I am a new member to this forum (was directed here by Martin Logan office) and have a couple questions.

I'm the original owner of a pair of Martin Logan Monoliths that I purchased over 30 years ago. They are still running strong! Not sure if they are series I or II. I think they are II's. Definitely not III's.

Recently I moved and have a couple questions.

I have a high-end Velodyne servo subwoofer connected to the system. I have forgotten the high-pass frequency setting I should use on the subwoofer.

Also, I don't know the impedance of the speakers themselves (new amplifier and need to set impedance properly).

Can anyone help?

Thanks much!
