TT in a cabinet

[Navin_R_Johnson]

I know this is the worst possible setup, but I recently moved my TT from on top of my entertainment center to inside the cabinet to pass WAF. It now sounds like my head is stuck in the mud.

Before I started to go crazy with damping materials and such I wanted a few opinions how to make the best of my arrangement.

The cabinet is very sturdy oak with a front door that has glass windows. The side pannels are fairly thin 1/8" (3mm) or so which I'm sure resonate badly when listening. The shelf is 1/2" (13mm) oak which I would also like to damp and reinforce.

Not sure if it makes a differance but, I'm on a concrete slab with wood floor. Also B&O turntable (which will soon be replaced with Rega)

Thanks,

Also look into isolation (feet). If you have access to a thick slab of stone or metal, that might get rid of some resonances just sticking it under the TT on the shelf. Good luck.

It's difficult to tell from your description, but would it be possible to construct a 'false shelf' within the cabinet, which is really a table solidly coupled to the concrete floor?

Ouch!!

Well we have to work with what we have, so these are my suggestions..make of them what you will.

1) I would deaden up the all surrounding panels (back, above shelve, ect.) as much as possible. Possibly the deadening material the car installers use to quite down car panel vibration would work here.

2) After making sure the shelf the TT is sitting on can take the load, I would make a tray that fit, and fill it with sand, and lay down a piece of Corian over the sand.

3) Have the spousal unit read this thread after it grows a bit, so that perhaps she can see the major effort her seemingly simple request requires to fulfil

Good luck,

Not possible. I don't think this would help much anyway, I think I should be more concened about the cabinet acting like a speeker box and trapping sound. I had exactley in mind what Casey said, sand filled box and load the interrior of the cabinet with automotive sound damping material. Maybe when my wife sees the price of damping material she'll change her mind

I would be, but getting a solid foundation is vital also.Since you had the TT sitting on top of the same cabinet before, and it seemed to work out, it sounds like it's a sturdy unit. I would also try to de-couple the whole cabinet (if possible) by putting some spiked feet on it.

Ah yes..especially if the expense were to somehow delay some other "essential".
