Da, MDF se lepi lepkom na bazi urea-formaldehida, koji je proglasen "verovatnim kancerogenim materijalom", ali i dalje su nacin zivota, ishrana, pusenje, industrijska zagadjenja, radijacija, nasledni faktori rizika.... osnovni izazivaci.

Svi "stapovi" su odvojeno seckani (!!)
Potrosili su 1532 table MDF-a od 2,5 cm !!
To je bilo tesko 90 tona (pre secenja) a posle secenja je ostalo 40 tona...
i nema dva stapa da su iste duzine...

Construction of the new room utilized 1,532 sheets of one-inch?thick medium-density fiberboard (MDF). Ninety tons of MDF were cut and milled to a final cut weight of 40 tons. Beginning with a room footprint of 36' x 25' x 27', the one-inch square MDF pegs come out of the walls and ceiling in lengths that vary from 6 to 40 inches ? and no two of the hundreds of thousands of ?tines? are the same length. The room uses 2D diffusion, whereby two-dimensional diffusers offer depth variation in two perpendicular directions, forming a lattice of divided cells or steps of varying depth. ?Studio C utilized the largest prime number sequence that has ever been actualized in a room,? notes Massenburg. ?Our prime number is 138,167.?

?The basic idea is that you walk in and very quickly you are listening to a musical balance. You are able to tell a story with a mix. The lows and the highs are easier to perceive because they have roughly the same ambience, the same reverberation time. We don?t have any fiberglass on the walls ? it absorbs largely at high frequencies and is less likely to absorb at low frequencies. Any absorption in this room is caused by several processes, including the air turbulence around all these edges, and the scattering of reflective sound from all these surfaces. Dr. D?Antonio has referred to our principle in action as ?ambechoic.?

?The room is conducive to accurate work because we have taken away the boundary effect by ?eliminating? the walls. The boundary effect is usually a speaker set away from the wall, which causes comb filtering because the sound hits the wall and bounces back at a different time than the direct signal from the speaker. Certain frequencies are canceled and certain frequencies are enforced, which is not a good idea in a critical listening environment.?
