Vintage Mirage speakers circa 1980 that FAR EXCEEDED my expecations! Mirage SM-.5

I am in process of restoring these Mirage speakers I stumbled across. Replaced the Rotted Foa surrounds, redid the grill cloth. Checked what little crossover components there was, no joke like 4 parts. I had Low expectations as Ive heard lots of Box speakers of this era. WELL NOT THESE! n was floored by the Imaging, the spaciousness detail retrieval and just the Natural Timbre of these. Mirage had a trick or two or some wizards working for them and these are some brilliant unassuming speakers!
