Hey fellow TB'rs. I need a lil advice...I have an older Avatar 4ohm 15" cab with the horn, and port/vent along the bottom of the cab. Its not the Kappa speaker I dont believe...I have never removed it and checked, but it farts like a mule with the low B string, and its very mid heavy in sound with little lows. So I am thinking about replacing the 15" driver with a 15 that has a lot more balls... any ideas? The cab is about 24x16x27. Also, I have been noodling with the idea of buying an Avatar 212 Neo with the blue tolex...and if I do I would like to cover the 15" cab in the blue tolex as well....any ideas where he gets his tolex covering? Thanks for any insight on this!
