Stop guessing.

Will your AVR drive those 4-ohm towers? Is your projector throw right for a 120" screen at that distance? Does your sub need a dedicated circuit? Find out before you buy.
From room to rack
Start with your room
Dimensions, construction tier, ambient light. The engine computes your finished interior after drywall and framing — because that's what your screen and speakers actually see.
Assemble your signal chain
AVR, amp, speakers, sub, display, sources. Each component you add gets validated against everything else in real time — impedance mismatches, HDMI bandwidth, power draw, all of it.
Validate everything
Projector throw distance, amplifier headroom, viewing distance for your screen size, room mode predictions. Share the build, export to Reddit, or save and come back.
Real-time compatibility validation
Every time you add or swap a component, the engine re-checks the entire signal chain. HDMI port counts, speaker impedance against your amp's rated load, 4K/HDR passthrough, eARC requirements, power draw against your circuit capacity. Problems surface immediately — not after you've unboxed everything.
8 calculators
Projector throw, amplifier headroom, viewing distance, room modes, speaker wire gauge, RT60 decay — all from your room's finished dimensions.
Multi-retailer pricing
Amazon, Crutchfield, B&H Photo. Prices refresh automatically with staleness detection so you're not comparing yesterday's numbers.
