CHR Tower Speakers Part 2 | Best DIY Speaker Build 2022 | Markaudio CHR-90 + SB Acoustics Woofers

CHR TOWER PART 2

In this video I report the last steps to build the CHR Towers. Woodworking; measurements, cutting, gluing and finishing the boxes plus results, crossovers and frequency response curves.

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-ranges.
