This is technically a full range speaker and can be used by itself, or crossed over at lower frequencies to be used as a woofer.
Condition: Used - Excellent
From Electro Voice:
Electro-Voice Models SP15 and SPISB are massive 15-inch reproducers of deluxe construction. They offer outstanding performance as full-range loudspeakers or as low-frequency drivers in multiway systems. The E-V Radax coaxial principle employed in these speakers offers an extended high-frequency response beyond the normal capability of ordinary 15-inch loudspeakers: and the combination of outstanding magnetic structure, edgewise wound voice coil, and viscous-damped cloth cone suspension makes possible an unusually low cone resonance and extended low-frequency response. The Model SP15 incorporates an exclusive E-V
circuit which dramatically improves high-frequency response through control of speaker impedance at high frequencies. Action of this unique circuit and adjustment of the speaker's high-frequency response is determined by the setting of an auxiliary brilliance control.
