A fully-optimised cinema layout, as a PDF, in minutes.
Free calculators covering speaker layout, amplifier power, room acoustics, projection and screen geometry. Each one runs in the browser, draws its results live at room scale, and produces an A4 PDF report you can hand straight to a client, installer, or contractor. No login, no charge.
