Here are 2 bass horns ("stand" type)calculated by my method (at my knowledge there is at the moment half a dozen French audiophiles using such bass horns):

builder : Frederic Lebas :

builder : Jean-Paul X. :

Also here attached a projection on the floor of a "stand" corner bass horn (in red).

Total width 3 meter, depth 1.5meter.

Best regards from Paris, France

Thankyou Jmmlc, they are some well thought out designs which I am sure were years in the making.

I think i will use 1 or 2 15's in a more standard enclosure for now, with some equalisation. I need to confirm the quality of the dcm 50 and the T500A mkII and would like any opinions of users of either of these components.

Like all conical (asymptotic) horns,
it needs a mouth bell to avoid "honk".
Look elsewhere!

Yes, I have been trying to convince myself the AH 300 would be suitable, I love the aesthetic simple beauty of them. However I am not will to have a honky horn. The Azura horn or the LeCleach'h horn in the confusing bulk/group buy look the go.

I've heard the AH!300 on a couple of occasions -- both times with the RCA MI-9548 drivers. Zero honk. If I had the room, I'd own a pair.
