I have several sets of Chinese Quads. Fit and finish is good, not German, but good. Components are average, beginning to fail at 15 years. Just in case you are still interested.
Not manufactured any more.
I'm looking at old Pics of speakers that I would love to see come back.
I'll post two or three. What do you like? Post your DIY or that speaker that got away..
Enjoy the Holidays
