What did I do??

Now that you’ve explained the back story I think you will be thrilled with Moabs. Big space to fill with mid level tube power means the larger box with more cone area will deliver big improvements in bass slam and overall sonic impact. Your early formative ownership of L100s tells me that you are conditioned to prefer a more dynamic presentation. But by my reading Moabs also possess considerable subtlety to go with their sheer impact. So they may be your perfect solution.
