C-Note MT Bookshelf Speaker Components Only Kit

How do you build great sounding speakers on a budget? Easy! The C-Note bookshelf speaker kit delivers accurate response, incredible imaging, and a surprising amount of bass -- all for an unbeatable price! All the components you need are included to complete this speaker building project: drivers, port tubes, crossover components, crossover circuit boards, binding posts, screws, and wire.

The Drivers

Dayton Audio's DSA135-8 5" Designer Series woofer is used for the midrange and low frequencies. With an aluminum cone and a powerful motor designed for low distortion, this woofer produces bass with authority while remaining smooth through the midrange frequencies. The high frequencies are handled by the ND25FW-4 1" soft dome tweeter , also from Dayton Audio. This waveguide-loaded tweeter controls high frequency dispersion for smooth off axis response and natural sound. Another advantage of the waveguide design is that it allows the voice coil to set further back from the baffle for an almost perfect time alignment with the woofer.

The Crossover

Dividing the frequencies between the drivers is a 6 component 2-way crossover network. Polypropylene caps, air core inductors, and low inductance resistors are used, allowing this network to pass audio with minimal effect to the original signal. The C-Note kit now includes dual sided printed circuit boards making the crossover assembly and installation easier than ever.
