I actually bought a pair of Peerless 12" 830669 (IIRC) for sealed boxes for use with the Alpair 7 drivers. Had picked up the components for a first order passive crossover. Got sick and never finished the project.Alpair 7 should probably have a 15 ohm resistor across the speaker (in parallel, not series) to help stabilize the impedance so that a single cap can be used. 160uf will put the first order crossover point at around 220hz with a 15 ohm parallel resistor. Put a 20 ohm resistor across the woofer with a 4.0 mH choke in series and the crossover should be pretty close.
At least that was my design.
