Don't need LPF on subwoofers?

[olds1959special]

I am experimenting with running my subs full-range again, and cutting bass using EQ to deal with room modes or using the low trim and HPF on the speakers. I like running the subs full-range for some reason, or as high as the LPF setting will allow.

I guess subwoofers aren't optimized for higher frequencies but I don't want to limit the subs frequency range. I would rather cut bass in other ways.

Subs and mains have different decays. You should trim the sub or the main, but I wouldn’t recommend letting both without any crossover cut. Depending on the location of the sub, because >100Hz frequencies are directional, if you only have 1 sub located on one side or behind you, the sound spread in the room would be affected.

Yes, I'm saying trim the main instead of the sub whenever possible, or play both full range and EQ as needed to deal with room modes.

This worked when I reduced bass with EQ and my subs are limited at 130 and 90Hz but in my other system I had to go back to using crossovers.
