I just want to point out that Wilson was making very different speakers in a different market then than now.
Not that I’m a fanboy or could even really justify their prices, but when we look back at vintage speakers we are looking back at different times and tastes.
Vintage Infinity, Focal and B&W all can easily be criticized by a DIYer/modder. Troels Gravesen has also done a few rebuilds (Yamaha, Snell) but sticks more to the facts.
While it's easy to critique these vintage pieces now, it's also good to remember that they were actually what was considered successful.
I’m not saying don’t mod, but be gentle on the reputations of the original designers.
