About the CCB-8

The HSU Research CCB-8 is a two-way passive bookshelf speaker designed in collaboration with Don Keele, utilizing a unique constant directivity coaxial driver where a 1-inch aluminum dome tweeter is mounted behind the 8-inch polypropylene cone woofer, hidden under an acoustically transparent dust cap. This point-source design eliminates lobing effects, provides even dispersion up to 15 degrees off-axis vertically, horizontally, or diagonally, and enhances efficiency in higher frequencies. The vented MDF enclosure supports variable tuning via port plugs for flexibility in dynamic range and output. It excels in musical detail, transient performance, wide dispersion, and value, often paired with subwoofers like HSU's VTF series for full-range systems. Build quality is excellent with a magnetic rotatable grille, and it's versatile for upright or side placement. Reviews praise its holographic imaging, dynamics, and performance rivaling pricier speakers[1][3][5][6][7].
