I've aquired this speaker panel:

(as well as a **** load of vintage components along with it) and I'm hopefully going to build a speaker cabinet out of it. My amp has a 4 Ohm, and 8 Ohm speaker output, so I need to wire it to be one of these. Could someone please help me wire up this speaker diagram?

Ditch the 7ohm speaker.

Parallel the two 40w speakers together.
Parallel the 8w and the 12w together
Then series the two loads.

Should equal out to 8ohms.

Lat time I did this it didn't turn out well. Sure it gave me much more output, but the sound quality left much to be desired. Hopefully your's turns out better than mine.
Do you use a BR-600?

yeah, I was wondering why the hell there would need to be a 7 Ohm speaker in there....It would only mess with me. I'll get rid of it.
Thanks for the help so far.
Let me re-do this diagram to see if I get it.

Edit: this is a Yamaha speaker panel taken from a vintage organ, I figured it'd make a fun project, and a learning experience. I also further modded my Tube Screamer and V847 with the use of the componts inside. This thing was like a gold mine!

^well what kind of speakers did you use?
crappy speakers=crappy sound....


I used a set of speakers out of a pair of panasonic 100 watt speakers. I've also tried doing this a couple of other ways with different sets. Maybe my amp just plain sucks...

Basically you want one red and one black lead, altogether.



Like so. Green circle is the speaker cup.

so they were hi-fi stereo speakers?
that's you're problem, then. guitars don't sound good through speakers like that.

in my experience, vintage speakers have suited me well in other applications, why not guitar?

thanks for the diagram truespin, but what is a speaker cup?
is that the jack?
#10
Yeah, the speaker cup is the jack. Should have a hot and cold lead on it.
I meant to say terminal cup.

Why would you use those small speakers? They won't sound good. Ditch the three smallest ones, and wire the two big ones in parallel to get a 4 ohm load at 80w. Or, just use the biggest one.
