Precision in
every dimension
Architecture, acoustics, and the engineering decisions behind sound that disappears into the room.
Q Factor Calculator: EQ Bandwidth, Octaves and Q
Your measurement software reports octaves; your equaliser asks for Q. Convert between them in both directions, see the filter drawn, and know when a narrow boost will cost you more than it fixes.
Speaker Crossover Calculator: Capacitor and Inductor Values
Crossover frequency, driver impedance and filter order give you the capacitor and inductor values. What the arithmetic cannot see is the driver impedance curve that moves the real corner.
SPL Calculator: How Loud Will Your Speakers Actually Play?
Sensitivity, power and distance decide the level at the seat. Doubling the amplifier buys 3 dB; halving the distance buys 6 dB. Calculate both, and the headroom the peaks need.
Room Mode Calculator: Every Frequency Your Room Fights You On
Calculate every axial, tangential and oblique mode from your room dimensions, with the Schroeder frequency, the widest modal gap, mode stacking and a Bonello criterion verdict.
Speaker Placement Calculator: Spacing, Coverage and Count
A calculator for both halves of the problem: how many ceiling speakers a room needs and how far apart they go, and where a stereo pair and the seat belong.
Subwoofer Placement: Calculate It Before You Crawl
Every guide gives a different fraction — a third, a fifth, sixty percent back. They are all describing one thing badly: a subwoofer standing on a pressure zero cannot excite that mode at all.
