The Ampeg PN-115HLF features a custom-designed 15-inch U.S. Eminence driver that can deliver the massive low end provided by high-output Ampeg bass heads. The lightweight neodymium woofer and compression driver are housed within a rugged 15mm birch plywood enclosure and shielded by a tough, powder-coated metal grille. It's perfect as a standalone unit or as an addition to the PN-210HLF or PN-410HLF. Designed and assembled in the U.S.A. and subject to a battery of post-assembly testing, the PN-115HLF delivers high-quality, high-output bass in a modern design that looks mean and plays meaner.
