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.

This controller is heavy-duty, high quality, and easy to connect. My new controller came with improved screw terminals instead of the cheap push-down connections. Each of the 3 terminal strips can unplug from the back for even easier connection of wires, but it was easy to connect without removing. The scree terminals are industrial grade, the same as we have in control panels at work. My 16 ga wires fit easily into the terminal, as I'm sure 14 ga would also. Switches feel heavy duty. Cabinet is nice. Price is right. Excellent Value!

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.

Received this item via USPS today. (a day later than expected/promised when ordered). It replaced another similar switch which died after 2 years of use. I give this item a 10 for user friendly and ease of set up. As shown in the pictures for the item on Amazon, the terminal blocks are removable. Wires are clamped to it with small screws (again as shown in the Amazon listing). Only potential issue is the smallness of the slotted screw head. My set of jeweler screwdrivers did the trick but as the screw heads are recessed, my smallest Craftsman screwdriver would have been too big.So, switches feel solid, the terminal block seems like it will stay plugged in, easy to set up, working fine for now.

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.

I like the small size, it works well. I use it to switch between 2 amps, that run a pair of speakers. I have a 200 wpc amp when im in the mood for heavy metal. Also a have a smaller 20wpc amp for general use. With a push of a button i can use either easily.

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.
