Review on BESTISAN Compact Bluetooth 5.0 Home Audio Subwoofer with Powerful Deep Bass Response for Home Theater Systems, TV, Speakers – Optical/Bluetooth/RCA Compatible, Black by Luxme Johnson

I bought 2 of these because SOME reviews said the bass wasn't great and because I also have an AVR (receiver) that has 5.2 channels and supports 2 subwoofers. The reason I chose them is because 1) they are active, not passive (i.e. they have a built in amplifier) and 2) they fit on a small shelf I have that would not fit in any other active subwoofer . I connected it. to my Denon S650H AVR 5.2 channel receiver (receiver) and they work great. Tips for connecting to an AVR with RCA subwoofer preouts. Obtain an RCA Y-cable (an RCA cable that splits from 1 connection to your receiver to 2 connections going to the red and white inputs on your subwoofer), connect the two ends of the RCA (white and red) with the audio of the subwoofer. In ports. The manual tells you how to connect the RCA cables from the soundbar/speakers to the subwoofer audio outputs - ignore this for a receiver, this guide is for if you don't have a receiver and want to connect your TV through this subwoofer to your speakers /sound bar. Make sure the indicator on the subwoofer is yellow (or as it's called "orange" - it's clearly not, it's yellow, maybe even bordering on green), make sure the frequency is set to minimum . As you'll notice, the volume makes the light blink when you turn it. Turn it all the way until the light stops flashing (minimum), then count up 25 turns and leave it there to calibrate your receiver - you can increase it later if you like. Some people will point out that you don't. I don't need an RCA connector (Y-cable) and only need 1 RCA cable because the subwoofer sound is mono, but I tested it with a Y-cable and it works and if I had a cable I don't know whether it's worth connecting to the red or white subwoofer input, but you can test and report, all I know is that the Y-cable works. The bass sounds very good, although it's quiet and more "local" (I hear the base coming from the sub instead of surrounding me like I've heard some other subs), but you can always turn it up, if you want more bass too People who say bass sounds bad are acoustic fans who want something premium. or people who have to shake their house when there's explosions on TV - normal people will think it sounds good, it definitely does for me. Another note: they aren't magnetically shielded, so keep them far enough away from the TV to avoid distortion. As others have noted, there is a standby mode, but it doesn't activate itself. You have to hold down the volume knob for it to go to sleep, and the knob is on the back (not easy to reach, depending on the case). where the subwoofer is located), but it shouldn't draw too much power if no sound is coming through. The frequency knob has a limit so you know how far to turn it. The volume knob spins freely, so it's hard to tell what volume it's set to, but if you REALLY care, you can turn it all the way to the left until the indicator stops flashing (minimum), and manually adjust it along with it rotate right mouse button, it will blink the light and count each one until the light stops blinking and you know you've reached the max. Now you know how many turns there are between the minimum and the maximum, and you know where the middle of the path is when you count the clicks per turn. The main advantage of this active subwoofer over others is the price and size - it was the only one that fit on my shelf. . I'm sure you can find nicer ones for twice the price, but they will be bulkier and more expensive. They are great for the price and size.
