Given that the LSi15s apply a 150 Hz high pass on the 5.25" and your amp should be up to the challenge of driving the woofer in the LSi15s, setting the crossover will be more of a personal preference. It will depend a lot on speaker and sub placement.
I was a bit harsh and I apologize for that.
One thing you have to realize is that you will NEVER get the kind of sound levels out of a bookshelf speaker that you will out of the monster speakers they use in movie theaters.
This is obvious and I know you know this.
That crossover point is too low for LSi9s in a home theater environment.
For music, that's fine because music dynamics are much smoother and forgiving than home theater dynamics.
The key is that even with the crossover set to 40, that's just the point at which the crossover is going to start rolling off the signal to those speakers. They will still be playing below that at an attenuated level so with massive spikes in volume, even with the db level decreasing the farther out from the crossover point, you still risk hitting spikes that can and will cause damage.
NEVER trust your auto calibration.
Use it as a baseline and work from there.
Granted, it is mostly going to be what sounds good to you but there is a reason subs are designed to handle frequencies from 20hz to 120/140hz.
@ jhyman: Did you even read the thread? The OP has already admitted todriving the speakers beyond reference volume.
And the OP cooked 2 drivers while running a too low crossover point for home theater dynamics.
The post you are linking doesn't make any reference to going above reference levels and had damage to the crossovers not the drivers themselves.
If you loathe this place so much wtf do you keep coming back? Nobody wants to hear what you have to say here anyway.

Once that is done, manually run the test tone and check the output from the speakers with an SPL meter. They should all be equal.
Like I stated previously, auto calibrations are notoriously inaccurate.
If your listening position is centered in front of your TV and your speakers are equi-distant from the centerline, they should be pretty close to the same db level and distance.
Same goes for pretty much the rest of the system.
One of the things I would also check is how far your subwoofer is reported from your listening position. I am willing to bet that it isn't even close to the actual distance.

Jesus what did I do now, YES I did read the thread and so what only the Tweeters can have an issue not the woofers or vise-versa, even the OP read that thread and said he wondered if the speakers have a flaw..
I all depends on how hard it was driven in the first place..YOU were not there..
and I guess I was the only one who that, NOT..
THIS post is about LSi9s and a single blown top woofer in each. No known damage to crossovers with the OP stating that he turned it up well above reference.
The post you linked is about RTi7s and blown capacitors in the crossovers of each speaker. No drivers were damaged and the OP in that thread never mentioned excessive volumes. Only that he "turned it up a bit" and suddenly everything went quiet.
What we know:
LSi9s and RTi7s do NOT use the same crossover networks. They may share a capacitor or two but other than that, they are complete different crossovers.
Damage in both threads are to completely different components and the listening in each, completely different.
Now, I will relent and say that *if* both threads were about the same speakers that used the same drivers and crossovers, you would have a case.
But they aren't, they don't and you don't.
And my information is based on the information provided by both posters. So unless they are both deliberately misleading all of us, my advice and comments stand.
That being said, i set the crossover to 80 hz on all speakers INCLUDING the subwoofer which was set at 120 hz. Should i leave the subwoofer at 120hz or drop it down to 80 hz like the rest of the speakers?
