog input) forever. Power consumption is not a lot while there's no input, though (around 2.6W). Another inconvenience is that I didn't find any way to know what volume level the unit is at. The rotary encoder spins forever and there's no other visual indication to tell you that you've reached max (or min) volume. A useful feature of this unit is that it has a line-level output, that I use to pass through to an amplifier to drive bookshelf speakers. That works well. I find that the bass output is not what I was expecting, even considering the size. I'm using it in my bedroom which is admittedly more or less large, and even though music sounds better now with added bass, in movies you can barely tell the difference. Overall this subwoofer adds some bass to a system without taking a lot of space. For about twice the money you can get something like a 10" Polk Audio that will have a lot more bass output and have auto-standby, but occupying a lot more space. Another alternative option would be to get a soundbar with a subwoofer, which is the one I'd recommend if you don't already have a speaker setup that you want to keep, like I did.

I was looking for a budget/compact subwoofer for my office. I wasn't looking for anything crazy as far as power; just something to give a little more low punch to my satellite speakers. I figured I'd give this brand a shot. Unboxing, I immediately noticed how light the speaker is. Having dealt with home/car audio for the past 20years it kind of threw me off, but I had to remind myself that the goal was not to raddle windows or floors. Rest of the setup was a breeze and my Yamaha receiver had no issues doing the mic calibration. Day 1: I was satisfied with the purchase. I did notice that even in the corner of the room, the sub sounded very "directional". IE the lows were coming from THAT corner, not the subtle non-directional lows that subs typically complement the rest of the system. Once again, it was something I was willing to accept based on what I was looking for. Day 2: I noticed while actively looking to music, I didn't hear any lows. I checked the sub and saw the blue light was on and checked the knobs to verify that they were mid-range (I use my receiver for the configuration). I then power cycled the switch and it started working again. 10mins later, it did it again, then again...and again...You get the point. I read that some folks were having issues with the auto-shutoff feature so I decided to make sure that it wasn't my cable. I volt tested it and even swapped the cable with a spare to verify it wasn't a cable issue. I'm of the opinion the auto-on/off feature has malfunctioned. Unfortunately this model does not allow you to turn the auto function off. 2 Stars overall. Sounds okay when it works, mostly likely below average electronics supporting the subwoofer. Will be returning.
