   Hi Stu! 
The T36 is a 15” FLH and has a rising response, lacking bellow 50Hz; The T24 (I’ve also made one) is a BPH loaded with a ten (You know it) with a valley just were the kick drums work, raising more than the T36’s. 
The SPL chart at the BF forum archives indoor...

One cab response/four cabs charts at Pi shootout

-With Hogs there is no need of EQ, as they are near flat from 35 Hz up, single near wall; when I’ve made the second, WOW! Than the third one, and other WOW. The fourth comes and 2 WOWs.
Imagine you can hear a PA sub woofer with the sound like at your HT, and you can push the sliders up without pain; The round fat sound like a big reflex with extended response at 10% of capability, but with a punch like to a FLH at full hell power.
It’s also a experience hear ACDC, Dire Straits, Yes, Deep Purple,… All kind sound good of music thru them.
The 18LW1400s have a lovely clean sound loading them.
Low-cut at 35 Hz. Also played at 25Hz but I like the loudspeakers and will not find out the limit (not worth).
Upper crossover point point between 100/120 Hz. 

-The 1850s with modified Vb (driver used has a qts 0,21, 8 MM x-max, BL 24,5 Pe 800W) also play very well, but with electronic music they really show up. At 750w/cab no problem with low-cut at 40Hz.

The story about a comparison to a four stroke engine confirms...

Crossover points; low-cut at 40 up to 120 Hz at maximum;

Regards,

	You must add 23 dB to the Tuba 36 charts because the charts are at 10m@2V!

	WE-plating madness: I better patent this degree of bending the v! Well as I just reloaded pd.1850 horns & DK "tractrix" (like 18" hd15) this test startet growing through our heads and up towards the ceiling: I think it could use some more plates, but then we'll loose the sweet spot, I tried to build it up with some thought, starting from below: HOGs with above 90 degrees opening to keep the two drivers from directly front firing, aiming "around" the corners. Lowest frequency (30-35hz?) should be better acieved using a plate on top of HOGs as there can be no coupling with pd.1850 horns above at this freq. But if we rearrange we will miss the sweet spot:-) -testing Wednessday. I think cancellation happens at ½ wavelength distance, in this case 1,5m'2=3m 320m/s / 3m = 106hz, a freq I'm not planning to use. PD.1850, to be delayed to couple HOG mouth, same degree v, I don't know how low it can go, They're four now! But the path gets no longer that 40cm extra. AND the red ones stole it's we-plate, and that red one is not as wide. The red short horns is kind of a joke, but delayed down to the rest i think it will couple in a mean heigh. I don't know if the end area is big enough, I should put an I-PLATE there to prolong it. WHAT BOXES: HOGS: From Father Francis loaded with Void Pd 1850 horn: Loaded with pd.1850 "Tractrix" aka TT1000 (after fane-driver i guess) : Loaded with L18P300. WHAT CROSSOVER: Don't know, will test, Ideas? Hogs 30-35 to 70-80 pd.1850: 45-100 tractrix: 50(bph?)-80(flh?) to 110-180 Altec 416: 120-400 ev sh1810:250-20k The tops are pointing outwards I don't think and don't hope the post 2m in front of the stack will be a problem. After this thursday gig we will do a little more serious testing with less factors (or more)
