Hi guys,

I have a TEAC DRH300 with some Mission M32i speakers.

I believe both components are mediu-high range.

Anyways as I was wiring the speakers back the other day - I accidentally wired the (+) to (-) and the stereo worked fine but only a bit quieter and has a 3D (?) higher treble sound to the sound generated.

As far as I know, wiring the (+) and (-) together will damage the AMP + Speakers and the circuit will not work at alll; luckily, both components worked fine afterwards.

Anyway does anyone know why it would produce an almost 3D ; higher treble sound?

Is it to do with Parallel/Series wiring?



Thanks

Reversing the + and - will result in the sound being out of phase. It will still work and won't necessarily cause damage to the speaker and/or amp but has the potential to do so if driven at high volumes.

As sbiddle said you wired the speakers out of phase.
The effect this has is that each speaker cancels out the sound coming from the other speaker and results in less bass.
This is basically how those noise cancelling headphones work.
They have a microphone on the outside that picks up any constant noise around you and plays the same thing back out of phase inside your ear (with some processing going on as well) which cancels out the noise so you don't hear it (or most of it anyway)
