CHR TOWER PART 1
In this video I report the first steps to build the CHR Towers. Intro, Main Idea, Goals, Test Boxes, FRD and ZMA files extraction, Material Selection.
The CHR Towers are a fantastic pair of powerful audio, low bass, high quality speakers. Made in Walnut Hardwood mixed with Euro-Ply and veneer this design relies on the Markaudio CHR-90 Full-range and the SB Acoustics SB15MFC30-8 Woofer. This is a two way speaker box that impresses by its power, SPL and High Fidelity performance, even using 5" woofer drivers and full-range drivers.
