Achieving Real Bandwidth Beyond 20 kHz with a Loudspeaker System
There are now quite a number of so-called “super tweeter” products on the market, all claiming bandwidth beyond 20 kHz. However, this bandwidth is typically achieved only within a few degrees of the loudspeaker axis, and the real power bandwidth is much lower. The limiting factor in all piston-based designs is the “ka = 2” relationship between wave-number and radius. At 20 kHz, this results in the requirement that a is about 5 mm. By removing the requirement for the diaphragm to move as a piston, the “Balanced Mode Radiator (BMR)” allows the use of larger diaphragms, making the possibility of real power bandwidth beyond 20 kHz a practical reality.
