So I was looking up cabinets on craigslist. Basically Ampeg has a lot of 4x10 and 8x10's with really similar names so I always have to go look them up on their site to get the straight dope. Well I came across this little bit of trivia. If I am to believe the Ampeg site, all of their cabs (with a couple exceptions) are 98db sensitivity. So the 4x10 is just as loud as the 8x10. The 6x10 is as loud as a 1x15 and so on. Is this an actual fact? Does ampeg get the drivers custom made so that all of their cabs are the same sensitivty, allowing you to mix and match cabs for tone, not volume? Or is someone at Ampeg/Loud very lazy when putting together the specs pages on the website?
