I'm looking at upgrading to a GK setup. I'm really liking the Backline gear, particularly the 300w head. I know that I want a 1x15 cab and a 2x10 cab. My question is this: does the lack of a tweeter in the Backline gear make enough of a difference that I should shell out the cash for the full-on cab? For $715 hyperi can get the whole stack just using the backline gear. Should I shell out the extra $200 to get the 210SBX-II Bass Cab instead of the backline 210BLX-II cab? And if I did, would it be an ok match using the backline 115BLX-II and the 210SBX-II? Thx for your input!
