Hi, I play in a couple bands that gig regularly and moving equipment is not really a problem exept for my Mesa-Boogie 2x15 deisel. That thing is sooo heavy and it has casters but to carry it up stairs, into vans, ect... is backbreaking and painfull. Even with two people it is difficult. The amp I have is a Trace Elliot v-type 600H and it puts out 600 watts into 4ohms. It only has one speaker out as well so i can only hook up one cab to it. Please help me to find a 4ohm cab can be carried easily, can handle 500-700watts and can spread out the bass to small to basket ball court sizes clubs. Oh... and is under $800. Thanks in advance.
