If I remember rightly you don't gig? And have no plans to? I'm going to have to be brutal, and coming from me this may be seen as the pot calling the kettle black, but....
What a complete and utter waste of money
:)
Ok, here is the rationale...
I have 2 heads, I'm intending to keep both of them. Therefore I need 2 cabs if both myself and Sue want to play together.
The Diezel cabs are 8Ohm where the Orange cab is 16 Ohm which means I don't have the full stack option even though I have 2 cabs.
One cab will be going, I'm not keeping all 3, but until I've A/B/C'd them all I don't know which, but the Orange is the most likely for the afore mentioned full stack option.
Sale of other gear plus the Orange will cover most of the cost of the 2nd Diezel cab, so for not much extra cost I have a flexible rig of 2 half stacks or a full stack, with complementary drivers in each cab. Or I can return 1 Diezel for just the cost of shipping it back.
I know that still won't make sense to everyone, but there is some logic there (somewhere).
