Default Recommendations for test equipment

I'd like to buy sufficient equipment to test my speaker and crossover designs. What do I need and where can I find mid-price equipment?

a soundcard -- for one thing.

a really nice instrument which sells for a song is the HP 3581 Wave Analyzer -- these sell for ~$50 and are always available on EBay. The HP3581 has 0.1uV sensitivity, a tracking generator, high and user-switchable selectivity, user-selectable tracking rates, etc. Dynamic range is 90dB -- so if you are doing distortion tests it isn't quite an Audio Precision item with 140dB of dynamic range, but you can make a 60dB passive notch filter and get really spectacular results. Occasionally these also show up via Canadian sellers so you will save on the post.

There is also Pen-Plotter output on the rear terminals -- if you have even a modicum of programming skills you can connect the pen-plotter output to an ADC card (like the MacDAC) and log the data on your computer.

A couple years ago when I broke my ankle (badly -- immobile for 3 months) I scanned and OCR'd the manual -- a few of the links need "repairing" but you'll get the basic idea -- http://www.tech-diy.com/HP3581/hp3581.htm
