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.
