I ordered a pair of Super Alnico Monitors last year. Sure, they took a little longer than he estimated but they were worth waiting for.
I attribute some of that time waiting was for the drivers which he told me he was waiting for, me taking a few weeks to pick veneer…. picking a veneer that was not a stock veneer.
He did a great job of book matching the veneer , it is striking actually.
I have always been from the camp that says speakers don’t take too long to break in. Not sure if it was placement, integration with sub or actual long break in but it took a while to really dial that system in.
