They are the original corner types.  When I got them they were flipped up side down with EV T-35 tweets and EV-T25 mid driver with 8HD horns in the mouth.  They also had the EV X36 and X8 crossovers and L-pads.  The woofer is the EV SP-15.  I left the woof and took everything else out, flipped them right side up and am now using the Edgarhorn 350hz midhorn with JBL 2441 driver and Heil tweeter.  All this is tri amped through a Behringer CX-3400 into three tube amps.  They sound amazing from top to bottom.  Plenty of tight and low bass with a little dip in the midbass area.  I will be trying the JBL 2225 woofer next week and the Lambda MT15 woofer the week after that.  

Very nice! Thanks for sharing. How do you like the Lambda drivers? I have a few on order from Acoustic Elegance I hope to receive soon.

PS Are you sure the Edgar horns are 350hz cutoff?
