In Reply to: Ken, have you noticed the Lack Triangular Side Table? posted by FlatEarth on October 24, 2001 at 17:11:18:
Hi Flat,
Re:" I haven't seen the inside construction of one of these tops, but I believe they are a skin over a matrix or lattice."The way that these things are made is pretty cool.Brilliant,even.
They insert the precut outer veneers into a precision mould and pressure inject a mix of expanding urethane foam and woodchips into the cavity between the veneer.The foam then expands and securely bonds the top,sidewalls and bottom sheets together.
The entire structure thus forms an extremely lightweight and surprisingly sturdy laminated shell, operating in shear, over an energy absorbant core.
The random nature of the wood particles in their sizes,shapes,densities,positions and orientation ensures broadband damping qualities.
When used as an audio isolation device,the Lack table operates by constrained layer principles.
Conceptually, the top functions in a manner very similar to Neuance and Torlyte, tho obviously IKEA never intented that the tables would be used for audio specific applications and lacks the refinement of the purpose built devices.
Nonetheless,with just a few simple modifications,it's musical and stomps more than a few very popular dedicated rack systems in performance.
The ever-popular DIY Flexy doesn't even register on the charts.Best,
Ken

But vastly inferior to the brilliantly engineered Neuance shelf I think. Wouldn't you agree ?
Ken,Thanks very much for the technical low down on the Lack.
It makes one wonder how on earth Ikea have been able to maintain carrying them at a measly 15 bucks for all these many years. Mega mass production combined with low shipping mass and DIY assembly, I suppose. Sales of the delicious meatball lunch plates, must help balance it all out come month end.
BTW, I have been lurking about your website recently. Been thinking about replacing the top shelves of my Sound Org stands (for TT and CD in main system). They are what I call second generation originals, the ones with the adjustable bottom spikes. They are the 3 and 2 shelf versions, ~24.5" and ~14.5" high (minus spikes) respectively.
I also have a Sound Org wall shelf (again in the original style but the later version with the odd fore/aft levelling hex screws), and was wondering whether I should upgrade and reinstate it for turntable support duty rather than the 2 shelf floor stand. That would allow the turntable to once again have a dedicated support without my recently acquired tuner, that is currently below the TT on the 2 shelf, ending up on the floor. The CD could then have the lower floor stand all to itself and the tuner could take the CDs current spot on top of the 3 shelf. Gee, I think that I just answered my own question there.
However, your recommendations regarding the suitablity of the Sound Orgs for platform upgrades would be of interest to me. Any suggestions?
Regards,
Flat
Hi Flat,
The very first Neuance was tested using the original Sound Org first gen tabletop stand and those earlier units(especially the wall support) remain amoungst the most desirable of supporting frameworks for Neuance applications to this day.
I still use a pair of 2nd gen 3-tiers like yours in my home system.They have the inexplicably rare spike decoupling feature for every shelf(via the pointed tabs) unlike the Targets, Standesign, etc. rack systems which must have their lower shelves adapted for Neuance( an easy task yet still unacceptable for many).
Best,
Kenps-I'd go with the wall support for the turntable,myself.That 2 tier is a back breaker.

Hi Ken,A while ago I was given a link from here to a rather long discussion on Audiogon about the use of the Lack table as TT supports, and even to built an equiptment stand using several of them. Due to a virus crashing my system, and even taking out the backup, I have lost the URL. Do you, or any other regulars here know it? Saves you wasting your time and repeating yourself. I need to make a rack for my components and the Lack stand seem like a good cheap idea. I have previously used heavy sandboxes for TT supports, but my current abode is a rental with 'soft' hardwood trampolines for flooring and my 300kg sandboxes will destroy them. This will be an interesting experiment.
By the way, how much weight will the Lack's support? I have a Gyro and a Townshend Rock as TTs.
I have enjoyed your input to this debate of TT supports to be very interesting since I found the asylum, especially as you are generously giving your knowlrdge and experience, even though you are competing with that commercailly. Thanks for sharing.
Cheers

The major concerns are that it is a thin shelled structure and the veneer can become punctured by sharp spikes or cones if you use them with your kit and also that the design is not particularly well able to handle heavy sideloading.
If you use cones under your components,they must either be of the rounded tip variety like the DH Labs or BDR or you must use a spike protector of some sort to spread the load over a broader surface area(this esp. applies to stacking of Lack tables when used as a rack system).
You can use the free formica sample swatches found at larger home improvement stores stuck down with 3M #714NA general purpose carpet tape to improvise spike protector pads.They can be chosen to match the Lack and also used beneath spiked stands to protect flooring.
With heavy components you should definately add bracing to the legs as sideloading could cause a failure at the junction between the legs and the top. The simple 90 degree angle brackets found at hardware stores will work fine.They should also be glued as well as screwed into place.Best,
Ken

> That 2 tier is a back breaker. <I agree, however, it does force one to kneel appropriately at the altar of vinyl worship :D. I practically have to lie face down on the floor to tune the tuner (Naim), thankfully I usually only listen to CBC Radio 2 (like your NPR) as most of the rest sound crap.
Thanks again for your advice. I will mull over the options for a bit and then do something. I really do hate the hassle of mounting the wall shelf, but my gut instincts tell me that it would be the best option performance wise. I originally bought the SO wall shelf as my table was located quite near to the speakers, and in too tight of a space to accomodiate a dedicated floor stand.
Since taking it down, a friend has kindly given me his old Target TT1, and by chance I recently stumbled upon a used Rega wall shelf at the local dealers for $50. that I just couldn't pass up. In summary, I now have quite a collection of various types lying about the place. I guess that it is time to get the tools out again.
BTW, is that your Roxy X on Mana wall iron in your site pics? I always did like the original Xerses, but haven't yet had an opportunity to hear any of the later models.

that's my baby-
a full boat Roksan Xerxes 10/Artemiz rig
w/DS1.5 psu and XPS5 controller
on a fully Neuanced Mana Phase 2 Reference wall shelf
and currently running an ebony bodied Dynavector Karat Nova.
I like it.
