15" Subwoofer Systems
Radian’s RP Series subwoofer systems are designed specifically for touring/live sound system applications. The RPS-115, single 15”, and RPS-215, a dual 15”, are designed to provide extended low-frequency response for high SPL live and playback applications.
Both the RPS-115 and RPS-215 feature a composite ribbed cone reinforced with Kevlar®. The 4” voice coil is edgewound aluminum for better transient response, but advanced adhesives give it the power handling capacity of more conventional copper voice coils. The RPS-115 and RPS-215 are capable of genuine 124-127 dB SPL, from 40 Hz to 500 Hz or 35 Hz to 500 Hz with 6 dB to spare for peak output.
Add this to a high-energy magnetic structure with a venturi cross section to increase efficient ventilation, and the result is a highly responsive subwoofer system that delivers robust bass at high SPLs.
