Bought a new digital cheapo multimeter and tested a few "known" speakers.The meter was reading bang on for ohms.
1)Tested 2 older 8" Jensons in my National tube amp..they are in series...and I was getting 2.3 ohm each...can I assume that these are 4 ohm speakers or is the series wiring and the proximity to the OT affecting the reading? (didn't want to unsolder just to do test)
2)am (slowly) working on a 4X12 cab with 2X12 4ohms (8 ohm load) in parrallel and 2 single 12 8ohms individually wired. Is it possible to take a 1/4" jack "Y" short speaker cord and plug into both singles to get a 2X12 4ohm load?
3)best recommendation for an 8" bass speaker for a 40W ss Traynor? (I know...8"bass...WTF)
any and all info greatly appreciated. Its getting too cold to mess in the shop, so back to the kitchen table workshop...LOL
cheers

To start with you can't measure the DC resistance of speakers that are wired into a cabinet.You will get the working resistance of the pair wired in series.
The DC resistance is close to the impedance.For your 2.3 ohm reading,that is close to 4 ohms,so that's correct.
Two 8 ohm speakers wired parallel gives you 4 ohms and two 8 ohm speakers wired series gives you 16 ohms.
There is no change in readings being close to the OT.
