The Accuton AS190-9-251 is a bass speaker with a diameter of 190 mm and an aluminum honeycomb sandwich diaphragm. The new design enables an ideal acoustic center, identical to those of Accuton's CELL tweeters and midrange drivers.
The novel overhang construction combines the advantages of traditional overhang and underhang designs, delivering high linear excursion with extremely low distortion. A particularly hard aluminum sandwich diaphragm was developed for the CELL bass drivers, allowing for very low delay and energy storage. The hidden centering reduces the overall outer diameter and allows for a linear mechanical excursion of up to +/- 16 mm. A newly developed centering spider allows for large excursion without compression. We recommend our Accuton AS190-9-251 for applications from 30 Hz - 1000 Hz.
