My Sound level meter arrived yesterday and tried it out tonight. After calibrating it, all bass set very low to start with, some bass settings turned off, I got a reading of;
I`m only running a single 15" Kicker sub and R/Fosgate Amp. But when turned up slighty, it kicks. A well matched amp and sub helped though.
Will be trying it again soon but with the Punch Bass device connected and bass settings turned up more. Should be good.
I might bring it along to PV04 on Sunday if anyone`s interested.
