... sound batting and/or weighting speakers ...


Hello to all... 

Need some thoughts and/or suggestions: I am using a pair of KEF Q1s - luv the sound, so much more full than I ever expected - and the driver has such cone extension that the speaker box really vibrates. Now - I am assuming that the vibration really = the possibility of distortion ( or a smearing at higher volumes, tonal deformity, if that is different) and I am wondering if this is more controllable by:
Adding more sound batting into the enclosure (thru the bass port)
Weighting the speakers with a bag of lead shot (?) over the top of the driver/cabinet box ( the cabinet is not flat on top, so I can't use a brick or solid weight; I'm guessing the weight should be something moldable, so the lead shot in a bag is possible if I can figure a way to affix it to the cabinet...)

Thoughts? Suggestions? Alternates?

Oh, I forgot one more solution. Get two subwoofers and take the bass away from those speakers.
There are three reasons enclosures dance, The cabinet is too light, the cabinet walls are not stiff enough and lastly the cabinet is not firmly fixed to the floor. #1 add mass. Put a granite slab on top of the speaker. You can get cut offs cheep at your local granite installer. #2 This one is tough. You would have to thicken the enclosure walls. At that point you may want to consider another speaker. #3 Put three spikes on the bottom of each speaker and jamb them right into the floor. This assumes your floor is reasonably solid. Good Luck.
