Home Speaker Detector

Introduction: Home Speaker Detector

Hi everyone,
Today I will show you a little trick that will help you find out which speaker is which in your home theater system.
Not clear enough?
Let's say you just installed a new speaker system in your TV room, you put up all the speakers, you pulled all the wires to the back of the sound receiver... and if you're like me, you probably hid the wires in your walls.... 
But now you have a bunch of wires in the back of your sound receiver and you don't know which one goes where.
I'll show you how to find out in just a sec. Let's get on to the pictures and you'll see better:

    You could use an AA battery, the lower voltage affects the speakers less, but you must remove the grill to see the woofer movement that the AA battery causes

    Using a 9v dc battery on a speakers or crossovers could cause damage. Use a cable tracker instead.

    The 9v battery doesn't have enough amps to damage anything in a home theater speaker, but you can use a AA or AAA battery if you want.

    That might be ok for a sub and a heafty midrange. But it could very well overdrive the mechanical limits of a tweater or delicate dome mid. It's up to you if you want take that chance.

    +1... this is very dangerous to the speaker. Cheap trackers cost aprox $20. Decent speakers cost well over $100 each... do you really want to take that chance? Unplug both your amp and your speakers and use a tracker... it's really a whole lot safer if you have decent speakers. You have to realize that the voltage that it takes to drive consumer speakers is very low compared to a 9V battery. A 1.5V battery is a little safer, but that's still not what the speakers are designed to do. Maybe you should research how speakers and sound actually work... before you cause someone to actually destroy them.

    No problem. I make part of my living by A. Running professional audio for live and recorded events, and B. Installing high end home theaters (the kind where people don't have anything better to spend their money on then spending $900+ for each speaker in a 7.1 surround sound system.  (Not even including the amp!)  So if I ever tried to use this method, I would be homeless right now!  ;)

    Nice. That what I do also, high end home theaters, bars and restaurants.

    Yep, I do the home theaters and I mostly work with live theater for sound, but I've done everything from theaters to bands to bars to DJing to recording, you name it, I've probably done it. :)
