[bass player]

I agree with the previous correspondent that in general you get what you pay for (I am particularly fond of GK 2x12 cabinets), but the following may be one possible means of addressing your problem.

I bought a second-hand Behringer cab like yours for small gigs. I wanted something that I could easily wedge into the trunk of my sedan. The previous owner had experienced the same problem as you- the original speakers blew out. He replaced them with Eminence BP 102 Speakers, which cost $75 each. He also lowered the output of the horn by about half. With the new speakers, the cabinet is now rated at 400 watts at 4 ohms. I acquired the cabinet for roughly the cost of the Eminence speakers.

This modified cabinet sounds pretty respectable to my non-expert ears. I gather that this particular Eminence speaker is known for its low bass response and certainly, I get more low end from this set-up from any other 2x10 cabinet that I have tried. To me, many 2X10s are too focused on the mid-range: "all bark and no boom".

Again, I don't claim to be an expert and other forum members may have other suggestions. For example, some may wish to suggest other drivers.

I have paired this cabinet with a Gallien Kruger 800 RB head, by the way.
