Hi Jack.
I’d be pleased to do that when the foam arrives.
ASG have given a delivery date of after 14th April. As I’m replacing the crossovers as well, it will be a full service on the SBL’s so hopefully all will go well. Will post pics in the thread when done.
Regards. Tim.
Yes, of course, that’s fine to post pictures - we could even make an FAQ on it, if suitable.
@Richard.Dane and @TimUK
Thank you both. I’m looking forward to it!
Hi Jack.
Just to temper your expectations, i haven’t done this before either, so I’m just winging it.
Will try to give you as much info as possible, & will highlight any problems i encounter.
If it’s ok with Richard, I’ll give details of the company & how much the foam has cost (including vat & delivery).
Ross (the guy i spoke to at ASG) comes across as a really nice guy who’s willing to help anyone with the foam.
Regards. Tim.
I would also be winging it. That’s exactly the perspective I need!
That’s good to know Jack. 
Regards. Tim.
Are there any benefits to using an appropriate weight / volume of lead-shot to sit at the bottom of the base cabinet, as to further aid vibration damping?
Suggesting a modest 2 kg of lead shot with each SBL, not sure how voluminous that would be but assuming only an inch or so (?)
I can understand why a manufacture wouldn’t find it desirable when sold as a brand new product; extra weight with transit, and then the setting up of an already heavy to move speaker, plus health and safety issues with toxicity.
However with existing SBLs in well set-up home situations this maybe a fairly easy mod to do if gains are there for the taking, as long as the user is content with each SBL weighing in a couple of kilo more, and the cost of buying and the safe handling of the lead shot.
Hi Debs.
I for one wouldn’t recommend doing that, adding anything that will alter the volume of the base box will probably affect the sound reproduction as well.
Reducing the volume of what is just a passive resonance box would reduce the bass frequency of the speaker.
With the SBL’s known for being (shall we say) a bit light in the bass department, you could make things worse by reducing its volume.
Also, getting the loading mass into the bottom box could be tricky, having seen that there is a filter of sorts covering the port.
I would have thought that for adding extra stability to the speakers, the spikes would suffice (especially if placed onto a wooden floor or thick carpet).
I suppose you could try attaching some extra weight (in a bag for instance) to the underside of the speakers. That won’t affect the sound quality, but would (with the extra weight) give you more stability.
At least that will be easy to revert to the original specs, if it doesn’t work out for you.
I hope you find an answer for your problem & let us know how you get on.
Regards. Tim.
I’d echo what Tim says above. I had some Acoustic Energy speakers years ago, they had a dedicated chamber in the bottom of the cabinet for lead shot. I wouldn’t want to put it within the acoustic loading chamber, as that would be defeating the original design.

Neil.
