I have just bought an MJ Acoustics ref 100, and am experimenting with the set-up. I was wondering if anyone with a similar sub could answer the following: 1. Is there any run in procedure that should be followed? 2. MJAs website recommends using the low level input to take the LFE feed from an AV amp, whilst using the high level input to add bass to the centre channel at the same time - has anybody tried this?
