Please Note: The actual outer diameter of this driver is 9.84." 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 maximum excursion of +/- 16mm. A newly developed spider shape makes huge excursion without compression possible. We recommend our AS250-8-555 for an application from 20 Hz - 600 Hz.

CELL concept drivers are characterized by the following main features:

• Same acoustic center for tweeters and midranges for time coherency in a flat front
• Perfect signal settle and piston behavior of the dome even close to the dome resonance
• Acoustically decoupled clamping mechanism providing fast and easy assembly into a circular hole
• Small outer diameter
• Very low distortion - in the magnitude of electronic devices - even at high power levels
• Steady decay of higher order harmonics
• High bandwidth
