Recording Fenny Poppers

Hello all, just seeking some quick advice;

I want to record the next 'Fenny Poppers' custom this November (Fenny Stratford - Wikipedia, the free encyclopedia), which are essentially, small cannons. This need not be such a critical recording, as it is just for my own enjoyment/archive, but what I am planning to use is at least a pair of dynamics (thinking Beyer M201 TG in A/B or adjusted to taste) and a pair of MKH8040s in ORTF.

I am just a little concerned as to how the 8040s will handle the SPLs and whether this could cause damage; I see the 8040 has a max SPL of 142db but not at all sure how loud these things are! On the other hand, I am much less concerned with the Beyers performance with regard to high SPLs.
I do not plan to get too close, perhaps double the rough distance of this video (below) or further (?), as I am just as interested in the resulting reverberations as I am the 'explosions' themselves.

Any advice is very welcome.

Thanks!

What I have seen posted by those who know is that analog is the better way to record explosions. Hopefully the movie RE's will chome in and tell you how.

Thanks; Just to add, I'll be using a 744t and Mixpre. Thinking to Run M201>Channels 1-2 (still open to suggestions regard dynamic mic choice here..) 8040s>Mixpre>3-4

I *DO* have a 2 channel Uher Report IC aswell..

MKH s will take plenty of level,though the classic have a 10dB pad which is useful
I have recorded cannons close up with a MS pair (40/30) with M facing away to pick up reverb and slap ,this works well.
I also used spaced omnis with great results

Thanks Rolo; matched pair MKH classics would have been my first choice, for their -10db pad.. alas, don't own any apart from an MKH30. MS at 180° is an interesting idea; But I use an 8040 for the mid. Perhaps reverse OTRF will do well to attenuate enough of the shockwave and catch the resulting reflections.

MS is better because of its ease of Rycote ing

Thats good, I used to record quite close, never had and overloading,but did engage the pads.
The diapraghms are Telflon coated fabric I seem to remember....

Not sure if it will help or not, but on the 2 disk version of Master and Commander, there's a long bit in one documentary about how they recorded the cannons. The disk also has a cool interactive bit where you can select each mic pair individually, or in groups to hear the sound of each one. A part I particularly liked was how they used a mic, pointed at the ground about 30 feet away, parallel to the cannon. It captured some really good low information. That actually happened as an accident, because the engineer was just casually standing there, with the mic he was holding, pointing down when they fired off a shot.

Boundry layer effect
An MKH 816 laid on the ground was remarkable for that.
