hi steven
yes the EVM was very much a sterile speaker when new (and very bright), and it has taken literally months for it settle after being installed. i have noticed in recent weeks that the midrange has started to change as it breaks in...and take on some character. but as i said before.... it still sounds great as you turn it up and does not turn to mud like the g12-65. i use the two together for must stuff and they work well together, however the EVM sounds prominent
the amp gets a hard workout for 4 to 6 hours every week with band practice... and then another workout with gigs as they come up.... i guess it will keep improving with time.....
