The speakers you are referring to are made by the person who used to make my cabinets and midhorns, so that's why you see such a similarity. If you don't have two good corners, you can build a three or four π loudspeaker with a midhorn. Just be sure the midhorn and woofer are within 2 feet of each other and the summing is good.
Do not attempt to undersize the midhorn, because it is pushing the limits anyway and requires boundary reinforcement, i.e. placement near a wall or corner. And I think I'd rather have a DI matched two-way than a three-way with crossover up in the vocal range, so I can't recommend shfting the woofer/mid crossover point up.
If you don't want to do a π cornerhorn, my best recommendation is a Profesional Series four π with the π midhorn, tweeter and crossover. You can load the woofer cabinet with a JBL 2226 or an Eminence Magnum 15HO. The Magnum can't be used up high, so it doesn't work in a DI matched two-way, but if you're making a three-way speaker with the midhorn, it will work just fine.
One last thing, you might have your wife look at the photo below. If you have two good corners, it would be a shame not to use them. They really look nice and seem to take up less room, so once your wife sees them, she will probably like them better than a freestanding speaker. It's hard to visualize the speaker from plans sometimes.
π cornerhorns provide uniform 90° radiation across the audio range which results in a balanced reverberent field. It makes a very natural sound, and is my personal favorite configuration. Next best thing is to put the four π's with midhorns in the corner, faced with 45° toe-in. It's not as closely coupled to the corner apex, but it's still pretty good. Next choice, for speakers that will be used in arbitrary locations in the room, I prefer the DI matched two-way approach.
If you're planning to put your speakers in corners anyway, you might reconsider this:
