Hey all, I'll get straight to the point.

I have an Infinity Kappa 63.5i three-way speaker hooked up with the supplied crossover which seperates the highs and the lows. Recently, the speaker seems to have gotten messed up, not sure whats wrong, but no low frequencies are being produced by the speaker. The only way to get the lows to come up is when i apply force to the woofer, but this is only like a 5 second temporary fix. The highs coming out of the tweeters are perfect, nothing wrong with them at all.

The system consists of the stock non-bose head unit, and a Profile 4 channel amplifier. I was pretty sure that the amplifer was not pushing the speaker to its peak, as the peak is stated by Infinity as 225Watts and RMS is 75W. The only thing I think would have messed something up is when i tried to force in another pair of speaker wire into the channel which powered the now defunct Infinity speaker, as a way to try and send power to a single 12" polk subwoofer, this attempt failed and I unplugged the subwoofer from the channel. Could i have somehow created a short and blew the woofer out?

Either way, is the speaker done for, or could there be any other problem. All the wiring is perfect, the crossovers work fine. Anything else I should troubleshoot? All the other 3 speakers in the system work fine on each of the 3 channels, and 4 channel seems to still be good as the highs as reproduced nicely.

Once again, the speaker is not reproducing lows, and i was wondering if the speaker is (or woofer) is not good anymore. Please help.

 

You pushing on the cone = you changing the resistance of the speaker. I.E. Its blown.

Damn, now I'm going to order another pair of kappas to replace the messed up one, but is there any methods or steps I should go through to find out if anything might be screwing around with my speakers or that particular channel on the amp?

Generally blowing a speaker would mean having the volume/gains up really high or something of the sort, i'm assuming, not an expert on how these things work or even how they can really mess up.

 

Distortion is whatll blow the speaker, just make sure the amp is tuned correctly.
