Simplexx 15 Flat Pack Bass/Key

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.
