OK I have a Genz Benz 2-10 XB-2 4 ohms 250 watts. I recently got a Eden 2-12XLT that is 8ohms and 400 watts. I am ruming them through a Hartke HA-7000 When i turn the gain up tp about 5 and the volume up to about 5 and play a open B the Eden makes a fluttering type sound. It is only getting 240 watts max. While the Genz benz is getting 35 watts max and handles the low B at that volume with no problem. the Genz benz has a frequency of 50-16K Hz +/- 3db and the Eden 44 hz to 14 Khz +/- 2db. WHy would the Eden be doing this? Could my amp clipping on the 8 ohm load but the identicle amp not be clipping on the 4 ohm load when being pushed the same. Do the speakers need to be reconed? Is there anything I can do about this? at low volumes this is my dream sound.. I just cant run in my band with 3 guitarists with this farting sound. Any help will be much appreciated.
