Buy this and just play the ’Pink Noise" track over and over, be careful of the others, they "can" damage your amp/speakers

Hope after 20 years those speakers are burned in!

He might have new drivers to break in.
As they get problems when old, the magnet/coil gap has very little clearance and can scrap/pole after a while if the drivers are not rotated 180 degrees every couple of years to counter the sag.

I bought a $69.00 CD/DVD player and this disc, specifically for burning in things: https://www.amazon.com/Cardas-Acoustics-Irrational-Efficacious-Burn/dp/B00OY8UXME       The disc has Pink, Brown and White Noise tracks, that can be played on Repeat.      They do a great job.      There are six Seimens CCAs, that I don’t want to unnecessarily wear, in my system CDP (thus- the cheapo player).                                                 In the decades that I professionally reconed speakers (as a warranty center for EV, Altec, JBL, Cerwin-Vega, Gollehon, Cetec-Gauss and a Waldom reconing center, in Orlando, FL), I never had a repair come in, do to a sagging suspension (unless they’d gotten soaked in something).
