The crossovers used in PA speakers are typically designed more for power handling than that nth degree of que ne se quoi for ultra high fidelity. But that doesn’t mean that they can’t be adapted for home use with quite good results. This is just CD played on an Oppo95 through a Yamaha RX-Z9 RECEIVER in "Pure Direct" mode through two speakers (JBL 2241H, 18", JBL 2251J, 9-1/2", Heil AMT) easily filling a 5,000 cu ft volume with no sub or eq of any type being used.
