Anyone Ever Try a 3-Speaker cab?

Anyone here ever try taking an 8ohm speaker in series with two 16ohm speakers in parallel or something of that nature?
 
Re: Anyone Ever Try a 3-Speaker cab?

It won't split the power equally to the speakers.


*EDIT* - To clarify, in that arrangement the 8 ohm speaker would get 50% of the power and the 16 ohm speakers would get 25% each.

If you made an 8 ohm load with a 16 ohm speaker in parallel with 2 8 ohm speakers in series, the 16 ohm speaker would get 50% of the power and the 8 ohm speakers would get 25% each.

I figured that, but I was wondering if anyone had found a way to make it work, I can think of several ways off the top of my head, but don't know If the idea would be worth the trouble.

I'd be interested to hear your ideas, twisting the laws of physics isn't for the faint of heart.

Without getting into clever circuit design, you could always experiment using higher sensitivity speakers on the side with lower wattage. Or differently voiced speakers may also stand out from each other in interesting ways. Depending on what you want from it, you may get good results.

it might work if you put the 2 8 Ohm speakers in a cabinet that was @-270 degrees C...

That's what I was thinking. A quiet scooped speaker with two loud middy speaker.

Well, both those speakers still get total of 50% so I don't think it matters. Why should speakers get equal power in the first place?

I'd be really interested to hear about this. In fact I had planned to try it myself when I got my 2x12 ready (I currently have 1x12 with 8 ohm speaker and two 16 ohms for the project cab).
 
Re: Anyone Ever Try a 3-Speaker cab?

Sorry, I thought you meant a way to get equal power to the speakers.

Sounds like a lot of trouble, at this point you might as well just get a 4-12, it's not like you are saving a lot of weight or space with 3 speakers vs 4. Of course, this is just my opinion (and apparently 99% of amp/cabinet manufacturers).
 
Re: Anyone Ever Try a 3-Speaker cab?

think a cab with 2 X 10s @16 plus 1 X 12 @ 8 would be greeat....get the response and sparkle of the 10s plus the full low end from the 12...still have to super cool the pair of 10s...maybe....
 
Re: Anyone Ever Try a 3-Speaker cab?

If it is something you really want to do, the easiest way would just be to put 3X 16 ohm speakers in parallel for 5.3 ohms and set your amp to 4 ohms. All the speakers would get equal power and it won't hurt the amp.

It's good notion with the power distribution :) Just wanted to note it's not necessary always. Maybe not even desirable in some case.

I thought about it more out of curiosity rather than any practical use.

I think something like couple 8" with 12" speaker might yield interesting results. I really wanted to try that out when I had those Eminence eights, but impedances didn't work out.

One reason I opted for 16 ohms last time I was buying speakers. Much easier to match.

Two 16 ohms + 8 ohm. ;)

Since 16 ohm speakers are the same, that should be perfectly balanced
 
Re: Anyone Ever Try a 3-Speaker cab?

Nope, can't split equal with different impedances, it's that darn physics thing again/still. I actually answered this in my first post.
 
Re: Anyone Ever Try a 3-Speaker cab?

Assuming that the sensitivity of all 3 speakers are the same and the 16 ohm speakers are paralleled, I'm still not so sure that the 8 ohm speaker would, necessarily, dominate the mix. Each 16 ohm speaker will get half the power of the single 8 ohm speaker. But, the 16 ohm speakers combined will get the same power as the single 8 ohm speaker and you do have double the cone area assuming all 3 are the same size. It may not do what you want, or expect, but I don't see why it wont "work". Only thing I have done that is close is 3 subwoofers in a car audio system. I think they were all in their own air space and they were all the same drivers with the same impedances. That's an apples to oranges comparison anyway.

Maybe 2×12 @ 16 and 1×12 @ 8 would match better volume-wise with the right set of speakers.

AIt may not do what you want, or expect, but I don't see why it wont "work".

It will work fine assuming the speakers are size appropriately for the power, I didn't say it wouldn't work, it just won't split the power equally.

Maybe 2×12 @ 16 and 1×12 @ 8 would match better volume-wise with the right set of speakers.

That is going to make the mismatch worse, now you have 2/3 of the power going through the 8 ohm side and 1/3 getting split equally through the 2 speakers on the 16 ohm side (2X 8 ohm speakers in series?).


FWIW, yes Fender did make a 3 speaker combo, can't remember what it was now though. I did play through one years ago and remember it sounded awesome.

Tweed / Brown Bandmaster IIRC. I've played one as well, and it's a cool amp.
 
Re: Anyone Ever Try a 3-Speaker cab?

Cool, thanks, the one I played through would have been a reissue in the mid nineties-ish timeframe.
