I recently came into a 90's era Messa Boogie 2x15 Diesel (pretty sure it's the diesel line) cab with a blown driver. I was expecting to find EV's in there, but found one stamped frame Eminence 15 with a voice coil rub, and a newer Eminence Delta 15 in good working order. My local Speaker supplier is out of stock on the Delta 15 , and recomended the Kappa 15 (in stock) as a suitable replacement. Any cab guru's thoughts on if this would work well, or be appropriate would be appreciated. Will the Kappa 15 work well in this aplication?
