I had Forte IIs for ten years, what seems like a long time ago now. Rebuilt my own crossovers with some paper in oil caps, purchased a bunch of upgraded resisters to dial in close tolerances. Added vibration damping to the backs of the horns. After all that, it wasn't much if any different than stock. Probably because I put in upgraded replacement parts with stock values. My advice, buy the ALKs. You can always put updated parts in the stock crossovers to refresh them which would be more similar to the Crites and stock versions.
