The Simplexx Series by Bill Fitzmaurice
are the perfect combination of performance and ease of construction
These cabinets can be built by anyone, minimal tools required
SpeakerHardware kits make them a painless start for the beginning builder,
or the experienced one who needs simple high performing speakers.
-
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.
-
These cabs aren’t difficult to build, but they still feature engineering that even ‘boutique’ cabs can’t lay claim to.
