The PHL 3003 is the best HiFi 10 " woofer available. It has good bass extension with high efficency. With very fast and tight bass, it is an excellent match with ribbons at 1500 Hz crossover. For best performance use a 43 liter vented enclosure for -3dB at 41 Hz. The 43 Hz port tube is 4" diameter by 8 " long. 200 watt amplifier = 113.5 dB.
