I was looking at this idea of the Imperial to enhance my 4 channel SE84CS circle surround system, but I just don't have the room size for it (15X15 foot room)

I really want to build the Imperial design in a full range mono setup using a Mackie 1400i power amp for a party system (outdoors, garage music). I've got a pair of Cerwin Vega 154's and a bunch of Klipsch horn driver parts.

I saw a guy here that was wanting to put together a colledge dorm setup in mono on a triode..

Any ideas?
