Subwoofer Box Calculators Software and Applications.

|

Audio Subwoofer Design Software	Design software for solving the required calculations for building bandpass, sealed and vented speaker and subwoofer box designs. Build, plan and design your own custom sub boxes and speaker enclosures for home, car, truck, boat and sport utility vehicle applications.
Subwoofer Box Comparison Calculator	Compare sealed, ported and bandpass enclosure parameters in one program.
4th Order Bandpass Subwoofer Box Calculator	Solve parameters related to fourth order bandpass enclosures, sealed rear chamber Q, passband ripple, low and high frequency rolloff, driver resonance frequency, driver total Q, front chamber port tuning frequency, overall bandwidth, ported front and sealed rear chamber net volume, equivalent air compliance, cone effective radiation area, cone peak linear displacement, cone diameter plus one third of surround, maximum air volume displaced by cone excursion, port or vent length and minimum diameter, end correction factor and sensitivity gain.
Crossover Calculator	Online application for solving inductor and capacitor values for first, second, third and fourth order passive crossover systems for two way speaker systems (high and low pass filters). Solutions include Butterworth, Linkwitz-Riley, Bessel, Chebychev, Legendre, Gaussian and Linear-phase type calculations.
Sealed Closed Subwoofer Box Calculator	Solve parameters related to closed boxes, speaker system total Q, driver total Q, system resonance frequency, driver resonance frequency, equivalent air compliance, minus three decibel half power frequency, net box internal volume, free air reference efficiency, driver electrical Q, peak sound pressure level, maximum air volume displaced by cone excursion, cone effective radiation area, cone peak linear displacement, cone diameter plus one third of surround, air density, sound speed in air, maximum displacement limited linear power output, maximum driver power input, required electrical input to achieve Par, efficiency bandwidth product and air volume with same acoustic compliance as the driver suspension.
Sealed Designer Online	Online design software for solving closed and sealed subwoofer box designs. Includes a plot for comparing decibels versus frequency response.
Sound Wave Calculator	Solve problems in relationship to sound pressure level (SPL), point source sound intensity, emitted power, frequency, wavelength, decibels, watts, least audible sound, human ear hearing threshold, damage and noise pollution level (NPL).
Subwoofer Vent Calculator	Online design software tool for solving the length of a subwoofer vent or port given diameter, number of ports, volume of enclosure, tuning frequency and end correction factor. Determine the minimum port diameter to prevent port wind noise.
Vented Ported Subwoofer Box Calculator	Solve parameters related to vented and ported enclosures, free air reference efficiency, cone effective radiation area, cone peak linear displacement, cone diameter plus one third of surround, box volume, driver electrical Q, driver resonance frequency, efficiency bandwidth product, driver total Q, tuning frequency, minus three decibel half power frequency, driver resonance frequency, peak sound pressure level, port or vent length and minimum diameter, end correction factor and air volume with same acoustic compliance as the driver suspension.
