The 6510 1" throat diameter compression driver is designed to reproduce high frequencymaterial. The 6510 utilizes a 4" spherical titanium dome, suspended in a ellipsoidally stabilized geometric surround. The diaphragm is made of pure titanium, which eliminates the possibility of dome fracture and allows the driver to sustain higher power levels for longer periods of time. This driver is capable of producing usable response up to 20kHz.
