I think most Klipsch and the MG 20.7/30.7 speakers are not that good. There is no low end in any of these speakers and the 30.7’s sounded so bad when we heard them on their intro tour.
I did have a friend that owned a pair of Klipschorn’s around 40 years ago and they sounded pretty good for their time, I think the wall helped in the lower end. I have heard knockoffs of these types of Klipsch speakers at audio shows and they were decent.
To get the more exotic materials for speakers, it’s going to cost you money. Your more cheaper speakers have drivers and cabinets made from cheaper materials. You will not get Porsche quality from a Corolla, price does matter for the better pieces
