VentedGeneral subwoofer design
Design a vented subwoofer box
Tune the box and port together, then check air speed, excursion below tuning and whether the duct will fit.
Cookbook
Work through a real speaker design
Each recipe starts with a real driver and real simulator output. Change the inputs, watch the trade-offs, then take the checks to the bench.

AnySystem integration
Choose amplifier power and headroom
Work backwards from the listening level to the voltage, excursion and thermal margin the system needs.
Passive radiatorCompact low-frequency systems
Design a passive radiator subwoofer
Choose radiator area and added mass without losing sight of travel on either diaphragm.
Sealed or ventedIn-vehicle systems
Design a car subwoofer
Keep the enclosure model separate from cabin gain, voltage limits and what you measure in the vehicle.
Two-wayDSP-based hi-fi
Design an active two-way speaker
Set the operating bands, match levels and build a crossover you can verify with measurements.
Two-wayHigh-output DSP systems
Design a high-efficiency active two-way
Bring the woofer, waveguide and crossover together without giving away directivity or protection.
