looneys - delay times

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

   Anyone help with a start point on delay times on a Berry ultradrive for looney bins assuming tops sat directly on top forward facing on outer edge?  I'll tune em up once installed but need a starting point!

Cheers

Pav

	We started with 1600mm for our 1850 horns based purely on the horn length - not quite the same design as the Looney but similar. We now use 2344mm after doing some testing with the DCX auto align. We cross at 130Hz to reflex loaded twin 15" cabs, so that delay figure is very much specific to our set up and what you need may be very different (all depends on the phase shift of your mid cabs at the x-over freq if I understand it correctly).

	Cheers, I'll look at somewhere between those two figures then trust my ears. Did the autoalign work, and if so how did you get it to work??

	Yep, autoalign did a good job. Used the berry ecm 8000 mike and these instructions. Studio45 posted a good description of how to do it without auto align here a little while ago. Its been discussed here a lot over the years - use the search facility :-)
