Kazrog, have you ever tried a Warehouse Veteren 30? I'd be highly interested on your take of them.
Supposedly the "soft materials" are the same as what Celestion use/used in the English V 30's. The frames look a bit different, but to me out of the box they sounded more like what my older cabs V 30's sounded like over a minty new V30 in another cab I had. Not night and day, but surely not as harsh. I love Warehouse speakers. US made, cheaper, and sound better to me.
