what type of subwoofer is good for ribbons

try to find a panel subwoofer, such as the enigma or sound lab b2.

if you want to optimize coherence, a panel sub is the way to go.

unfortunately there are very few of them, and they may not extend low enough to satisfy some bass enthusiasts.

the problem with panels and cone subs is the dispersion patterns of each driver type is unique.

i think i can hear the discontinuity of a panel and cone sub in all cases in a blindfold test.

i have heard many panels with subs and i have heard two different speakers in each case.

there is another issue. subs have a cabinet. there is a considerable amount of wood which may have a resonant frequency, whereas a panel sub has less wood and its dispersion characteristics are closer to the main speaker.
