I understand. The Betas are pretty good drivers. I used to use them but felt there was too much overlap in my product lines so I dropped them. As I recall, the Beta 15 would work pretty well in a Theater Series four π cabinet and your analysis tends to confirm this as well.
If you want a great bang for the buck, pick up an Alpha 10 and put it in a 4-5ft3 box tuned to 35Hz. I expect you can get those even cheaper from the dealer near you. They're a great part - can be used for a midrange or a woofer.
