[sci.electronics] Speaker components source and design info wanted

chan@ames.arc.nasa.gov (Jeff Chan) (11/20/88)

Here are my recommendations for speaker parts/kits/info:

Two very extensive and competitively priced speaker component dealers
are Madisound Speaker Components, 8608 University Green, Box 4283
Madison, Wisconsin 53711 (608) 831-3433, and A & S Speakers, 3170 23rd 
Street, San Francisco, CA 94110, (415) 641-4573.  A & S is now open
Saturdays (great for us Bay Area folks!).  Both offer high quality 
drivers from around the world.

Audio Concepts (901 South 4th Street, La Crossse, WI 54601 
1 (800) 346-9183 for catalogs and orders) is also a good source for 
high quality raw parts.  They also offer some good speaker kits, 
including full kits with cabinets and parts only kits (ie build your 
own cabinet).

Speaker Builder Magazine (PO Box 494, Peterborough, New Hampshire 03458
(603) 924-9464) publishes plans for speakers, and through Old Colony
Sound Lab (PO Box 243, Peterborough, NH 03458 (603) 924-6371 or -6526)
offers many books on building speakers and on audio electronics in
general.  Old Colony also sells some high quality electronic parts
and kits for amps, preamps and test equipment from the pages of their
other publication, The Audio Amateur.  

I've just started a subscription to both magazines (they give you 
issues back to the start of the year when you sign up) and enjoy the 
articles and the spirit behind them.  The articles come from audio
professionals like William Johnson of Conrad Johnson or Nelson Pass
of Threshold and also from intelligent amateurs, and the equipment
is generally directed at an audience of music-oriented audiophiles
who are also capable of building their own.

It was pretty reasonable for the magazines to split about 6 years ago,
since more people are able to design their own speakers than design
their own class-a mosfet amps or preamps.  So the speaker designs
seem to come from a broader range of people than the electronics designs.
Accordingly, SB comes out six time a year while TAA is a quarterly.
Both cost $20 per year.

On a related note, OCSL stocks electronics parts and kits probably 
because speaker components are fewer in number and easier to get.  For 
example, printed circuit boards usually are available for the TAA projects.  
I guess I'm trying to justify them having two separate magazines.  The
subject matter really are different in character.  

I'm enjoying both magazines and recommend them.  The mods I did on my
disc player have made it sound fantastic (try it yourself before you
jump to any comments about subjectism), and the ideas came from Jung
via TAA, in addition to Hi Fi News (UK) and the New Jersey Audio Society
newsletter (via our local audio group).  This brings up another point.

The publishers of the magazines continue to support local audiophile
groups (by offering free start-up ads).  There are groups in most major 
areas and they are another source of good information and discussion.  
See the classifieds in the back of the magazines.

Have to go; happy listening,
