Building a 2X15 guitar cab. help!

[darkesthour]

I have an old cab from like the 70s and i want to make a new cab for the speakers.

The cab contains 2 15inch 16ohm speakers. i was wondering how i could wire those together for 8 ohms.

I have a line 6 spider 3 head with two 8 ohm outputs on the back. could i wire 2 inputs with 1 speaker to each in the cab? or would this not work

I really am not to smart with wiring.

And I have never seen another 2X15 guitar cab :-( is there a reason for that? i love the lows of the 15s though!

Please help me out. thanks

Aesthetics. The footprint of the 4x12 cab is the standard so everything can be stacked. That's why you often see 4x10's and 1x15's made to the same dimensions as the 4x12. Of course, that's no reason to not build your cab exactly how you want it.

thanks for the help.

I was thinking about how dumb a 2X15 cab would look.

So maybe i could just buy two 10's or 12's and possibly build 2 different cabs with one 15 and one (10 or 12)

Or 1 cab with 2x15's and another cab with two 10's or 12's

just a suggestion though. As long as both cabs are wired for 8 ohms each it would work i think.

Let me know what u think about that>?

BE CAREFUL !!
If your amp is the Line 6 HD150, it has two outputs of 8 ohms minimum each, this amp is stereo and you can´t use only one of the inputs or connect them in parallel.
If this is the case, you can connect one 16 ohms speaker to each channel. The amp can handle speakers with more ohms but not with less. If your amp is the HD75 (like mine) you can connect the speakers in parallel to obtain 8 ohms because this amp is mono. Don´t worry to ask about.

Geez, maybe it's my age, but I would prefer the cab they're already in Why don't you just invest in new vinyl and grille cloth and restore that cab?

If he does this,will the amp will not produce as much power as it could into 8ohms?

Depends. On some Line 6's each output has it's own LM3886. If this is what he has then 1 driver per chip is the batter way to go.

But what I mean is ,should'nt an 8 ohm speaker sound louder(on volume setting 5 for example) than a 16 ohm on the same volume setting?
By the way do yous like my new avatar?

Well I have played out of this cab using only 1 output for about a year and had no problems.

Id really like to use the full power of my head though, so only using 1 output doesnt seem good.

And yea this cab is OLD! got it outa some old ladys basement for free so i cant complain. I really dont like the looks of the cab though, id much rather build a new 1 for it.

would 2 15's fit in a typical 4X12 size cab? Kinda like this.
