Hi. I just bought a used SWR gloiath III cab along side a Hartke HA 3500. When I got the rig home and started to push it, it seemed to 'fart out' on almost any note below E (the cab is rated to 40Hz and E is about 41Hz is the the problem?). I started looking into the cab the see is i could find any problems and found something a little interesting. The Goliath III was stamped 8 ohms on the backplate. I pulled all four speakers to look for and defects and found none. I threw a meter across the speakers to have a look at the voice coils and all four speakers read 4Ohms individually (is this normal for the goliath III). The horn in the cab is stamped 8 ohms and reads 8 ohms on the meter. When I reinstalled all four speakers and the horn I used the exact wiring that scheme it had before. The problem persists. I did a little more testing and found that the entire cab tests at 4 ohms, not 8 like it says on the backplate. I also checked for an out of phase speaker with a good ole 9 volt battery, and found one. These two findings (the cab reading 4 ohms, and the out of phase speaker) leads me to think that the previous owner has tweaked with the wiring. Does anyone know where i can come by a correct wiring schematic to run this thing at 8 ohms. Another question: I'm pushing the cab with the hartke 3500 that I bought with it. I know the head will run perfectly fine at 4 ohms, but it seems that all of the literature surrounding the amp suggests that you are best off with 2 8 ohm cabs to get to 4 ohms. Is this true, or can I wire the goliath to run at 4 ohms, and get the most out of the amp (or does it matter at all). I really appreciate any help with this. There is nothing more disheartening than dropping all of your savings into a rig that your not happy with. I think the rig gets a great tone if I stay away from the b string, but that is not what I had in mind. I am well within the return/exchange period of the dealer, but I'd like to just sort it out and keep the equipment. Thanks!
