Greetings, Got a first time question for my esteemed bass buddies here at TB. I have a Behringer BT108 that is nice and lightweight and tonally has a lot to offer in a small amp however as appears to be the case with others that own this amp the speaker cannot handle the power at all. This starts to woof and fart at anything over 3. My question is is there an affordable 8" bass speaker that would be worthy as a replacement for the stock speaker keeping in mind this amp new is only worth $75. Thanks in advance for any input.
