The drivers are HiVi RT1.3 tweeter and RS180P-8 woofer. The HiVi RT1.3 WE (round face plate) is a direct replacement.
This speaker uses a series crossover. The crossover transfer functions are shaped similar to the Neville Thiele Method™ (NTM). The slopes are 48dB /octave, eighth order.
I've been playing with a crossover for positioning this speaker on a shelf and near a wall. I've included this “tweaked” cross over along with the original.
If the original crossover sounds a bit fat, increase the insulation behind the woofer.
