Hey guys I am flirting with trading in my Ampeg on the Aguilar but not sure yet. I havent had a chance to play on an Aguilar at all yet so Im not sure of their sonic properties/characteristics. For those that have played the Ampeg SVT-410HLF like mine how do they differ. I was told that the Aguilar will be louder because of the higher efficiency (even though it is 2 less speakers). What about lows, mids, high's, etc? Oh just as an FYI as well the amp is a QSC 1850HD and the preamp is a BBE BMax.
