I have 2x D210XST 4-Ohm which I absolutely love.

I'm looking at getting some extra gear - specifically a 2nd-hand D118XL 8-Ohm, and thought I might get a D210XST 8-Ohm to pair it with, making a 4-Ohm load.  My favourite guitar shop is having a clearance special on D210XST 8-Ohm cabs.  :)

So my question is:  What's the difference between the 4-Ohm and 8-Ohm versions of the D210XST?  Do they just wire a 4-Ohm resistor in the 8-Ohm cabs and use the same speakers?  Or do the 8-Ohm cabs have different speakers to the 4-Ohm ones?  If the former, is there any reason I shouldn't just wire in a resistor and a switch into one of my existing D210XSTs?  If the latter, maybe I should take advantage of my guitar shop's hot offer while it lasts.
Yamaha RBX375, Kala U-Bass, Eden WTP900, 2x Eden D210XST(4 Ohm) .... yep, got that 2nd cab - and the pair is just beautiful!

Agreed, different ohmages, but I must confess I never really thought about it but what is the difference between a 70005 and a 70006?  Apparently identical in every respect except the ohmage! http://www.edenamps.com/accessories.html

The difference is the ohm ratings of the individual speakers they use in the cabs.  What speakers you use and how you wire them determines the ohm rating of the cab.  Remember if you wire in parallel, it will reduce the ohm load and if you wire in series it will raise the ohm load it by adding them together.

Your choices when using two speakers to make an 8 ohm cab is to either use two 16 ohm speakers and wire them in parallel (makes an 8 ohm load) or take two 4 ohm speakers and wire them in series (makes an 8 ohm load).  I believe Eden uses two 16 ohm speakers for that but not sure.  Armin can tell us when he drops by.

To make a 4 ohm cab virtually everyone uses two 8 ohm speakers and wires them in parallel, which drops the ohms load to 4 ohms.  Theoretically you could wire two 2 ohm speakers in series to get there too, but I'm not aware  of anyone making 2 ohm speakers.

To my knowledge, trying to use a resistor to change the ohms load doesn't work or everyone would be doing it.  You can't turn an 8 ohm cab into a 4 ohm cab by adding a resistor.  Armin can probably tell us why that doesn't work.  I just know it doesn't.  You physically have to put different ohm rated speakers in it to begin with.

Thanks Dan - but it still doesn't explain how two virtually identical speakers end up with different Ohmages - is it in the wiring?  The magnet maybe?  Could it be the cone?  I doubt that - but I'm fascinated...  You can have a speaker reconed etc - can that also change the ohmage???

Hey Paul, I think it's mostly down to the diameter, amount and composition of the thin wire that makes up the voice coil.  Reconing replaces the voice coil so it is possible to change the ohms when a speaker is reconed.

In that case I'd expect the weight to be different... interesting...

Voice coils weigh very little--they have to move back and forth in the magnetic gap at thousands of repetitions per second.  Not much mass there regardless of ohms.

Bob is correct.
Paul, the 8 Ohm coil would be heavier than the 4 Ohm, but the diameter is lower of the wire, therefore the coils weigh more or less the same.

This is a good topic. But let me ask the following, in a two speaker  8 ohm cab, depending how it is wired, parallel or series, the speakers  could be either 4 ohm or 16? If so, which is preferred?

Correct, and it doesn’t matter.
If I really had the choice I would take the 16ohm cab.
Because of the parallel wiring the cab can stay operational if one woofer dies.
But how how often does that really happen.

And with 16ohm cabs you can run a lot of them all at once!

But he was talking about woofers not cabs.
The cab impedance is 8 Ohm in both cases.

Could a different ohm cabinet be used with a different ohm head, or must they match (4 ohm with 4 ohm)?
