Racks, how do you support your equipment?

I'm not sure if this is the correct place for this but here goes :) I'm sure the mods will put it in it's place...

As i have no in progress projects right now i thought i'd show you my rack. The idea behind it was to prevent everything from becoming dusty & to at least attempt to prevent the sound from the speakers vibrating everything.

This is still work in progress as i'll be incorporating a PS Audio P600 powerplant to drive most of the front end (though this will be external). I'll also be fitting a nice air filter to prevent dust getting in to all the components. Right now it doesn't stop that, it seriously reduces it though :)

Here we go with a few pics... First up the whole rack, there are certain components missing (Pioneer CTF950 cassette deck for one). No DVD player either (Denon dvd 2930). Blu ray player will go in to shortly...I'm in love with the Krell DT10 top right :worship:


It was a bit of a PITA to build this rack, the shelves were easy though simply because i made a jig to make them all exactly the same. All the shelves can slide up & down the rack & be locked into position so any size of front end component can be fitted in, that is unless it's over 19" wide :D Excuse the dust, just shows how long it has been since the cassette deck was in there ;)


Here we have the central front shelf support. I happened to have a load of cross threaded bolts with square nuts so i simply made a channel that the nuts could slide in & another layer of MDF so they'd clamp tight. Works very well.


All the shelves get fitted from the top & then slide down to where i want them to be & then bolted in place.

On each shelf there is a rather large & heavy what i assume to be concrete slab which has been painted to make it look a tad better. These are 18" by 18" & are standard fare from a garden centre. To decouple the slab fom the shelves there are 4 x 1/2" thick felt feet, one in each corner.


I don't tend to use a record deck very often, hense the thing is at the bottom. Just to aid my loading of records i added a 12" fluorescent tube just above it. This is switched on when the power switch on the record deck is turned on, makes sense to me lol. You can also see the air intakes of the rack. These will eventually be covered with some kind of speaker grill cloth to prevent dust ingress.


When things get warm we have some fan cooling, these are very quiet though as they are channeled from the middle of the rack to the outside & back again front & back.


Lastly the air outputs of the rack, the same is also on the rear of the rack itself. You might notice 4 of Yamahas finest beryllium midrange units that are going to be used in a speaker project hopefully coming soon :)


The whole thing ends up sealed and i'm using a load of secondary double glazing to seal up the front of it. Works very well indeed, it might have been a PITA to make but the result was better than i expected. Not only does my equipment stay cleaner for longer, it also sounds better due to less vibration ;)

That's it for now, just thought i'd share a bit...

Nice rack.

Funny, I usually say that to the girls.

Attachment 160462 Cheers Cal

As i say though it's still work in progress. Some stuff will be removed & new stuff added. My present preamp (Classe DR5) will be removed & an ex dem Audio Research MP1 will be going in as a replacement, this means the Harmon Kardon AVR5500 will also be redundant & removed as the MP1 will take the place of that to.

DCX2496 will be added for active front speakers & various other bits & pieces.

One thing i didn't mention is the real PITA of moving or removing anything :eek: Simply put each shelf & component above what i want to change needs to be disconnected & removed to get to the connections at the back of whatever it is that's being moved or changed.

I wish i had thought about that earlier, but as it is it doesn't happen very often thankfully :) The thing is it does exactly what i wanted it to do, so i can put up with some quirkiness.

Bests, Mark.

Acoustat Rack
 
Hi there being an Acoustat fan since the early 80s my friend rebuilt a pair of 1+1s for me and a small but heavy audio rack that i named my Acoustat rack the only thing that's from Acoustat on that rack is a metal sticker that say's Acoustat here are a few pictures.

Work Almost Done

Nicely done MrAcoustat :)

Nothing so fancy for me... an of the shelf (ha :)) rack. One of my pet hates is seeing loads of wires so made a loom up for this.

One question I thought of starting a thread for... how much weight can you put on tempered glass shelves... mine are supported by just 4 small stick pads on the main framework.

I'm not surprised. In all these racks prettiness trumps vibration control :cool:

I just sit things on my sub (lucky it's a bipole, or things would fall off...).

At least you guys have shelves.

I'm pretty sure tempered glass will happily support quite a bit of weight as long as it's not subjected to massive vibration. Unless you happen to be using a jack hammer nearby i think you'll be ok ;) That or tiny contact area for the equipment if it weighs some may do some damage.

On the contrary, in my own case the audio equipment is virtually sealed off from the environment. The rack is 3/4" MDF with rather large reinforcements which support the shelves & then the plinths are decoupled by 1/2" thick felt.

I think it works rather well :magnify:

Sorry i haven't been about people, i have been suffering with my blasted back again :rolleyes: I keep saying i'm used to it (guess i should be since 1990) but it still takes me by surprise when it gets really bad :(

I'll see if i can get some pictures of a friends setup which looks very similar to MrAcoustats & his friends racks. Very nice to :)

Not sure what felt achieves as a vibration reducing layer but i fear not much under 100Hz.

Sorry to hear about your back; is it a slipped disk?
