Question about Paradigm Audio Players & Recorders
I have a pair of paradigm 9semk3 speakers that were playing okay (for being used with an underpowered stereo) the volue was turned up and they went flat. I have no buzzing, no funny sounds just a very flat, mono sounding, bassish sound. I know the tweeter on one isn't working at all but the tweeter on the other is. Both all 4 woofers seem to be responding. When the volume is cranked they move about 5/8 - 3/4 of an inch in and out like they always did, but the sound just isn't there. Just low somewhat muffled bassy sound. As I know zilch about the inner workings of speakers, I hope this is enough info. - Robar
I am trying to work out if you have damaged the speakers and amp too.
Have you tried a pair of headphones on the amp? If they sound ok then your amp is fine.
Assuming it is, then speakers have what's called crossover units in side each of them. This splits the sound into three parts. Bass, midrange, treble. The bass is handled by the woofer's, the midrange by a middle sized speaker or or it's combined with a tweeter, which of course handles the treble.
Connecting a 1.5 volt battery across any of the individual speakers will cause it to pop if working. If the speaker then is not getting sound then the crossover unit is to blame.
When you look at the crossover unit, it will have coils and capacitors (non polarised) on it. The bigger ones deal with the bass and the smaller ones treble. If you find a fault say on the crossover of the speaker, for example no treble comes out of it. Then start by replacing the capacitors. Use the same value as on the capacitor and remember they fit any way round.

If you have a Ohm Meter, check the resistance to the speakers. If it is very high, the speakers are burned, (or the crossover is (just capacitors, and resisters...cheap)). If it is close to 4 ohms check the wiring and connectors..to and at the speakers, most likly the receiver/amp is not blown.
