Designed by John Suhr and manufactured to exacting standards specified by John, the CAA 4x12 cabinet is constructed of 13-ply Baltic Birch plywood and features dovetail corners for the ultimate in strength and roadworthiness. As of now, we only offer the straight-face 4x12 with the black grille although the slant cabinet and the salt-and-pepper grille have been offered in the past by Custom Audio Electronics. The CAA 4x12 has great projection with a focused punch and strong tight lows. All cabinets are not created equal! We recommend the Celestion G12M-25 Greenback speakers for those seeking a classic sound with a lot of warmth and singing highs. The Celestion G12H30 Anniversary speakers are recommended for a tighter response and midrange focus. For modern high-gain applications and all-around versatility, it's hard to beat the Celestion V30’s. Just add speakers!
