That Feastrex driver by all accounts is sweet, if not expensive.
Funny how all history repeats itself. 50 years ago console stereos consisted of extended range drivers mounted in an open baffle (the back/bottom of the cabinets were open). Americans never did "get" the stereo concept, and unfortunately neither did those who mix most recordings, so the market quickly bought into the bigger is better mantra. Now with the resurgence of dipole designs the mantra returns, perhaps due to a reaction to use of headphones/earbuds (which again there is precious little music mixed for them).
