... 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?

G R Research No Rez. You will have to remove the drivers and cut to fit before installing.  I have done a few pairs of speakers with it, It will tighten up the bass and reduce the resonating.
Careful disassembly with Dynamat or similar product applied inside cabinet, overlapping seam on corners may help a bit.
Predominantly driver distortion, and tweaking, treating the cabinet will do little to address it. Move on, go find much better, because imo this is a very compromised design and there are worlds of improvement available on used and new market.
