Had a go with supports...

CDS2/52/250 on phase 2 Mana. Please don't blame the Mana, shoot the 250!

 

A 250 drives Kans quite nicely.

 

Yes, but expecting a small box like the Obelisks to reproduce convincing low bass is, er, optimistic. I actually quite liked them, not too bad at all. Taking off the wheels might help the muddle in the middle.

Performing structural alterations to the house in order to try to get one's speakers to work properly is an interesting approach!

 

Agree completely - must be a first!

I doubt I will fiollow Alex's advice and fill the cavity under my floor with concrete BUT that said the floor is a bit loose, the house is 70 years old and nothing has ever been done under the floorboards. I may try stregthening the spars (not the right name I know) that go under the boards. Anybody tried that?

Cheers

Jason

 

No, not tried. 'Er downstairs might object.

Wheels off, Mana under, sorted would be my unoriginal contribution. Might be a bit cheaper too.

Jason, you +/- Alex must come up. I don't bite, Paul D said so (or did he?)
