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.

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

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.

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.

Great for what I needed. Simple switch A/B; nothing more, nothing less. Will not accept 14ga wire; well, it could if you want to spend a lot of time fuzzing with it or tinning the wire ends. 16ga or smaller works great. The connections work well and are strong if you know what your are doing. Loosen the connections screws all the way (use a small screwdriver); strip just enough of the wire (3/8 to 5/16") and insert all the way into the slot, then tighten screw just enough to secure the wire, don't over tighten. Personally, I would not use both speakers at once unless you are damm sure your amp can handle the combined impedance since the terminals are wired in parallel. I use mainly to compare speakers since my amp is a small desktop Duok Audio ST-01-Pro.

I disliked the fact that it didnt work after two hours of trouble shooting. It took two hours because of the micro screws. There are 4 speakers involved. It was a mess.I put the same wires directly into my receiver and it works. I switch the right and left on this piece of junk and it works. Right worked left didnt.Dont buy.

It works. The construction quality is very cheap. The binding posts, if you can call them that, are weak and too close together. It seems to pass audio without any loss of sound quality. I just feel that I've overpaid for this really cheap piece of plastic and I worry if it will last past my return window, but I'm keeping it for now.

I was looking for something to switch the speakers between our living room and the patio. This has saved me from buying another amp/receiver for the patio. Easy to use.Could have had light to show which side is ON.
