Fun quote:
"Whenever I need inspiration for my projects I turn to the budget
speaker pages in my 1970 Allied Radio catalog."

A snippet:
>>"Are you looking for low-budget, two- and three-way DIY loudspeaker
designs? You've found the place! This speaker building page is for those
interested in building do-It yourself speaker projects employing drivers
of moderate to very moderate cost. The typical driver cost for one of my
speaker designs runs between $10 and $50 per speaker. The crossover uses
around $15 in parts, sometimes less. The box is made from MDF and can be
built with simple power tools, ****table circular saw, saber saw, sander
and drill. Boxes cost about $10-15 per speaker in MDF (Medium Density
Fiberboard, readily available at places like Lowes and Home Depot),
decking screws and glue, and are not beyond the capability of a very
casual woodworker.
Computer modeling using a program called WinISD was used to develop
basic box sizes for the drivers employed, using the so-called T/S
parameters. Crossover design was not done on the computer, other than
to use a spreadsheet program to select crossover components based on
the frequencies I wanted to try crossing drivers. Beyond that,
crossover designs were modified by running repeated experiments using
different crossover component values and configurations, and comparing
the sound with a speaker using the best previous configuration. They
should not be regarded as the perfect crossover for the drivers, but
they are the best sounding configuration I have been able to find so
far for each speaker design. So again, if you want a highly
sophisticated crossover based on a lot of computer modeling, you
should check out any number of other sites."<<
