Title: Parabee - Speakers zobel network
Post by: anystereo on March 14, 2011, 05:04:10 AM

Hi,
after about 8-10 years i am gonna work on my system again.  I have a pair of parabees with constant current upgrades, mundorf caps and WE300B's.  these drive a pair of AER coned lowther pm2as oris horns.  I am planning a new speaker project and have been looking at the arpeggio design on diyaudio http://www.diyaudio.com/forums/diyaudio-com-articles/158899-arpeggio-loudspeaker.html?garpg=2#content_start.

Has any one tried a zobel network with their parabees?  Or,  would it even be an improvement? Does any know the source resistance of the Parabees?    I am assuming that Rs is a characteristic of the parafeed transformers?

i'll take my answers off the air.

Another series of questions,  has anyone got a nice line array working with their parabees,  if so what driver and configuration & cabinet design are you using?
