dispersion on xtros

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   ive noticed recently how if xt8 horns are installed in Xtros, they seem to have wider dispersion than the td245 horn below. 
i don't know if this applies to the original conical horn too. 

i think 60h on the td245 is actually a bit optimistic.

it's easy to get really even and  fairly wide coverage with the XT8 horn midrange with just 2 boxes. 

has anyone else noticed this discrepancy? or is it just me? - not necessarily in Xtros but in any box with xt8 and/or beyma td245.... 

perhaps csg can comment with  the boxes he build last year?

	Is it possible that the effect will be perceived to be stronger because of the on axis HF beaming you'll get from the TD245? I think phase plugs like in the xt8 would reflect quite a bit of HF energy out to the sides, as the plug is quite long. Doober or Centauri might be able to comment on this. What's the x-over frequency? From specs TD245s look like 60degrees down to 5khz, and by 2khz they're around 80degrees. Obviously these measurements weren't taken using the exit angles of the recommended B&C DE500s or CSGs RCF neos, not sure how much that'd impact things.
