  E22 Direct Servo subwoofer
Dual 12" sealed HT/music sub
Performance & Specifications

The frequency response of E22 is practically same as F12/F12SE with same extension frequency, damping factor, and rumble filter control.


Another aspect of getting a correct integration is phase alignment between the front speakers and the sub. We have written a guide on how to achieve a phase aligned subwoofer. E22 has a phase/delay adjustment knob. More >

Output, extension and user preferences

The bass extension switches allow the user to customize the deep bass extension in both frequency and Q value. A rumble filter is available to control cone excursion. For HT application, one can set the extension to 20hz, low damping, and rumble filter ON. For music one may prefer a 14hz, high damping, and rumble filter OFF.
