Building Speakers
David
on building speaker boxes for a guitar.
Second of all, I have a few questions that Im wondering if anyone can
answer right now.
-For a guitar, what brand of mid-price would be good? Im thinking of
a 2x10, maybe up to a 4x12 set up, depending on the price.
-Also, aside from the 1/4" jacks, would the crossover network be much
different from that of a regular speaker(regular being car or home
theater)? If so, how?

The nifty book from Groove Tubes is probably the best source of information
on various guitar amp cabinets. Some are open-backed, some are closed with
venting. They all sound different. Pick one you like the sound of and
copy it.

Take a look in the Antique Electronics Supply catalogue, and at some amps
that you like the sound of. They all sound different. Pick an amp you
like the sound of and use the configuration and box volume that they do.

Instrument amps normally have full-range speakers with no crossover. You
will occasionally find a crossover and a tweeter hanging off, but usually
pretty crudely with the main driver running full-range and a simple low-cut
on the tweeter. Pop open a cabinet you like the sound of and look inside.

Guitars have a reasonably narrow frequency range (at least compared
to some instruments) so you can do what most people do and just
use 2 or 4 identical drivers in whatever series/parallel arrangement
gives you an impedance that will match the amplifier - no crossover,
since you don't need to split the signal into component frequencies
to feed it to different drivers.
You should also bear in mind that some guitar cabs are open backed -
they don't use infinite baffle or ported designs like hi-fi speakers do. The
cab design can really colour the sound, so know what you like before
you get the screwdriver/wallet out.
Once upon a time I had a copy of Bernard Babani's (sp?) guide
to making loudspeaker cabs and it had some decent designs in it,
plus it only cost a few pounds UK. It's
Babani Publishing BP256 Intro to Speakers & Enclosures
About 7USD online from www.audioclassics.com.
People are fussy about drivers for guitars - see if you can ask
around, better still stick your nose around the back of the cabs
in your local music shop and see what they use. You can pay
whatever you want to for 12 inch drivers, from 20USD to
hundreds - you pays your money...
Hope this helps,
Glenn.
