Wondering if T/S data is availabel for Altec 416? This is one of a hand full of drivers that performed very well in a Karlson K15 cabinet. Am also wondering what modern driver might come close to the 416 in sound quality? No insult intended here but used and rebuilt Altecs cost a bundle. I would like to believe that with the world of experience someone builds a driver that sounds like this one? Any suggestions/comments? Best regards Moray James.
