Calculators
All calculators run entirely in your browser. Your inputs never leave your device. Every formula is shown openly on the page.
- Simulation Enclosure designer Simulate sealed and bass reflex enclosures: frequency response, maximum SPL, excursion and port air velocity – with verified driver data.
- Calculator Calculate a bass reflex port – length from volume and tuning Calculates the length of round bass reflex ports from net volume, tuning frequency, diameter and number – with end correction depending on mounting.
- Calculator Calculate propagation time and delay – from distance and temperature Calculates from distance and air temperature how long sound takes to travel – in milliseconds and in samples at 48 and 96 kHz.
- Calculator Calculate power, voltage and current at the loudspeaker Converts power and impedance into voltage and current and shows the level gain over 1 W – with sensitivity, also the theoretical level at 1 m.
- Calculator Adding levels – dB incoherent and in phase Adds up to four levels – once for independent sources (incoherent) and once for in-phase sources such as closely stacked subwoofers.
- Calculator Calculate wavelength – with quarter wave and temperature Calculates the speed of sound, the wavelength and the half and quarter wavelength from frequency and air temperature.
