F-Mod Installation Direction
Written By Joseph, Albuquerque, NM on Monday, July 27, 2009

I have used dozens of F-Mod audio crossovers for decades. They work flawlessly, but only if they are installed in the correct direction. They do not come with installation instructions. I have seen many F-Mods installed by other people that were in backwards; in fact about half of those were in incorrectly. Harrison Laboratory should include a small diagram showing the proper direction of installation. The F-Mod male plug goes into the female connection on the amplifier, not into the female connection on the preamplifier.

Unconventional use
Written By John, Chicago on Tuesday, May 08, 2007

I used one of these to convert an old spare subwoofer into a mid-bass enhancement speaker for my home theater. Works great. Maybe not equal to a $500 mid-bass module especially designed for this use, but close enough and only a fraction of the cost.
