The C-Sharp powered bookshelf speaker kit makes it easy to build your own self-contained stereo system. This compact speaker pair provides extremely flat response with much more low end than you would expect from a speaker this small. In addition, the C-Sharp's controlled dispersion delivers pinpoint imaging with a surprisingly wide soundstage. The built-in Lepai LP40PA plate amplifier makes the C-Sharp a true stand alone system allowing you to easily connect through Bluetooth or line-in to play audio directly from any phone, tablet, computer, or TV.

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.

The Lepai LP40PA consists of two main parts, the plate amplifier and the control panel. Producing up to 2 x 20 watts RMS (2 x 40 watts peak) the LP40PA has enough power to drive the C-Sharp to impressive output levels for serious room filling sound. The 4-button control panel gives you the ability to select between Bluetooth and 3.5 mm inputs and adjust volume up and down. In addition, when in Bluetooth mode the control panel allows you to skip track forward and back, along with play and pause.

The solid MDF enclosure's 1/2" panels are all CNC milled to tight tolerances, ensuring easy construction. The surface mounted woofer is easy to install, while the flush mounted tweeter provides a sleek appearance. With all necessary cutouts for the drivers, ports, amp, control panel, and terminal cup this kit is extremely easy to assemble.
