The Performance Series is the universal line: enclosures sized to standard driver dimensions rather than to one specific model, for the buyer who wants a known-good box without waiting on a driver-specific build.
Every model is CNC cut in Tullahoma, Tennessee from Langboard Elite MDF, 3/4" (18mm), with V-groove and dado joinery and internal bracing as a series standard. The terminal cup is an ABS and carbon-fiber composite on a recessed mount with stainless hardware and copper ring terminals; dual and quad models run a single cup with the driver wiring made up internally, and several models ship pre-wired in 12-gauge OFC. Sealed models ship with polyfill installed. Warranty is one year limited.
Twenty-two models are live: 6", 8", 10", 12" and 15", fourteen sealed and eight ported, in single, dual, triple and quad driver configurations. Most are standard-orientation cabinets, with a small number of wedge and down-fire bodies in the line, so most vehicles have a direct fit without a custom build.
