I recommend you all find a way to audition a pair of PowerPoints on the ceiling at "normal" listening geometry with subwoofers configured on the floor beneath them driven by your hi-fi amp. That's my studio setup. I expect you to fall in love.

I got good result tweaking my loudspeaker (Diapason Adamantes MKI in my second system) enclosure taping the inner with thick lead plates (two millimeters) coupled with polymer glue in order to get a sort of sandwich that allow to lower the resonance frequency, actually it works well, the bass extension, focus and and solidity is audibly improved.

Good work. I should comment that lowering the RF in itself hurts things. However, it is likely that you also decreased the resonances for net gain in quieting the cabinet.
