Bridging doubles voltage output, so power quadruples. The NC122 would bridge to 120W into 16, which makes sense because each channel would see half the total impedance. IOW, the bridged output at 16 is the sum of the stereo outputs at 8.
Actually, you are correct. My previous statement of only doubling the power was based on the Fusion Amp manual, which says that the power is only doubled (probably current / power supply limited). But in fact the NC122MP specsheet states that it can BTL 250 W @ 8 Ohm load (only 200 W @ 4 Ohms). If we are operating with 16 Ohm load, we can assume it can supply full power to that as well. Thanks for pointing it out. Hooray for BTL!
Hello Audio Friends 
There is my little PA System I use for indoor and outdoor electronic music reproduction.
It's a fully active driven 4 way SYSTEM, equipped with :
8X15"BPH (B&c 15NW100) ,
4X12"CB (PD12SB30) ,
2X8" (RCF H6000, MR8N301) ,
2X1,4". (18SOUND 1480ND@ B&C
ME90)
The PA is driven by Linea Research 44M20 for LF and Digam K3 and LQ2804 for TOP, DSP is a T-racks FIR 4X8
Filters are :
No lowcut
18dB BW @ 90Hz
12dB BW @80 Hz
12db BW @450Hz
12dB LR @480Hz
18dB LR @1.4K
12db LR @2.8K
With this filter settings no eq is required for the whole system.
next step will be to use 16x10"CB instead of 4X12"CB because the 12" part is the weak spot of the system.

Here is my speaker project.
Its evolving and not finished as yet.
Davidlouis VX8 is the Crown Jewel of this set up
The Millennium tweeter is ripped out and replaced witha chinese paper weeter The Kasun double magnet 3 inch paper cone tweeter much much better than the Millennium's 87db sens, kasun @ 91 db sens
DavidLouis VX8 95db/40hz- say 12khz
DavidLouis W4/91 db sens maybe 80 hz - say 10khz
Seas W18E001 Exce/87db sens (IF THAT!!Seas fudges their sens #'s)l w a Mundorf Supreme SGO 1uf cap
Kasun paper tweeter/91 db sens w Mundorf EVO Silvergold cap 8uf
Something up with 1 channel, weaker vs the other.
So not up to top performance
here you get a idea of what a dual Ful range is all about adding the DLW4 made a very nice gain in soundtsgae.
Diana Krall's voice never sojnded so good.
Will add ina Davidlouis VX8 , might keep the W4 in or if the VX6 does not performas hoped, it will go away and stay with the W4,,,then I may also try the Tang Band W3 1878 to see it performas.
maybe late march I'll have some final design.
Paper tweeter will be replaced witha Davidlouis Be/Nd tweeter(Scan Speak clone for alottt less) late March.
The DLVX8 looks to be a clone of the Voxativ's wood cone speaker.
Bass from the tiny W4 has some kick for a lil guy.
Not sure how to copy a link for upload a pic.
But here is a YT upload of the speaker in action.

The stool looks to have low diffraction, well radiused edges. 🙂
I like the projects looks.
Surprised you haven't gone for the foam spikes/triangles etc as per anechoic chambers!!
I hope you live in the middle of nowhere & away from roads, mines, powerlines, railways, etc for best possible quietness!..
At least I can use these photos as proof that I'm no where near as "extreme" as others in this hobby, & thus my expenditure is minimal...cough, cough..nudge, nudge,.... wink, wink...
Speakers based on Visaton's "La Belle" kit, recently completed (sliders still under cones for positioning); curved cabinet with Blackwood veneer. Vintage Perreaux SM2 pre+PMF2150B power amp, and Dual 704 TT for which I build a new plinth out of New Guinea Rosewood. I had almost no woodworking experience before this and had never held a soldering iron, so it was a miracle it turned out as well as it did. I'm sure there a better speakers out there and everyone has their opinion, but I love the sound of these.
