It seems like everyone including myself are always searching for the plus or minus 3DB flat holy grail response but in that flat response I feel as though I’m missing that chest thumping bass when I play certain types of music. Do you guys ever cut your super low frequencies and boost the mid base on order to get that thump or do your systems give you that chest thumb even with a flat response?

Not missing anythingng particularly so no I don't do that as mostly its more a matter of spl so I'll just simply turn it up. Some do add mbms (mid bass modules) chasing that sort of thing, tho. Depending on the equalization you might apply, you could customize a curve more to your liking. What frequency range are you concentrating on? What's your rig?

I’ve got that ridiculously stupid 18 inch ultra max dipole set up. Nice flat even response but missing that chest pounding thud.

I think I’m looking for that 60 to 85 Hz boost.

Could be a XO integration issue. Can you post your sweeps? The camera icon in rew saves a jpeg that’s easy to post.

On large organs the 32 ft stop can make my internal organs vibrate without altering the calibration. I don't change anything by source or genre.

Agreed.

I get the same rumbles with my setup. I'm looking for chest thud during kick drums and such. Going to run rew real quick and take snapshot.

That chest thump you desire likely extends above that. And if you try and achieve it by only adjusting sub levels it will mess with integration of the sub with the mains. You should be able to apply global eq once your subs and mains are dialed in. Try running a tad hot up to 120-150 Hz.

Looks like that region needs a lot of help. Might need to get another minidsp and external amp to fix this mess above 100hz.

Fortes are already pretty robust from 80-120 or so, and have gobs of dynamic range to offer. You should be able to achieve what you want with them.

You can definitely run the fortes as large/full range. You might try that, using the sub only for the lowest octave, low passed in the neighborhood of 40-50 Hz. Maybe, possibly, running the sub to higher frequencies is causing some issues.

Try a +5 to the sub channel. Listen and see, and measure that. The graphs could be better but aren’t horrible. Looks like a house curve is in order but a bump would be a good start. Flat is just that...flat.

I think it might honestly just come down to the sub enclosure that everyone on here has been telling me to toss in the garbage. Just waiting until I can purchase a couple of sealed flat packs from parts express or diyaudio to build. Then I can put these two ultimax 18's in a proper box and get the SPL I think I'm after. At lower volume levels it's just bliss, but when I want to crank these bad boys, I just don't have enough SPL with the subs. They are not efficient at all in their current setup. I have to believe that 1200 watts going into two ultimax 18's should give me more than I need in a proper enclosure.
 
QFT, especially if the OP increases the volume to achieve the chest hit, without rolling off the highs he may rip his ears off.(Seriously, though, while they need some massaging to be their best, the fortes are some of the best of the classic Klipsch.)
I had Klipsch RF 82 II's before the Forte's. They had much more thump but they hurt so bad when I turned them up. The Forte's roll off much sooner and are much more gentle on the ear drums.
 
RF82 < forte, IMO, not close, particularly in the bass. Forte bass is tight, dry and resolving, not bloated or ringy. Fortes are better in the midrange as well. Having a single driver covering 600-6000 Hz means no passive crossovers molesting the speech discrimination band.

By design the fortes rely on boundary reinforcement to dig deep (f3 is in the low thirties, but only if stuffed deep into corners), but since you have a sub for that your priority should be for positioning catering to imaging. Due to their high directivity down to low midrange frequencies, fortes lend themselves to extreme toe-in orientation to take advantage of time/intensity trading. That will dramatically expand the sweet spot. Google up the Bill Waslo authored paper on the topic.

The rest of my forte tips relate to eq, and I'm not sure what eq capability your kit provides. If possible, play with reductions of 2-4 db in the 2-3kHz area. That will really take the edge off and deepen the soundstage.

And use caution in search of chest thumping bass. Your rig is capable of serious spls. Listening at safer levels may demand some loudness eq to get the same effect, but you won't end up with tinnitus.
