Hi. Any listening impressions? Cabinet volume? How low do they go in-room?
They look very nice.
Thank you
Danny
Cabs are 110l, about 30-35hz in room and close wall. Midrange is pure gold, crossing somewhere 1200hz. Bass is super fast but there could be little more of it. And there is not any extra sparkle on upper register..some like it, some not. Imaging is surprisingly good, didn’t expect that it would be so wide and deep. Nice speakers, I like them. Dual subwoofers would make them VERY good!
Thanks! Starting point was Wayne Parhams 4Pi xo, since I use different horn and driver I had to do some rework. Otherwise I used Jantzen caps, air core coils and there’s one huge vintage 100w ceramic resistor for mid/bass.
here is my mini dsp 4x10HD based 3-way system :
- SPL dynamics xtr380 subs (sealed with foam plugs in the ports) 3cu.ft LR24 80 hz, crown XTI 4002 ( 2 ohm load )
these car subs are not my first today (high mms and qts) but the sounds good to me , at least as long as I have nothing else to compare with yet 🙂
- Faital pro 12PR300, sealed 1 cuft 120hz LR12 / 1250hz LR12, Rotel RB 991
- Faital pro HF108R / LTH102, 1250hz LR12 , Rotel RA 980BX
the measurement is both channels at 70 cm distance on axis (mic between the drivers) 1/10 smoothing

Before these strait midbass horns I had Bruce Edgar's downsized "Show Horns" and pretty satisfied (not so when playing cello lines). But I used to look after a strait horn to replace them. Not that eager to DIY one of the projects available here or else (not having a proper workshop) my attention was captured by a pair of empty 12inch horn enclosures on US eBay (see the picture). I also found the originals which are made by Audac and named HS212 and got a good deal for a pair from Germany.
Initially I wanted to eviscerate the inside coaxial HF horn but --as it also play phaseplug role-- I let it in place and just used all speaker as it is crossed at 600Hz and 100Hz with the rest of my 3-ways horn system. Now the system is rock solid, I can throw on it anything and doesn't complain at all. All percussion instruments, especially piano which I know how it should sound, are superbly reproduced. It is very liniar till 110Hz where it falls sharply.

Thanks D. Very cool looking horn. So it is playing from 100hz to 600hz? I wonder how it would sound with a good compression driver.
Did a little research on these. I think I'm going to look for a pair. With a sub or two they may work well.
Welcome DJN. Not sure about using it with compression driver as it has large throat for a 12 inch direct radiator in close back chamber. Adding subwoofer you can use it full range --it's coaxial HF horn is taking over from 1.5kHz-- it should not be that bad compared to a synergy which looks cooler.

That horn has a compression driver attached from the factory it says. Didn't say which one so dont know the quality.
New pics
I opened the back of the horn and found the HF drived being D44E, no idea what maker.

I'm wondering if the relative big volume in front of 12" driver makes the system go smooth and lower (110Hz) than dimensions of the horn suggests (kind of a 4th order bandpass), or is just a simple LP acoustic filter (how high?).
