The bass is all Audeze! No doubts there. Deep, tight and controlled with plenty of punch and rumble. I don't have the LCD-2F on hand and I've only heard them a few times (the last was a few weeks ago). But compared to the LCD-X, the EL-8s hold their own in the bass department. I did some quick back and forth with both and while the LCD-X have some of the very best bass I've heard, the EL-8's offer incredibly rich low frequencies!
