I have had them for about 10 years now..... Understand that you can use any Bass System that you want... I use a pair of Klipschorn Bass Bins. I use a pair of Hypex Amps with built in Active Crossover... I am Crossing over at 270 Hz to the Bass Bins.... The Horns have a Passive Crossover (M5 -Orphean) --- The Passive controls the Concentric Driver to the Horn crossing the tweeter over at 7Khz, so the Midrange is brought in at 7Khz to 270 Hz. The Horns are driven by a Pair of Korneff 45 Monoblocks, which put out about 1.8 watts per channel, which is plenty considering the Horns are 115db. I am using about 1/4 of 1 watt.I can highly recommend the Orphean Horn System, as it is the finest Speaker I've had in my System. I no longer think about Speakers.
BTW - Where in Australia are you? -- I spent the 2018 winter (Ours) in Hervey Bay in Queensland.

G'day Cut-Throat,
In semi retirement these days living out of a caravan doing the North West of Western Australia. Ningaloo Reef, NW Cape some fascinating WW2 history around here and after the Cuban missile crisis in '62 ? They installed a VLF Antennae system 19.8kHz which takes up an area 1000's of acres with 13 towers that exceed 400m in height. Still used today for US & Aust Navy ie subs, carriers etc covering the Australasian Indian/Pacific area.
Yep great fishing up this way - Red Emperors. Exmouth sits at around 22 degrees lat, lovely spot to be in wintertime. Perhaps the East coast of Australia next year.
Anyway back to speakers, as per picture my inclination is to go for a corner horn like your bass bin because that's what would fit better in my room because I have natural corners and the walls are mudbricks(solid) and the floor space is around 36sqm with ceiling roughly 3m above speakers.
Berts use of the revelation OB he tells me can be used near walls but not recommended for corner placement which makes sense as they are a dipole radiators. Plus the Beyna 15" driver 4 off per cab don't come check around $500 per driver.
So did you use a Klipschorn Bass Bins or have them copied ?
And are you using the 4592 compression driver in your application ?
It appears Bert these day favors going fully active on crossovers which is fine with me, bit more flexibility.
I was hoping for a cookie cutter approach but that doesn't appear to be an option so one needs to do their due diligence.
Cheers Johno
I have the Complete Orphean System.... WHich is:
Orphean M5 Complete
Includes one pair of M5 crossovers, one pair of modified BMS 4592ND/16 compression drivers and one pair of Orphean horns as complete DIY-kit (as standard without finish).
These is a Passive crossover (M5) for the Driver.
I have Stock Klipschorn Bass Bins. My Active Crossover in the Hypex is for the Bass Bins to the Orphean.
I am familiar with Exmouth area... I follow a couple of fishing guides out there.. The year I was there, I was going to take a trip out there, but it was too hot and the fishing was Off... So, I didn't go...
Cut-Throat, I assume you find the integration between the Klipschorn Bass Bin and the Orphean horn as being to your liking, anything you would do differently if starting again?
PS - Does this look right.
Source digital 2V out > M5 crossover > LF output of M5 crossover to DPS/Plate Amp to bass bin > HF output of M5 crossover to HF Amp (valve) to horns.
Also, you got any pics on how you mounted/supported the horn unit on top of the bass bin?
Cheers Johno
I would do nothing different from what I've got now....
PS - Does this look right. (I've added some corrections)Source digital 2V out > Tube Pre-amp > Hypex Plate Amp with active crossover> bass bin
Also Tube Pre-amp > 45 SET Amps > M5 Crossover LF and HF > Oris Horns with 2 inputs on the Driver (tweeter and Mid Range on each Driver)Note: I have 2 Hypex Plate Amps - 1 for each Channel -- Also 2 - 45 SET amps - 1 for each Channel

It appears that it has a mid and high output connected to the compressions driver. Is there a super tweeter somewhere or does it do something like a concentric driver somehow?
-Rod
Concentric Driver. See attached Sheet....
Ok the M5 crossover goes after the valve amp, makes sense.
Did you do any time align measurement regarding the offset of the horn mouth ie the physical position on the bass bins or was that done by ear?
Cheers Johno
I've done some frequency sweeps using REW software, and a lot of tweaking by ear.
