Hi, was wondering if anyone out there has tried both El Whappo and Whappo Jr. side by side. I was wondering if there is considerable difference in tone, volume, and bottom end between the two. Does that 15" make a big difference over the 12" in the Junior? I play mostly classic to current rock with a Lakland 55-02 and Thunderfunk TFB550 and am looking to replace my SWR 4x10 and Mesa 1x15 cabs with one 4 ohm cab that can punch, shake, and growl. Any other cabinet suggestions with my Thunderfunk also would be appreciated. Thanks!!!
