Mismatched cone dilemma in my Eden D210XLT

Well, I have a D210XLT reading 8 ohms on the back of the cab. I blew a cone on tour and in a hurry bought a pair of EC1060F speakers on the road. I assumed they were either 4 or 8 ohm, but realized when i had my flashlight and screwdriver out in the parking lot before a gig that they read "16 ohm" on the back of the magnet. What to do now?

Obviously the cab is wired in series, with two 4 ohm speakers combining to total the load at 8 ohms for the cab. I sure as hell don't want to end up with a 32 ohm cab, but I had no choice but to put one 16 ohm speaker in alongside the remaining 4 ohm speaker, to help protect the original speaker from blowing while taking the noisy one out of the chain. The show must go on...

What the hell do I do now with a 4 ohm speaker and 2 16 ohm speakers? Can I rewire the harness in parrallel? I couldn't find any Eden literature detailing this process. What would that leave me with, a 12 ohm cab or something? Am I in danger of blowing my head now too? Any advice is appreciated. I'm good at most things audio; cab impedance being the last of them.

My plan right now is to carefully run the cab with the original 4 ohm speaker and the new 16 ohm speaker until I can get a replacement speaker. I unfortunately just sold my backup and quickly squandered the funds.

I have a WT 550 head, if that helps. Also, on a related note, if anybody wants to sell a 4 ohm EC1060XL speaker let me know.

welp, i figured out the math right after i posted this... classic newb mistake.

i guess what i should have asked is... does anybody know how to switch from series to parallel with the wiring harness provided in the eden cabs?

Parallel connection: Take the two incoming wires to one speaker - call that the first speaker. Run jumpers from each terminal of the first speaker to the matching terminals of the second speaker.

You should already have one speaker-to-speaker jumper wire... you'll probably have to make a second one.

But if the original wiring is in series, that jumper will be from the + terminal on one speaker, to the - terminal on the other. You'll need to change that. connect all positives together, and all negatives together.
Here's a diagram...

Yes, which is why I said "Run jumpers from each terminal of the first speaker to the matching terminals of the second speaker".

The second paragraph was to let the OP know he'll need another wire. But I take your point, which is that the existing jumper must be moved.
