If it were me, I'd eat the losses and go with a different driver. Staying in the cheap, I'd go with the Infinity Reference 1260W/1262W. I picked up a pair last year on Amazon for $50 or so each. They are pretty comparable to the 12" Infinity Kappas. Even if you have to build a new box, you'd still be ahead assuming they don't budge on the price. Without looking at the specs on the 10" Kappas you may even be getting better performance down low by going to a pair of 12" drivers. Another option for $200 is to go with a single 15"/18" driver like Dayton or SI. You still need to by MDF to build a new box though. To me spend money on 10" drivers for HT is a bad investment unless there is a specific requirement for them.
