Accuton AS250-8-552 ALUMINIUM-SANDWICH DRIVER
AS250-8-552
The
AS250-8-552
is an 11 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 +/- 16mm. A new developed spider shape makes huge excursion without compression possible.
We recommend our
AS250-8-552
for an application from 20 Hz – 600 Hz.
