Yes, I do. All of my speakers are set to small. Only God knows how many hundreds of hours I've spent tweaking.
If you have a DSP-based Axiom sub, set it to 40Hz and then set your pre-pro to 40Hz as well and see how you like it. One of the most memorable differences was the apartment shooting scene in LFODH. At 80Hz, the rat-tat-tats were thick, slow and rattled the whole house. At 40Hz, they were sharp, fast and we all felt them in the left butt cheek right through the leather couch.
And music's a completely different experience at 40Hz. The sub takes over right where the 80s leave off. Just make sure that you adjust the sub level to match the 80s at 40Hz (using a test tone CD). And if that doesn't sound quite right, don't be afraid to nudge the LFE channel gain up or down.
