I have had a Definitive Technology system for years and the dipole are great for the surrounds let alone the BP2000 front towers.
3 years ago they built a new Marcus theater 2 miles from where I live and the Dolby Atmos is so good. Then it hit me, that if I was going to upgrade at home my surrounds would have to go - object based sound needs a narrow field.
Dipole speakers are great in 5.1 and 7.2 systems so there still will be a demand for those individuals that can cut holes in their ceiling.
After 15 years I just shifted to a new speaker system with no dipole rears. If I could only sell my top of the line Def Tech. (:-<)
