I wouldn't even go there without a cheque from wifey for $10K (6K for new speakers and another 4K for mistakes you might make in your search). Providing you with the cheque doesn't give her any input on the choice either since it was her idea, not yours.
Maybe after seeing your "bill" she will learn to live with them or suggest putting them behind acoustically transparent curtains (which you could open for critical listening).
