Direct-Radiator Loudspeaker Systems with High Bl
In an earlier paper (AES 113th #5651) we showed the basic consequences of a dramatic increase in the motor strength Bl of a driver, as it relates to the efficiency of the loudspeaker and the effect on amplifier dissipation. Here we study the effect of reducing the cabinet size, increasing the mass of the cone, and the use of vented systems or those with passive radiators. A high Bl-value has a positive influence on many aspects of loudspeaker systems that have traditionally been relegated to standard recipes. A glance at some products available today suggests that at least some of the loudspeaker industry is aware of these ideas.
