Hello Hakn,I did the exact same mod a couple of years ago. Called it my version of the "Thermionic-2". Great sound. More refined and controlled. Loss a bit of "liveliness" though. I think one of the things that make the Studio-2's sound so great is the simplicity of its crossover. Somewhere between zero and first order.
I've since put this set up away and moved to the Theatre-3, so I can't have you the compensation network values. Wayne's crossover document should give you the values though
What horns are you using with the 2446? I had 2380A's on my 2445 for a while, but found my DIY smith horns to sound nicer. Less edgy at high volume and larger sweet-spot.
