Wiring options for 3 10" speakers

[pjd3]

Say, just curious on what you might do here.

If your baffle had room for 3 10's and you decided to go for it, and, in interest of matching impedances, would be inclined to say, A.) have two 16 ohm speakers in parallel with that parallel pair in series with a third 8 ohm version for a total of 16 ohms OR, B.) would you be more likely to say, have two 8 ohm speakers in series and then that series pair in parallel with a 16 ohm speaker for a total of 8 ohms? I have never actually played or experimented with different parallel/series configurations of wiring and listened for any difference so, I don't have any personal experience with sonic outcomes "if" there even is one.

I suppose in the interest of damage control having choice B.) above would make it so that if one of the speakers blew there would still be a load present to prevent any chance of flyback voltages. I'm personally not really worried about that as I never have my amps up very high, small to medium club rock band volume and clean pedal platform and miced.

Reason I inquire is that I like what I"m hearing about both the Alessandro 10's as well as the Fat Jimmy ceramic 10's. How people describe the Jimmy's might grab my attention just a tad more.

Have you tried different speaker wiring configurations with the same model of speakers?

Thats, would definitely be interested in your findings or comments.

The Fender Bandmaster 5E7 had 3 10" speakers. They were all 8Ω in parallel for 2.67Ω impedance.

Hey Sluckey,

I may have guessed that thats what they likely did back then. Originally, I was going to only put in a single 12" Weber C12NB and purposely made the combo cabinet very tall, around 27" just to have alot of wood. But then, I thought back to the two Super Reverbs and recalled how much I liked the sound of a collection of 10's. Unfortunately, the cab is just short of holding 4 10's or I'd do that but, I can get three 10's in there, alternated a bit.

The amplifier chassis (Priceton Reverb chassis) is already complete and has a mounted and wired nice Allen Amps 35 watt output transformer with an 8 and 4 ohm tap now that I think of it. So, I was not feeling very secure about having 3 eights in parallel into 4 ohms. I figured I'd see about playing some wiring games to land on one of the available taps.

Thanks,
Phil D

Hello—

Note well, 4 Ohms was a more than close enough approximation for the 5E7 Bandmaster.

I noticed some manufacturers are offering a 24 Ohm voice coil option. Handy for 3 or 6 speaker configurations.

Alternatively, use two 8 ohm speakers and one 16 ohm one. but watch the power rating

Thanks all for your insights into multiple speakers but I'm just going to put a couple of Fat Jimmy c1025's in parallel in this one. Keep the weight down and really that should be enough for what I'm used to doing. But back in the "loud days', playing through a Super Reverb was a pretty nice thing, and that many 10's didn't have me wishing for 12's.

Thank you,
Phil D
