By increasing the woofer size, and using the woofer cone as the horn for the tweeter, we have greatly improved the performance of our better than $350,000 bookshelf speakers. The new CCB-8 is 3 dB more sensitive, has more uniform off axis response (no lobing), and higher power handling while retaining all the excellent micro dynamics of the HB-1s. You can listen for hours without fatigue. It's holographic soundstage makes you feel you are at the the original performance venue. The music floats in the air, totally detached from the speakers. Customers gets the goose bumps listening to these speakers.
