I currently have Peavey Nitrobass head (450w 2ohm, 300w 4ohm, 160watt 8ohm) connected in parallel to a 1x15" Eminence Kappa 4ohm speaker cab and a 2x10" sheffield speaker 4ohm(Peavey 210tvx) cab. Now I really don't get alot of this impedance and SPL stuff, so go easy on me here... I'm looking to sell my rig and go for something newer and more powerful but with a quality finish! It wouldn't also be so bad if it wasn't quite as large, my stack is almost as tall as me. Money is an issue and i'll looking for something with a good range. I looked at the Behringer power pack, consisting of a BX3000T Ultr bass head (300watt @ 4ohm) a BA410 (4x10" 1000watt apparently 40hm) and finally a BA115 (1x15" 600watt 8ohm) because of its extremely good price. Would this be any louder? Does mixing the ohmage make a problem? BA410 info BX3000T Head BA115 Anyone have a good setup they can advise on? I think Harkte and Ampeg are out of my budget range I have a 5 string Ibanez EDC715 and I play a lot of rock/metal so it's got to handle distortion. Thanks all, Joel.
