Since I'm grateful to Ed and Steve F for their "The great Heil AMT is on sale" posts, I thought I'd (hopefully) return the favor to anyone powering Ed's FFRS subs.
Crown is offering $50 off their XLS amplifiers through February 28, 2019
https://www.crownaudio.com/en/promotions/more-power-for-your-pa in the US only.
Just an FYI for those who might be interested.
Update: Could this be "bait and switch"? The link above shows, say, the XLS 2502 for $550 (list @ $600) but as an experiment I added it to my cart, and the price shows $600, but a
new list price of $650! I'd suggest a phone call to them if someone's considering a purchase.
