Re: Introducing the Sierra-LX!!!
I found a measurement. I will try to load it.

Assume you've also used REW to generate correction frequencies to apply in the miniDSP in the attached plot? Should be easily able to flatten the response from 80 hz and below.

What receiver are you using?
Re: Introducing the Sierra-LX!!!
My speakers front baffle are 22" from the wall.
Dave the measurements are the LX's and subs crossed over at 80 and 150 Hz. Taken from the MLP.
I am pretty sure that these were taken when connected to my Anthem MRX 720.
I did use REW to flatten the subs for both measurements. The only thing that changed was the crossover.

Re: Introducing the Sierra-LX!!!
This is a measurement comparing the LX's to the sierra 2's. No subs and no REQ.

As you can see the LX's put out so much bass that doing a sound comparison between the two speakers was almost impossible. I always preferred the sierra 2"s without the subs. When crossed over to the subs they sound very similar.

What are you using to take these measurements and where is your microphone placed? Something is definitely not right... yes, the LX do have more bass than the Sierra-2, but the differences should be about 3-4 dB at 80Hz.... Your measurements are showing a massive difference of nearly 16dB! That's simply not possible.
Did you use EQ with the Sierra-2 and then leave that same EQ in place with the LX? If so, turn that EQ off with the LX.
I'd recommend taking the MiniDSP out of the system for now

The measurements were taken with a UMIK-1 placed at ear height in the MLP.
I do not use any room eq at all. This is just the front speakers.
I removed the wires from the sierra 2's and put the LX's in their place without moving the mike.
The MiniDSP is used to time aline the 4 subs with each other. I then check different crossovers to get the best blend between the subs and the speakers. In my room this is always in the range of 150 Hz.

I think you should use some form of room correction on the low end of the speakers. I have the same issues. My Sierra-2’s are somewhat corner loaded and sound really boomy without room correction. Once you tame the low end with room correction, you can cross over lower with the subs without it sounding boomy.
