SpeakerCalc is an easy-to-use graphing calculator that supports do-it-yourself cabinet design for a woofer or subwoofer loudspeaker system. It makes use of the Thiele-Small parameters available from speaker manufacturers, and displays essential response curves such as sound intensity levels and cone excursion.
Analysis features:
– Sound pressure/intensity level curve
– System impedance curve
– Support for passive radiator designs as well as closed and ported enclosures
– Port airspeed and vent length
– Passive radiator mass output for resonance tuning
– Off-axis directivity attenuation calculation
– Alignment choices for ported (vented) and closed-box designs
Convenience features:
– Continuous parameter adjustment via slider, with instant response curve update
– Automatic parameter units conversions
– Creation, saving, and editing of designs
– Several built-in driver specifications, and easy entry of more
