A milliós tétel igaz, amennyiben 4 irányú motorizált maszkolással rendelkező vásznat veszel.

Ezzel ellentétben a legjobb minőségű 3m széles szőtt hangáteresztő vászon anyagok 150-300K-ból megvannak, aminek az ára kb duplázódik, ha a keretet nem saját kezűleg készíted el, hanem megrendeled.

Itt lehet olvasni a 2016-os vásznak minőségéről: https://www.accucalav.com/wp-content/uploads/accucal_front_projection_screen_report.pdf

A mikroperforált vásznak képe és hangja is rossz. A linkelt tesztben 5-6m távolságig látszottak a lukak, és 6dB hangnyomás vesztést mértek a frekvencia sáv végén.

It should be noted many of the screen materials on the previous pages are available in a perforated version from manufacturers like Stewart Filmscreen. These micro perforated products will have acoustical properties similar to the Audio Vision product below, but offer the option of substantial screen gain which can be very beneficial.

Audio Vision - This material was very color neutral. It does have a little more texture than the Classic Cinema White and an obvious hole pattern. The hole pattern was visible up to 15 feet. It had a slight sheen to it which was visible on images infrequently at 9 feet. Treble was 6db down at 20 kHz compared to the level at 2 kHz. The audio response effect was a relatively smooth loss from 4kHz to 20kHz. This material is not recommended because of the high frequency loss and lack of significant screen gain to offset that loss.
