Without proper measurements, it is difficult to tune a loudspeaker to behave in an intended manner. Initial design considerations will guide the behavior of the loudspeaker but measurements will help with tuning the stuffing, crossover and baffle step diffraction.

The biggest difficulty in getting good measurements is the space in which the measurements take place. Almost no one has access to a proper anechoic chamber so some concessions must be made. A few strategies for recording will be outlined below, followed by my efforts to capture meaningful data.

I use a behringer microphone and mixer connected to my computer running RoomEQ Wizard.

A pieced together amplifier using a power supply, miniDSP active crossover/preamp, and 4 channel power amplifier allows me test drivers and crossover configurations before buying and building discrete crossovers. This has been built into an old technics amp case that uses the original volume knob and power switch.
