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

Needed to split speakers so I could hear the set outside in the driveway, or the set inside the garage, or both at the same time. This worked perfectly. Tested quality without the switch and with the switch, no loss of quality at all and no loss of sound. Sized the speaker cables according to online tools. This device is high quality and I'll never worry about the cables coming loose with the way it ties them down. Really good product.

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.

Works well. Like the wiring modules

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.

Modern technology is not all it cracked up to be but there’s always one more piece of tech that will solve your problem. This was it. This product allows us to switch different outdoor speakers on and off through our receiver which is set up for home surround sound. It’s small, easy to tuck away and does the job that no customer support person could figure out. I highly recommend it if you are dealing with a newer receiver and are trying to some or all speakers at any specific time.

I used the Tenealay a/b switch to switch a 40 watt guitar amp external speaker 1/4 in output jack to run the signal through a 1/4 male plug to 14 ga wire cable to the left (very nice JBL) speaker of my stereo hi-fi system, to use it as a much better monitor speaker -during guitar play- than the guitar amp's speaker. I can switch back to the stereo for music listening without yanking wires or cables. I would prefer the more standard speaker wire spring clip wire posts you find on the back of good speakers and audio equipment, but the screw-down connectors work okay too. I used 14 ga speaker wire with some fitment issues; good luck with 12 ga wire. I have no issues with impedance or sound quality. For me, it was a reasonably-priced solution and worked exsctly as I envisioned.

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...

Average quality but works and sounds good. The removable plugs on the back are convenient for hook up.
