Don't forget that on a K-110 the black and red terminals are reversed from what they are on most speakers, so you may have your phase backwards. That would not, however, cause the problem you are describing.
Thank you very much for your input!! :thumbs up:
Ok, so if I have this straight, on a K-110 red is actually black and black is red. Yes/no? Anyway, when I first hooked it up I thought is sounded rather anemic so I reversed the wires and the sound radically improved. So I do believe I have the polarity correct. The amp was purchased new about six months ago and while I did recently change the tubes there was no crackle noise with the stock Fender speaker. I even gave the amp a full run through before I changed the speaker out, so I believe the issue is related to this speaker because it did not happen with the stock speaker.
Is it possible that the stock speaker was crappy enough that the crackling was not evident and the JBL is revealing enough that the problem is now audible whereas it was not before?
Also, the cable that came with the amp that goes from the speaker out to the the speaker (1/4" connector to +/- termination) is comprised of a very low quality molded 1/4" connector and very high gauge copper wire that is essentially lamp cord - could that be causing the problem? The cable was originally terminated with female F (or T1) push-on connectors that connected to the male F( T1) blade-style connectors on the speaker. I snipped the F connectors off, stripped a bit of the insulation from the wires and inserted the ends into the spring-loaded connectors on the JBL.
So, whaddya think? New speaker cable? Amp issue that was masked by a crappy speaker? I don't have a power conditioner so potential RFI/EMI interference?
As a final note, while the K-110 fits into the cabinet, it is a "fits like a glove" type of fit. At the very center point of the chassis is a small silver colored box that hangs down.It is obviously some part of the amp circuitry but I have no idea what. Anyway, the basket of the speaker clears it, but it JUST BARELY clears it. The two are not touching but the clearance is literally the width of two medium guitar pics. If the basket was about 2mm higher it would not have cleared the chassis. Could the extremely close proximity of the two be causing the crackle? Also, the back panel strip that I had to remove to ch
