Anyway to wire 3 - 8ohm speaker to get an 8 ohm load? series/parallel ?

I dont think so...I think if you had two 4's and an 8 you could get there, but not with three 8's.

I know a lot of Output Transformers are supposed to be able to handle Resistance in either direction, I've always thought that a 3 speaker deal, being some odd number of ohms, was a little shakey. 4x10's are so cool anyway! Mark

yeah the old "Bandmasters" were wired for 2ohm..Vibro Kings too!...4X10 hmmm

I would shoot Ted Weber an email and ask. I would like to know the answer to this question.

Anyway to wire 3 - 8ohm speaker to get an 8 ohm load? series/parallel ? In a word, no. If you put two of them in parallel, and hook the third in series to those, you get 12 ohms. If you wire two in series and put the third in parallel, you get 5.3 ohms. All three in parallel is 2.7 ohms. All three in series is 24 ohms. There just isn't any way to get to 8 ohms with three 8 ohm speakers.

Got an email from the DR he said he uses 3-16ohm speakers wired in papallel for a 4 ohm load ... So I'll tell my brother that's the way he should go... thanks everyone for the help!

Well three 16 ohm speakers in parallel is 5.3 ohms, but that's probably close enough. Keep in mind that we're talking about impedance, which is not really the same thing as resistance (the ohms law formulas I've been using are based on resistance), and generally speaker impedance is only measured at one frequency (typically 1KHz) so there is a lot of leeway and fudge factor. So if you can keep track of that run-on sentence, you know you're probably ok if the doc says so...
