hey guys, i was hoping to pick your brain yet again: pretty simple situation, i got myself a bassbreaker 15. I love the thing; for all 6 string purposes sounds awesome, at the right volume without disturbing my flatmates. now, i run a KSR ceres with it for metal, and it sounds great, but it seems that the amp, and particularly the speaker, does not handle extreme lows very well. When i play an 8 string thru it, it sometimes "farts" loudly for an instant before going back to normal. so, 3 questions basically. 1. do you think a speaker swap would improve the lower end handling? 2. if so, what speaker would you recommend? 3. what would i need to consider to swap it? (first speaker swap for me, so im not sure about all the Ohms thing and whatnot, what specs do i need to pay attention on the bassbreaker, would it be a straight "disconnect old, connect new" kinda thing?" thank you all in advance.
