Check every component works together.
TV, receiver, speakers, sub, HDMI cables — CinemaConfig validates impedance, bandwidth, Atmos layouts, and room acoustics across your entire signal chain.
What CinemaConfig validates
Six checks that run every time you add a component
Impedance validation
Checks AVR-to-speaker impedance across all channels
HDMI bandwidth audit
Validates HDMI 2.1 bandwidth by resolution and refresh rate
Power draw calculation
Calculates total system power draw against your circuit capacity
Room mode analysis
Detects room mode clusters before you place your sub
Clipping risk detection
Flags receiver clipping risk at reference listening levels
Sensitivity match
Verifies speaker sensitivity match to your room volume
Every check runs against your actual components — impedance ratings, HDMI spec versions, wattage, room dimensions.
What most calculators miss
A projector throw calculator tells you where to put your projector. It doesn't tell you whether your receiver will clip your speakers at high volume, or whether your HDMI cable can carry 4K/120Hz to your display. That's what CinemaConfig does.
Impedance validation
Checks whether your receiver can drive your speakers at your chosen impedance without thermal throttling.
HDMI bandwidth audit
Verifies your cable and source can deliver 4K/120Hz or 8K/60Hz based on the actual HDMI specification.
Power draw calculation
Adds up total system watts and flags if you're close to your circuit breaker limit.
Room mode analysis
Calculates your room's resonant frequencies and the Bolt Area ratio. You won't find this on a generic calculator site.
Clipping risk detection
Checks amplifier power against speaker sensitivity and room volume. Catches mismatches before you buy.
Full signal chain
Models the entire signal path from source to speaker, not just one component in isolation.
How it works
Plan every piece of your system
Pick your display
The centerpiece of every home theater. We help you choose the right screen size for your seating distance, compare OLED vs LED for your room's lighting, and check that your source chain supports the resolution you're paying for.
Build your sound
Going from TV speakers to a real surround system is the biggest upgrade you'll make. Configure anything from a 2.1 soundbar setup to a full 7.2.4 Atmos layout — we validate that your receiver can actually drive the speakers you pick.
Connect it all through your receiver
The AV receiver is the most confusing purchase for newcomers. We check impedance matching, HDMI bandwidth for your sources, eARC support for your TV, and enough channels for your speaker layout. No more guessing if things are compatible.
Optimize for your room
Your room determines everything — viewing distance, speaker placement, where bass builds up, and how much acoustic treatment you need. Enter your dimensions and we calculate it all: room modes, RT60, first reflections, and ideal subwoofer placement.
