Accuton AS190-9-252 Cell Concept Driver - Keramik Bass
AS190-9-252

The AS190-9-252 is an 8 inch bass driver with aluminum honeycomb sandwich dome, being the first in an entirely new approach to accuton speaker design. An ideal acoustical center has been achieved, which is identical with our CELL tweeters and midranges. Its novel designed overhung motor combines the advantages of traditional over- and underhung designs, delivering high linear excursion and ultra low distortion. An exceptionally hard aluminum sandwich dome was developed for the CELL bass drivers that allows for negligible delay and energy storage. The hidden surround serves for reduced outer diameter and linear excursion of +/- 9mm. A new developed spider shape makes huge excursion without compression possible. We recommend our AS190-9-252 for an application from 30 Hz  – 1000 Hz.
