< p> The new Voice Optimized B1c has the efficiency and output of a classic bullet tweeter with an updated waveguide improving off axis dispersion. The titanium diaphragm is driven with an improved, higher energy neodymium motor, resulting in higher sensitivity and overall output. A new cast aluminum wave-guide with integrated mesh grill gives the B1c a higher-end aesthetic with added diaphragm protection.< /p>
