Free AV Tools & Calculators
Calculators and utilities for planning an AV install — amplifier power, cable gauge, subwoofer placement, screen size and projector setup. They run in your browser, need no account, and store nothing.

Free AV Calculators, Built From the Jobs We Do
These are the tools we reach for on real installations, put online because the arithmetic behind a good room is not secret and getting it wrong is expensive. Every one of them works in the browser, stores nothing, and needs no sign-up.
Most of them fall into two groups. The audio tools cover what a system needs and where it goes — how much amplifier power a room calls for, what gauge a cable run wants before resistance starts eating the signal, and where low frequencies will and will not sum cleanly once the speakers are in the room. The projection tools cover the picture: how big a screen should be for the distance you sit at, whether a projector has the resolution to justify that size, and whether the image is actually square on the screen once it is hung. Falcon Player sits outside both — it reviews XbotGo sports camera footage and has nothing to do with a theater.
Where the tools disagree with a rule of thumb, they tend to be right and the rule of thumb tends to be a simplification of them. Where the published standards disagree with each other — and on viewing distance they do — the tools say so rather than picking a winner.
Frequently Asked Questions
Are these tools free?
Yes, all of them, with no account and no limit. They run entirely in your browser and nothing you enter is sent anywhere or stored.
Do I need to be a customer to use them?
No. They are public and most of the people using them are nowhere near South Carolina. If you are local and want the room built rather than calculated, get in touch.
How accurate are the numbers?
The math is exact; the assumptions are where the judgment lives, and each tool states its own. They are sized for planning decisions — what to buy, where to sit, what gauge to pull — not as a substitute for measuring a finished room.
Can I save a setup and come back to it?
Yes. The same calculators let you save named presets, and export them to a file so your settings are safeguarded outside the browser — clearing site data, switching browsers or moving to a new computer will not lose them. Presets are kept in your own browser and the export file stays with you; nothing is uploaded to us.
Do the tools work on a phone?
Yes, they all work on a phone, but they are designed for a desktop first. Several of them show side-by-side comparisons and reference tables that simply have more room to breathe on a larger screen, so if you are planning rather than checking something on site, use a computer.
