So, you use DCX 2496 for deals but not for crossovering and your crossovers are still on analog domain, right?

Romy, I do everything in the digital domain so I use DCX 2496 as my crossover as well (but analog SS pro amps). I know you're no big fan of digital crossovers, can you point to where I can study the advantage of passive crossovers over digital? I've only taken audio seriously a few years ago so I really don't know much... thanks.

I do not have time now go into details but generally using horns like your wider and with more decoupling from back wall create many great advantages. One of the most prominent is a depth of imaging (not even depth geometrical but rather the “quality of death”), proper curvature of back image, more proper imaging allocation, proper spread of dynamics within imaging, minimization of loudspeaker-crosstalk and introduction more binaural effects into stereo reproduction, minimization of horn’s reentry colorations and many others…

Thanks, that's enough reasons for me to have to try it out

Yep, the 50hz-60hz straight horn is the goal, isn’t it? Might I ask you what you feel that it needs to be invariably round horn? You do have the proper 150Hz horn at the bottom of your system and it will “ground” the upper-bass imaging to the vertical center. So, your 50hz horn most likely will be sharp-crossover at top knee. If so then roundness of this horn might be no justifiable from cost-per-transaction perspective. I defiantly do not advocate rectangular horn over round horn but the rectangular bass horn do have own advantages: they sampler and might be positioned closer to MF, they might be better coupleable to boundaries, they require much less blood to make and to maintain them…

Well... like I said above I don't understand much about audio/horns, but I was getting great results with round horns so I thought I'd do the same with 50hz horn. You're right that the 50hz horn will be "sharp-crossover at top knee" so perhaps I'll start another thread and discuss more about it when the time comes. (I have a +10db gain at 50hz due to left/right walls being 21'8" apart I'm hoping that somehow I can use that to an advantage when I make the horns.)
