Simplexx is our line of easy to build bass reflex cabinets.
All Simplexx cabs feature braced half-inch plywood construction, for better performance with lighter weight than commercial cabs. All feature corner located ports, for stronger construction with less weight than round or slot ports. Corner ports also sound better than round or slot ports, as their placement equalizes air pressure inside the cabinet, preventing cone rock at high levels. Two driver bass and keyboard cabs feature vertically stacked woofers and dual vertically stacked tweeters, for maximum horizontal dispersion with no high frequency beaming or comb filtering. S10 and S12 PA tops feature Eminence coaxial drivers. These cabs aren’t difficult to build, but they still feature engineering that even ‘boutique’ cabs can’t lay claim to.
