Sealed, BR..which way to go..

I've been trying my LM755As fullrange drivers in Swissonor B.A.C.H.8e cabs, both br and sealed mode. Please, don't ask how did I proceed that, but I did anyway..;) I think I've got the answers and I have a strong feeling, that building br cabs is for me to way to go and get the most out of the 755As. Those are real great drivers and I think to get them really sing and real fullrange use is to build big enough cabs, perhaps like these..
