I have been doing alot of reading latley about when to X-over to the sub and I am just curious what you guys are using?

I'll have to double check when I get home but I am pretty sure I am at the standard 80. I know the speaker will go down further than this but "some people say" that by crossing it higher you take a load off the speaker and it will sound better?

Doesnt really make sense to me but I'm pretty new to all this and just trying to learn.

I have M60s and an HSU VTF-2. Everything is set to small.
