I had two jl 113's running with Merlins and Sophias. I found the bass was much stronger when the speakers were in the limited mode. It was set up as a master slave.
I just got some andra II's and now I think its sounding better with the andras running full range, which surprised me.
Wehn i had the sophias running full range with the 2 113's it sounded very wimpy and my stereo installer was not impressed at all. When we changed it to limited it was a huge boost in bass.
It does take a lot of messing with settings to get things right, which is not my forte!
