The LF's sensitivity is lower than the TC, so, if you use just one, you will have to bring the TC down a bit.
Here's a quick sim of the two drivers.
You can start without the BSC (L3 and R1) at first.
If you feel the driver is too bright, you can add it later.

Thank you KaffiMann for reposting. mauri99, you are too kind, in that what I have done is similar to the efforts of other members. Keep it simple. Measure the drivers before you cut holes in the plywood. My drivers are 385mm not the 381mm listed on the spec sheet. Set up a crossover and listen, it takes quite a while for the drivers to break in. Then you need a measuring microphone and use REW, seems to be the most popular choice in software, and it's measure, adjust, measure, adjust till you like the result. Obviously, easier done in the digital domain. I put small wheels on the speakers as you will be moving them around to adjust the sound in your room. Sit back and enjoy.
Stlll liking the FC152's?
I found that just notching some resonant peaks sort of relaxed a lot of the sound over a wide range, then it was just padding down gently a tiny little bit with a downwards slope up in frequency. Not much needed. Noticed there where some peaks that where visible on several listening positions, went for 8 point measurement overlayed to see the peaks in question.
May be somewhat dependent on implementation.

mauri99, I'm very satisfied with the results. Full bodied, natural vocals, strong mid-bass are some words that come to mind. I have screwed 8-10 cm wide strips on the back side near the baffle edge as much to hide the drivers from view as to bolster the bass. I have used speakOn professional connectors since they are cheap, lock in place and were ordered in different colours so I don't confuse which wire is for the full range or bass driver.
@jazzfan: Very interesting! I had the same concept on my mind, just not found the time to build it. I'm currently running two Fane 12-250 TC in a baffle with some rear damping and quite some EQ (the most fun way to break them in
), but planned to extend this just as yours. However, I'd like to run the drivers passively, with the future option of active EQ if bass extension isn't enough.
Could you share your settings on the miniDSP?
Also, what's your experience finding the crossover point?
The measurements attached are in the test baffle, h115xb50, with rear damping by thick carpet, no EQ, 6ms window, 15 deg. steps 0-15-30...180 degrees. Not calibrated!
Note the lack of strong peaks in the power response (middle, dark blue)

I'm looking for a good speaker to test all my amplifiers.

Hello Thimios, I do not have that setup myself, I am using the now discontinued Fane 15-400 for bass, 2 per channel in ca 120 liter vented box per bass driver, and my beloved FC152 are in ca 80 liter sealed. Here is a picture anyway.
Will be several more days before I can hear them again
Looking forward to firing up the system maybe on saturday.

I'm getting the sense that the 12" benefits from a supporting woofer whereas the 15" can stand alone, depending on implementation details.
I'm still thinking to use this speaker for a keyboard amplifier/portable PA
Problem is I can't really choose between the 15" or 12".
I think the 15 can give more bass but the enclosure will need to be bigger....
Also would be nice to get "stereo" from one box so I was thinking to angle the baffle. Not ideal but it's portable....
