I bought real vintage speakers from the nineties, they are still powerful and have a great sound. Unfortunately I had to replace my PA with two fat PAs to provide enough current. :

Picked up a pair of Infinity Kappa 9.2 together with a NAD T753 last week. The amp is way to weak to handle these beasts but their in good condition, just need to clean them up some more. : r/audiophile
