hi, everybody! Yes, I am basically a retard. what I do not know about inductance, etc. has filled volumes. Literally. Here's the problem... I have a Marshall cab, model 8412. It came with 4 Celestion G12L (8 ohm) speakers in it. I believe they are 25 watts, but don't know for sure. they only say G12L on the back. the frames are inked 8 ohm. They sound nice, but not great, IMO. I bought a pair of vintage Heppner 16 ohm alnico magnet speakers. Nice and light, they sound more mellow & fuller to me than the Celestion G12L's, more like Greenbacks. For the sake of this exercise, let's say all the speakers are rated the same for wattage (they probably aren't, but... close enough for rock & roll). I want to put the Heppners in the cab & still have it be 8 ohms. Can this be done? Can I wire the 2 G12L's in series to get 16 ohms, and the Heppners parallel to get 8 ohms and then... magically... not blow up my 100W RMS tube amp head and get... let's see... 8 + 16 = 24 / 2 = 12 ohms??? do you see my conumdrum? maybe if I add 2 - 4 ohm tweeters and hide them inside the cab & rip out their cones I could balance things ohm-wise? I know a TUBE AMP IS HAPPIER PUSHING A GREATER OHM LOAD (EX: 8 oHM OUTPUT HEAD, 16 OHM CAB = OK; 8 OHM OUPUT HEAD, 2 OHM CAB = FIRE) OOPS - SORRY FOR CAPS... here's what I did so far (really!)... I took one G12L out and put it in my Fender Deluxe 112 that had a blown 65 watt 8 ohm stock speaker. The Fender sounds great now, but I really want to use the Heppners in my Marshall cab. So far I have replaced the one G12L with the Heppner & wired it as the cab was originally. My knowledgable friend Krishna who refins & builds guitars said that it would be something like 12.5 ohms if I left it as is. ... could someone who speaks Retard help me? thanks!!
