Right now I have a Carvin RL810T that I'm pushing with a Nemesis NA-650, and it sounds good but I'm lookin for an upgrade. I play metal in the c# standard range, and I don't really get the good thump or growl I've heard when playing out of other cabinets and I found it only goes down to 60Hz. I saw the Megoliath goes to 37Hz and has alot of great reviews, and it doesn't hurt my favorite bassist, Alex Webster, plays it too. I also found the Hartke HX810 has alot of outstanding reviews and it goes to 25Hz, but I have some speculations on what conditions to have it at to get that frequency. I just know I've narrowed it down to a toss up between these 2 cabs and was wondering if any one has any opinions on the 2 cabs to help me make a decision.
