I have two Eminence Legend CA154s and I'd like to optimize them. I have a schematic that allows me to run them seperately at 4ohms or together at 8, which meets my purposes. What I'd like to know is what cab best suits these drivers? - prefab/existing cab or home build? - sealed or ported? Weight doesn't worry me, but a smaller form factor would be nice. Any ideas or recommendations? Currently they are in a shallow Peavey 2x15, but I'd like to see if I could do better.
