The Palladium also comes equipped with 3x9-inch hybrid aluminum/Rohacell/Kevlar diaphragm woofers, a 4.5-inch inverted aluminum diaphragm midrange and a high-flow, low-restriction, die-cast aluminum midrange and woofer frames (with integrated heatsinks). The entire speaker is also tri-wired with gold-plated brass Klipsch binding posts (with gold-plated bus bars). These speakers are very expensive, priced at around $15,000 per pair.
