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.

Excellent value and understated aesthetic. I'm using it in conjunction with a La Voix du Luthier Onde for live music performance on guitar, banjo, accordion, synths and more. It provides more than sufficient volume for my application.

This unit is compact and provides a clear low bass. better utilized in smaller rooms (vs let's say a living room size). I set this up in my game room and it worked for a while. Then the unit started shutting off or auto switched over to stand by. i would have to turn off then on again for the bass to kick in. Of course was very annoying to correct every time this incident occurred. I'm glad to say that im still a satisfied customer as (after a few back n forths) their customer service has offered a resolution. I really liked this unit and how compact it is and was bummed when it started glitching but their service really stepped in and provided the support needed.

Tried to connect this to my Yamaha receiver and no audible sound would come out, not even a vibration on the speaker. I decided to hook my Polk subwoofer to the receiver and it produced the bass just fine. I hook this box to my Denon where my Polk came from. The box showed signs of some sound. No matter how loud I tried to turn the volume up, the bass barely came out. There is no indication of max volume either! Hooking my Polk back to the Denon, the Polk worked just fine! Final decision, returned to Amazon! I get what I paid for.

I tend to over analyze my purchases, even something as trivial as a $75 sub-woofer. I have a pair of original M-Audio Av-40 bookshelf speakers. They sound incredible for gaming, music, and zoom calls. I was really beginning to miss the bass though. I spent a long time research different setups and woofers to go with my personal setup. I had been running a USB Hub to (USB to RCA Converter) into my Av-40s so I could easily utilize for both my home gaming PC, as well as my Macbook Pro for work. I saw a lot of negative reviews about the sound, and hard to setup, etc. It is no exaggeration to say I swapped the input to the AV-40 for the sub RCA inputs, then used another RCA cable to connect the output of this sub to the AV-40 inputs. Worked perfect immediately. In terms of sound quality, I am no audiophile. I have a very small basement office (8x7). This tiny 6.5 inch sub, even on low to medium gain, and without tweaking my filter for the bookshelf speakers.. HITS HARD AS ALL HELL. Its extremely punchy, compliments the clarity of my mid and high from the AV-40. I smile every time a punchy bassline comes on spotify and wonder why I did not buy something like this sooner. No comment on the bluetooth or other features, but RCA inputs and outputs is working flawlessly for me. 5 out of 5, would recommend for anyone that wants to add a woofer to their bookshelf setup.

Pictures show a diff rca cable than what came .. it’s just one ..so from sound bar bass out to lfe on back of bass…. And now you can use the remote to adjust it … I set the knob at back to 3/4 and this thing is great ….. brought new life to movies music and the like

Lo tengo con mi equipo de sonido Technics (de hace algunas décadas) y funciona muy bien, parece que los bajos salieran de las bocinas normales, lo recomiendo ampliamente.

Tuve una mala experiencia con este equipo, está muy lejos de cumplir lo que promete, ya que se escucha muy mal, lo conecté a amplificadores, de diferentes marcas, cómo Fosi, Yamaha, también lo comparé con otro subwoofer y el resultado es que se escucha muy mal

Pero fin encontré un sub con entrada optica! El bass es fuerte y aceptable considerando su tamaño. El foco rojo del stand by nunca apareció así que hay que apagar, desconectar, el Woofer de la corriente cuando no se usa. No me arrepiento de haber comprado este equipo!

Es demasiado caro, para el tamaño. No es la gran cosa. Solo sirve para escuchar unos bajos pero no tan fuertes, si se le sube todo el volumen, distorsiona. Pero si funciona, para algo decente. Nada comparado a un equipo, semiprofesional. Me gustó, solo para usar en pequeños espacios.

A pesar de que especificaba que tenia opción bluetooh y óptico, el equipo no contaba con ellas.
