2-Way Audio Stereo Speaker selector Switcher Box, Combiner Multi Zone A B Speaker Switch Distribution Controller Box - P21

The 2-Way Audio Stereo Speaker Selector does exactly what it’s supposed to do. I use it in my garage to switch between speakers inside the garage and speakers out in the yard, and it works flawlessly. There’s no noticeable loss in volume or sound quality, which was my main concern going in. Installation was simple and straightforward, and once it’s set up, there’s really nothing to think about. Flip the switch and it just works. No noise, no signal issues, no complications. If you need a basic, reliable way to switch between two sets of speakers, this is a solid, no-nonsense solution.

I used this to add sound out at my fire pit area from my garage stereo. Works very well and easy to install. I can have music in the shop or at the fire pit or both at once. Perfect!

Works great for smaller gauge wire.

This item was just what i needed in my shop to add speakers to the patio. I now can control if the music it outside/inside or both! It was simple to connect and the connectors are awesome. This product is made of Plastic with circuit board inside with great quality in construction. It will hold up over time. It is really compact in size and will fit in just about any cabinet or shelve. it does not have mounting points for racks or walls.

Somehow this makes my Marantz Imperial 7 speakers sound better. I thought I was crazy but I removed it and they sounded worse. It's well made and maybe adds a tiny bit of resistance? I have no clue, but my speakers cause a bit of fatigue and aren't as smooth unless I use this speaker selector. I have removed it and added it back and get the same result. I can't recommend it enough, it definitely doesn't degrade the signal. I took it apart to check the build quality and it is great.

I should have known better when I saw the wire connections. If you look closely, the wires are attached by a very small screw, so you have to use a very small screw driver. As I place the wires into the receptacle, which is difficult, I had to continuously hold them in place with my fingers so they wouldn't fall off, very loose. I had to retighten the wires and the connections fell apart. I guess you get what you pay for...

I bought one before that couldn't handle the wattage I was putting out. It would shut off. This unit has worked and I'm using a 140 watt per channel receiver threw a 200 watt per channel amp. I would guess the volume was maybe pushing 40 watts/channel volume output, and it kept working when I switched them from A to B. Worked switching the other way as well. Only drawback I have is the wires in the back have the unit leaning back with the front up in the air. Other wise, no complaints. Can't use banan plugs is another drawback, but the wires work fine. I've had this unit since May of 2023 and it's still working.Just don't go cheap because you will definetly know it when you receive it. I have not tried all 4 speakers at the same time though. not sure why you would, I bought it to compair speakers.

These work perfectly for me to transfer sound back and forth between two pairs of bookshelf speakers, depending on the type of music I am playing. Great price as compared to other speaker switch boxes.
