Dear Marc,
I never heard what its like in your room but I really wonder Why you are so crazy with this bass thing . Most of the times we cant win it all. I wish I could have such excellent bass so low down the ground not coming up above my waist but that's not going to happen given what I am not willing to compromise. It would be very interesting to me to see you try shooting for the unbeatable on some sound aspects in your system rather than seeing you try to win it all with what available in your hands.
Regarding small horns. I have heard the Cessaro Wagner small two way horns that sound two thumbs up in a room even bigger than mine. It was playing with Thoress amps, pre, phono and a Brinkmann. Just didnt have the scale and the level of energy as my big ones. But frankly that is generally a difference between a big speaker system and a small one. My point is don't "over think." It will lead you all over the places.
Do the WooZaaaa thing while exhaling. Be Zen, stop making out with Bonzo and you will find your own nirvana.
Best regards,
Tang
The Cessaro Wagner is an interesting speaker. My Odeon La Boheme are a similar design (i.e. 2-way horn loaded with front horn tweeter and back horn loaded mid/bass), in terms of size and output. There is also three designs from Bastanis that are similar and in the right setting deliver great sound. I have found that this kind of horn bass is very agreeable sounding with huge punch in the midbass, although it doesn't go super low...in my room it is good to 35 Hz or so. The Wagner will likely make a quite large scale in a room that is simply too small for your huge Cessaros. If you have the space though, a well integrated big speaker is definitely the way to go...
