Have a set of Sovereigns with the S8r that has the 375horn, and 075 tweeter,

any guesses on an ideal set of crossover points and slope for Triamp application?

I'll be using a Marchand XO with a Mc240 on the Horns, 225 on the Tweets, and probably a Crown or QSC on the 15"

For a starting point JBL used 500Hz and 7kHz in the S8R. Many would start the 075 higher.

should I consider pulling teh LE15a and replacing with a 2311? If so - what would you do with that passive radiator?

I was also considering getting the 077 at some point (or the pro equivalent)

and putting the TAD horn you recommended on the 375 - should wake those suckers up something fierce.

I will keep all the Original stuff as they do sound really good - even as they are in that horrible box.

Hi Mr.Widget,

I have to agree with You that for the short horn&driver combo like 244x abd 2311 horn but WITH 2308 LENSES TOO, higher crossover frequency such as 1200Hz, woul de better solution, but I can imagine that 244x&2311&2308 , for home level listening, 800Hz ( 2nd or better 3rd order HF filter) would be quite acceptable solution, as a compromise when 15inch bass driver is used such as LE15A, 2231, 2235, or 2216Nd.
