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). |
The above doesn’t include down-firing woofers, such as might be found in a Leslie, or subwoofer system. I have seen those sag.Front firing,the top of the bass driver sags/leans forward and causes polling, Kef B139’s were known for it, so were my Kef B1814 bass driver and also I believe Lowther drivers had very tight magnet/coil gap and needed to be rotated every now and again. YEP: another 20 yo zombie-thread (as Ralph calls them), resurrected by someone with nothing better to do.At least back then there were a lot less snake oil fuse and hrt etc etc voodoo threads Burn in for speaker suspension pliability/compliance is a real thing Cheers George |
