Other manufacturers praise the use of a low crossover point in order to minimize the inherent problems crossovers present. Why do your products use higher frequencies?
A. Actually we don’t. There is more to crossovers than just the crossover point. Understand that the woofer doesn’t stop at the crossover point, its frequency response slowly declines beyond it. Most passive crossovers roll off at 12 dB/octave. Since the woofer’s output must be at least 24 dB below that of the ESL before it can be considered to be out of the picture, the woofer will operate at least a couple of octaves above the crossover point in most speaker systems. The selection of a crossover point involves many compromises having to do with the effect of dipole phase cancellation, clarity, equalization, output levels, and the woofer’s ability to handle midrange frequencies. Sanders Sound Systems’ advanced Transmission Line woofers are able to operate flawlessly, well above the frequency range of most woofers. Crossover points and slopes are carefully selected to be sure that the woofers are operated within their capabilities as proven by the flawless integration for which our spe
