I know of only 2 'reviews' Alan's intial comments and one other by whom I can not recall (MichaelD perhaps) of the Accents and neither one mentioned a 'hole' in the sound. I believe the subs filter is actually able to reach up to 150hz.

Order them up and let us know, not many people run the Accents and if that sub doesn't cut it, you can always send it back and try one from another manufacturer.
