Audio Calculators
Where to Start
Designing a two-channel listening room? Start with the 2-Channel Stereo Placement & Toe-In Calculator and Amplifier & Headphone Power Calculator. Building a surround or Dolby Atmos room? Start with the Room Size & Acoustic Ratios and Speaker & Subwoofer Sizing.
Audio & Speaker Calculators
2-Channel Stereo Speaker Placement & Toe-In Calculator
Dial in your stereo triangle, speaker toe-in angle, front/side boundary clearance, and phantom-center sweet spot for two-channel hi-fi listening.
Open CalculatorAmplifier Power & Speaker / Headphone SPL Calculator
Calculate continuous wattage, transient peak headroom, RMS voltage, and current draw for passive speakers or audiophile headphones.
Open CalculatorTurntable Tonearm & Cartridge Resonance Calculator
Calculate your tonearm and phono cartridge mechanical resonance frequency (targeting the 8–12 Hz ideal tracking zone) from effective arm mass, cartridge weight, fasteners, and dynamic compliance.
Open CalculatorStylus Lifespan, Wear & Replacement Calculator
Pick your stylus profile and how many hours a week you listen to see how long the diamond lasts, when audible wear typically begins, and when to budget for a replacement.
Open CalculatorPhono Preamp Gain & Cartridge Loading Calculator
Calculate optimal MM/MC phono stage gain (dB), input load resistance (Ω/kΩ), load capacitance (pF), 20 dB groove overload headroom, and step-up transformer ratios.
Open CalculatorSubwoofer Crossover & Phase Alignment Calculator
Find the ideal high-pass/low-pass crossover frequency (Hz), filter slope, phase angle (0°–180°), and AVR distance offset from your main speaker F3 and subwoofer distance.
Open CalculatorSpeaker & Subwoofer Sizing Calculator
Calculate your room cubic volume to find the ideal subwoofer count, driver size, speaker sensitivity target, and channel configuration.
Open CalculatorSpeaker Placement Calculator (5.1 & 7.1)
Enter your room dimensions and listening position to get exact speaker coordinates in feet and inches with a scaled top-down diagram.
Open CalculatorDolby Atmos Speaker Angle Calculator
Calculate overhead speaker distances, side-view elevation angles, and ceiling coordinates for .2 and .4 Dolby Atmos setups.
Open CalculatorAcoustic Panels & Bass Trap Calculator
Determine how many 2'×4' absorption panels and corner bass traps your listening room needs based on surface area, wall material, and use.
Open CalculatorCable Length & Speaker Wire Gauge Calculator
Calculate per-channel speaker wire runs, total spool footage, recommended AWG wire gauge, subwoofer LFE cable, and HDMI run lengths.
Open CalculatorAudio Delay, Lip-Sync & Speaker Time-Alignment Calculator
Convert speaker distance offsets, display processing lag, and video frame rates (23.976–120 fps) into exact millisecond (ms) delay settings for your AVR or processor.
Open CalculatorSystem & Room Planning Tools
Evaluate acoustic room ratios and standing-wave modes, build a timbre-matched component spec sheet, or map a scale architectural diagram of your room.
Interactive Audiophile Quiz
Gear category, budget, sound, room, and recipient: five questions and you are matched with curated speakers, headphones, amplifiers, and acoustic upgrades.
Launch PlannerListening Room & Home Theater Size & Ratio Calculator
Calculate minimum and ideal room dimensions, acoustic aspect ratios (Sepmeyer, Louden & Golden Section), and fundamental axial standing-wave modes.
Launch PlannerBuild Your Home Theater & Audio System
Select your room dimensions, channel configuration, and tier to generate a timbre-matched speaker, subwoofer, and receiver specification sheet.
Launch PlannerInteractive Room Layout Planner
Generate a scale room blueprint showing viewing-distance seating, a 38% acoustic starting point for comparison, an equal-distance speaker arc, and first-reflection points.
Launch PlannerSafe SPL Listening Dose & Digital Audio Bitrate Calculator
Calculate safe daily listening duration and noise dose (NIOSH/WHO 85 dB & OSHA 90 dB curves) alongside uncompressed PCM, FLAC, and DSD audio bitrate and storage requirements.
