Leather up on top, Cork plate on bottom


The leather is suede cowhide.  A product of the beef industry.  

2) The cork is neoprene cork blend. Rubberized cork, if you will.  An adhesive layer is applied to the cork, the leather is placed over top and the assembly is pressed between two plates of tempered glass.  An hour is given for the adhesive to cure in the press.  After cure, a center hole is punched with a hollow leather punch.  #9 (9/32 inches)  The perimeter is cut on a spin fixture to guarantee concentricity to the center hole.  The cork comes in a roll and must be ironed flat prior to lamination.  The suede is quite dense and tends to drape limply over any surface it is placed upon.   The assembled mat lies flat and has no tendency to warp or curl.  Another plus, no static has been observed.

3) Mat thickness: .100 inches  (Cork layer: .06  leather layer: .04)


I had previously tried this same suede leather with a felt bottom layer.  I found the sonics of that mat to be inferior to any of the Spotmat variants I had made.  Now using this leather but with cork as the bottom layer presents a different sonic entirely.  The mat offers the record a firm seating yet appears to damp well and offer low background noise similar to the later Spotmats I have tried.  Overall I have no complaints.  Sonics are good but do not rival those obtained with the best of my Spotmats.

This mat will work with a clamp but on the Thorens I prefer not to use one.
