Backside of one FrugalArray showing wiring and crossover. Tweeter wiring is silver plated teflon insulated copper. Notice how the woofer cutouts are chamfered to minimize cavity resonances.
New speakers for the Righteous Reverend Dr Otis Futhermucker, Mississippi Delta blues player and pastor of the church of our Mother of Perpetual Orgasm in LaGrange Texas. These Dayton Audio MTM's use Dayton 7" Reference Series woofers with a 1.125" Reference Series tweeter. The crossover is 3rd order for the woofers and 4th order for the tweeter, using air core inductors, metallized polypropylene caps, and non-inductive resistors. They are great looking and heavenly sounding for the Reverend.
