Sorry 8 x Dolby Atmos horn speakers MID freq is from 120 Hz to 1.600 Hz and left, center and right horn speakers MID freq is from 120 Hz to 1.350 Hz with Faital HF10AK + LTH102 for HF for MID is Faital 10PR300.
Yes, 4 x TH1819, front left and right corner and back left and right corner. Each is some 110 kg and WxHxD (58cm x 125cm x 80cm) with 450 liters netto and 4.50m horn path!
It was a temporary test 2-way setup to see how well the combo would pair with the faital 15pr400 woofer. Crossed around 1khz -1.2khz. The faitals do sound nice working together.
To add to the last post. I cross my hf108r at 910 on the b52 horn. I use a steep fir xo, no problems so far.
The 15PR400 is undoubtedly one of the best midwoofers around, which is acknowledged by people like Tony Gee and Troels Gravesen.
Not only Le is very low, but the measured Fs lies between 32 and 30Hz. There's a small dip centered around 1000Hz - which makes 800-1000Hz a logical XO point, but apart from that, its response is fairly clean up to about 2kHz.
No wonder this 15" is an ideal partner of either the HF108(R) or HF10AK for a (nearly) full range 2 way.

Following Earl G. input about home hifi needs and impedance curve being irrelevant in that context, indeed why not pushing the 10AK till 800 hz where a 15" whatever the 15PR400 would be better than 1000 or 1200 hz ?
If the compression can go to 112 db at max spl raise on dynamic peaks that's ok at home ! Question is do they keep their good tweeter sound when pushed as low ? Or safer going to a 1.4" ? All the answers you specialists said is that many 1" are ok that low ! But how a horn patern at 800 hz to cut-off a 15" patern at same frequency ?
Tony Gee has a 93 db after filtering the 15pr400, I assume some bafle step compensation ? The compression has plenty of headroom with such a number...

Thanks YSDR,
Auto-Tech is a little expensive as far I remember... very inexpensive human cost in Pl but the prices are danish at A-T... not for my wallet, maybe DIYSOUNDGroup instead and they are fun guys there, I like what they do. Autotech is premium finish : gloss colors cars painting, fibers material...
The Auto Tech Mumy is gorgeous, exactly what I would like about aesthetic.
What your todays loudspeaker is made of YSDR ?

Yeah, Auto-Tech is pricey, i soon gave up on them when I heard their prices.
My speaker have a HF108R CD with the STH100 horn in a 3 way configuration (6.5" mid + 12" woofer).

Other options include the B&C ME45, JBL 2370 and the cheap Celestion H1-9040P and its derivatives, the Monacor MRH200 and the Dayton Audio H812.
The B52 QSC clone would be the better (sounding) horn though.

Cool speakers you have guys, mine for the moment is a "poor" 86 db/2.83V clasic 3 ways towers... But I'm sure a cool two ways with enough sensibility will come. Dynamic, yes, only if the soundstage is as good as a classic "low spl" speaker . . . which asks I uderstood : even more knowledge when high efficienty and horns are involved . Basicly from my seat as a non specialist, basic enthusiast !
2x FaitalPro STH100 and 2x FaitalPro HF10AK in my shopping chart. I hope I will not regret the HF108R 🙂
With tractrix 80x70° horn the walls, ceilling and floor reflexions are outside a sweet spot ? Saying a 2.7 meter floor to ceilling and horn at 1 m f the rear and side walls, sweet spot at 3 m ? We often hear 90x40° is an appreciated horn pattern -outside more mdern designs I mean- ?
vertical 80° at 6k hz then gently beams 40° 20 khz
horizontal 80° since 2.5 k hz to 7° 20k hz

I recently ordered a pair HF10AK in 16 Ohm and will do some testing on my JBL 2344 - 100X100° horns.

Just purchased Faital Pro HF10AK and Beyma TPL150H.
Plan to do some general frequency response measurements next week.
