My speakers of choice are two Omni 15 Full Range for use as backline for bass guitar. I get the impression they sound awesome and I love their quirky look.
I'm using Eminence Kappa Pro 15LF-2 woofers, Alpha 6CBMRA mids & APT 80 tweeters.
All corners, handles, paint, crossover components, sockets etc. purchased ready

Sourced some lovely birch ply and had the larger cuts done at the wood yard. Using PL Premium!!
