Overview

MK KIT Bookshelf Speaker Kit Pair with Knock-Down Cabinets

Simple Build, Big Sound

The MK KIT is designed to make building your own high-quality speakers both approachable and fun for do-it-yourselfers of every skill level. Inspired by the popular MK402X bookshelf speakers, this kit lets you assemble a proven design using carefully matched drivers, expert-tuned crossovers, and pair of precision cut knock-down enclosures. The result is a pair of speakers you build yourself that delivers the same smooth response, clean highs, and impressive bass that listeners enjoyed from the MK402X.

Every detail of the MK KIT is optimized for an enjoyable DIY experience. The precision-cut knock-down enclosures feature self-aligning rabbeted joints that simplify cabinet assembly and help ensure accurate panel alignment. The prewired, solder-free crossovers with plug-and-play connections eliminates guesswork and allows you to focus on the satisfaction of building rather than the complexity of wiring. From first glue-up to final listen, the MK KIT delivers hands-on craftsmanship backed by a carefully engineered speaker design that performs as good as it looks.

Controlled Bass and Smooth Midrange

Low frequencies are handled by the Dayton Audio TCP115-4 4″ Treated Paper Woofer, a driver well known for its impressive excursion and low-frequency capability in compact enclosures. Its low resonant frequency and smooth midrange response allow it to deliver surprisingly full bass while maintaining clarity and control through the critical vocal range. This driver is the ideal foundation for the MK KIT’s balanced sound signature.

Detailed, Non-Fatiguing Highs

High frequencies are reproduced by the Dayton Audio TD20F-4 3/4″ Soft Dome Tweeter. Despite its small size, this tweeter offers extremely flat response, wide dispersion, and low distortion thanks to its powerful neodymium motor. The result is clean, detailed treble that remains smooth and easy to listen to for long sessions, but never harsh or fatiguing.

Preassembled and Optimized Crossover

The MK KIT features a fully assembled and wired crossover network integrated into the terminal cup. Using a 3rd-order high-pass filter for the tweeter and a 2nd-order low-pass filter for the woofer, the crossover ensures each driver operates within its optimal range for cohesive, accurate sound. With solderless connectors and no loose components, final assembly is fast, clean, and beginner-friendly.

Easy Assembly, Endless Finish Options

The compact MDF knock-down enclosure is designed for easy assembly and precision cut. Rabbeted corner joints act as a built-in assembly jig, keeping panels aligned while creating strong, clean joints. The cabinet can be assembled with glue and clamped using simple masking tape, requiring only a Phillips-head screwdriver to complete the kit. Once built, the enclosure becomes a blank canvas that is perfect for paint, veneer, or custom finishes to match your décor or showcase your creativity.

Build, Listen, Enjoy

Whether you’re building your first speaker kit or looking for a compact, great-sounding DIY project, the MK KIT is a rewarding choice. Enjoy the satisfaction of assembling your own speakers, customizing their finish, and experiencing rich, balanced sound from a design engineered to perform. From desktop audio to small room listening, the MK KIT proves that great sound and a great DIY experience doesn’t have to be complicated.
