Number One SPH-170C 6.50" Midrange Speaker 120W Max. 8ohm

Especially high-quality HiFi bass speakers and HiFi bass-midrange speakers of perfect manufacturing quality and elegant design, with aluminium basket, carbon fibre cone and especially long excursion, an impulsive bass reproduction of low fundamental resonance of partly surprisingly small cabinets. High-end bass-midrange speaker, 120WMAX, 8Ω,

with an excellently dampened cone and extra long excursion, remarkably low distortion for a particularly natural reproduction, very low limit frequency, especially suitable as a bass-midrange speaker in 2-way combinations, yet small volume requirements.
