My main limitation is height. I don't want anything over ~56" the chili's have me very interested...have not looked much at the fonken
thanks,

if you've seen the smaller Fonken design for FE127E, just think "big brother"

rough dimensions for the 167 version are:
950mx H (less any base plinth) x 274mm W x 238mm D Height includes approx 220mm of void lower cavity (sand or kitty litter fill for damping) - approx volume before bracing = 28 liters
4 slot ports flanking each side of the front baffle, so near wall mounting works well
A more complicated build than the Demetri, but much smaller footprint, and while I've yet to directly compare both, I'd assess the Fonken probably has superior imaging and slightly less but more well controlled midbass & down extension. This is certainly the case for the FE127E Mileva vs Fonken enclosures.
