... 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?

amg56,
I'm guessing you're in Australia, have you heard Mike Lenehan's ML5's up on the Gold Coast? stereo.net.au forums are full of members reviews of his loudspeakers. I have his ML2 Ultimates with the HD3 and 4mm steel plates lining the enclousure.
I've found high praises on Kyron Audio. I might have go have a listen if I'm down in Crow-eaters territory again.

We don't know the motivation of the OP; whether to band-aid the speakers or dump them to move up. It would help if there was more direction given as to the ultimate goal. 

I found the Lenehan ML1 Bookshelf Speaker I reviewed for Dagogo.com to be a wonderful product, well built, with good sound. Read my review of it at Dagogo.com 


@rixthetrick I am in Queensland, Brisbane actually. Kyron Audio is in SA though. Where are you?

Thank you for your suggestions: will try bag of sand, internally on the speaker cabinet floor (easy to insert thru the port on the front) and the speakers came with a foam plugs and removable grills.
