I find myself asking why so freaking long to finally want a pair of altec 19. Ever since covid I had a chance to slow down and spend more time exploring the tube audio sound. The more I got into it the more I kept hearing about the sound of the altec 19. Which brings me here. So like I need another pair of speakers. So here I go I want to have a pair custom build 19. Where should I go to find decent drivers . What should I stay away from. I have a guy who is going to build the cabs for me. Anyone knows of xover upgrades. Thanks
