Someone told to forget cerwinvega drivers, why is that?  Few cv driver specs seems to be well in the limits - even more than some 1860's like having huge BL of over 50, xmax 19mm etc.. well those drivers are not commerically available however, just wondering about scoops equipped with such a monster horn-drivers like L-1816 :)

I read somewhere also that the peavey black widows (certain ones anyway) are fantastic when horn loaded! Might be worth a little shout for lower powered scoops (?)

That link does not work for me and checking their webpage at https://www.gearsourceeurope.com/catalog/brands I cannot see CV listed there

BL of 52 out of that small magnet? No way.

Magnet size will say nothing about BL.  I have seen huge magnet drivers having really low BL, and small magnet drivers having high BL factor.   It is all about the actual voicecoil and magnet design / structure that makes the total BL. 
In the past, I had Cerwinvega XL18s driver, magnet was moderate size. BL was measured well over 30. Once I took off the dust cup and there was really really small gap / clearance beetween the coil and center pole! Propably 0.2mm or so. Less clearance = more BL. 

Oh man that driver was fast and accurate and made lots of SPL in std BR enclosure. I really miss it.  T&S parameters were pretty weird, I put those parameters to my enclosure sim and it gave optimum sealed box volume of something like 15 liters :D
If I can find one, I will surely test it with a scoop!

Don't forget that BL doesn't tell full story about speaker power and power output. For pure force factor,you need to use (Bl*Bl)/Re as voice coil resistance and thus current and actual power flowing trough will change the outcome. Also Bl across the coil excursion can vary a lot. Same as suspension compliance, taking out some performance from the motor. So small signal value measurement wont tell you usable truth eiter. Here is where Klippel comes in, providing additional data. But it takes even more to properly evaluate speaker capabilities. On top of that, the enclosure has the final word. Bl is good, but cannot stay alone in the evaluation process.
Nikon and Canon people should not be married to each other. Why did you let this happen?

I was just surprised that CV would be able to make such driver, that is all.
