Reality Check! Are like make / model loudspeakers consistent?

How consistent are production loudspeakers? Measured data is used to compare the responses of 12 units of the same make/model.

Lessons from the RF Analyzer

The proper instrument can allow the unseen to become observable. Dale uses his HP RF analyzer to demonstrate some wireless mic issues that audio people must deal with everyday.

Pseudo Stereo – When Stereo isn't possible or practical "spaciousness" may be an adequate substitute

When true stereo is not feasible or possible, “spaciousness” can be achieved with a relatively simple playback setup.

Compression Driver Specifications

Does a lower impedance driver have higher sensitivity? This case study gives some clues.

Loudspeaker Sensitivity – What's a Watt, Anyway?

Sensitivity and sound pressure level are not the same thing. Charlie shows why.
