Speaker Polarity

This app accurately identified the speakers out of phase. Bluetooth connected, turned on the test tone, held my phone in front of each of the speakers.

Follower instructions, Bluetooth and wired. I tested it on car speakers, my TV and the speaker I bought from the store. Even the speaker that was intentionally crossed wired

Works great with Bluetooth, (doesn’t work when Apple Car Play is running, but does with Bluetooth) Within 2 minutes I was done. Found out 3 speakers were backwards, literally the most useful app I’ve ever downloaded.

Moved into new house with speakers built in everywhere to the ceilings and walls. No idea how the wires are connected, and i’m not about to go around removing each speaker from the wall and ceiling to see how they are attached (i tried one one, but they are very difficult to remove). I needed to know the correct polarity so that I could correctly calculate the impedance of various series and parallel circuits of speakers with the amp so i didn’t overload it (in addition to them having optimal sound). The builders of my house did not seem to follow any sort of convention or pattern when installing the speakers and connecting the wires, unfortunately. Using the app I was able to see that approximately 25% of my speakers were wired backwards and I simply matched this backwards wiring on my wall plate to ensure that I have the correct polarity everywhere. This app save me hours and hours and hours of difficult work and I will be forever grateful!!!

I ran the WAV click file from their website through my stereo (using my iPad), then held my phone in front of each speaker to check polarity. 3 out of 4 of my speakers were negative, so I reversed the wires on those. Very quick and easy.

Save your money !!!

Installed new speakers, head unit, and amplifier in my project truck. When using the factory wiring to connect to aftermarket speakers, it’s challenging to know the correct wiring schematic, even with a harness. After install I wanted to see if I did the wiring correctly... nope all speakers out of phase. This app gives a simple “-“ or “+” based on the phase of your speakers. I would have given 5 stars, but this app must of been created in an hour. It’s very poor with little to no instructions. What I did. Visit the app designers website on a Windows or OS computer and download their “Speaker Pop” audio file. From there I added the “long pop.wav” file into iTunes. I used my iPad as the music source (plugged in my iPad to the usb of my stereo), then used the app on my iPhone to read the sound from the speakers. The app used the microphone on your iPhone to read the signal. The microphone is located where the charger is (bottom of iPhone). Make the wire swap at the speaker, behind the head unit, or amp (my case, the amp under my seat) then test again. The test is only good for mid-speakers (door speakers), not tweeters (locates usually in the A-pillar or dash).

Just built a new audio system in my car and I was struggling with some weird polarity issues coming from the OEM head unit. I downloaded and burned the WAV file to CD and played it on repeat. And then one by one I could test each speaker simply by hold my phone near it. Brilliant!

I recently hooked up surround speakers in a house that was pre wired for them. Unfortunately whoever wired it chose to use plain wire without any indication of positive or negative. I was strongly suspicious that my speakers were wired backward, and I found this app. Sure enough one of the surrounds was out of phase, and after fixing it they sound dramatically better! This is one of those apps that is well worth the 5 bucks. I'm very pleased. Thanks!

I installed an amp and upgraded speakers on my motorcycle. Took great effort to install everything according to my wiring diagrams. After it was all done my front speakers just didn't sound right. Same speakers as the rear but nowhere near the quality as the rear speakers. I took the bike apart to check my work. I did it right but using a multimeter I discovered that the original bike wiring was wrong. POS and NEG wires were backwards even though color coding and connectors were correct. Strange I know. I fixed it but something was nagging me about it. Was the factory wiring really wrong? Could it really be? Researching and double checking my thought process on what I discovered and "repaired", I came across this app. How simple could it be. 5 minutes after purchasing I verified that now my speakers are indeed wired correctly. All I can say is THANK YOU! I only wish I could have had this before I redid the wiring to show me it was audibly wrong at the time. Better late than never and the piece of mind is well worth the price of the app!!!
