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.
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 ?

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 !
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
