SM1-PC
The passive crossover is a 4-WAY, 6 filter design with a woofer Zobel network.
12db/Octave Butterworth for all filters.
3% MKP Mylar Capacitors for accuracy over the life of the loudspeaker.
Custom wound air core inductors.
I designed the SM1-PC loudspeakers with performance in mind. Once I had the design ready which took a couple of years, I selected the drivers based on their specification required for the design.
The SM1-PC are a 4-way sealed cabinet design using 3/4" MDF for the housing and internal construction consisting of bracing and glued dado locked framing for structural rigidity and fiberglass filled fully damped cabinet.
