Here's what I know after speaking to Mr. Lyon...

I just finished assembling an Ikea Lyte rack using the Oak veneered Lack side tables. The legs of the oak veneered side tables are solid, albeit particle board. Obviously, this made the process simpler and quicker. My experience is corroborated by inmates who have observed that the oak finish has solid legs. One inmate commented that the oak veneered table is the only one with solid legs. I can't confirm this.

I exchanged 3 or 4 emails with Ken Lyon (of NeuanceAudio and original designer of the Ikea Lyte Rack) before and after building the rack. Here's what he had to say about the current construction methods of these tables:

"What appears to be the issue regarding all the variations of the IKEA Lack is that the sidetables apparently are now being outsourced to several different companies by geographic regions and each of these subcontractors have a slightly different manner in which they meet IKEA's "criteria". Most of the differences have been in the legs however your description of the "short fill time" (see explanation in paragraph below) would indicate that what you have is probably a newer variant that I've been hearing about with more frequency over the past several years- a top that contains a fibre "lattice" honeycomb rather than an open architecture or foam/chip injection. What I find most interesting is that even with all these diverse constructions, the performance and benefits gained are nearly identical regardless of the exact construction utilised, and imo makes for a convincing argument for the application of rigid, low mass, rapid dissipation support & isolation [rack]."

Above, Ken's reference to "short fill time" was in reply to my observation that the table would only accept short bursts of polyurethane foam inserted into several holes drilled into the bottom of each table top (I endeavored to insert foam under the impression that the tabletop was hollow). The table's cavity would quickly pressurize after about 3 seconds of spraying and, consequently, would resurface out of the same hole instead of filling the outer/corner recesses of the shelf's cavity. My experience seems consistent with Ken's understanding that, at least some variants of these tables, have some type of honeycomb core. I am hopeful that I did achieve constrained layer damping because I think I was able to bridge the top and bottom layers of the shelf with foam. In a separate AA post, Ken commented that it would be best not to uniformally fill the table's cavity with foam, but only parts of it.
