Apogee Duetta Signature: Optimum placement

I am setting up the Duetta Sigs in a room 16' x 15' with an 8' ceiling. I have them on the 15' wall 20" from the side walls and 36" from the rear. The distance between the left & right m/t ribbon sections are 7'. The tip back is 2.5" or 2.5 degrees. The toe in is 1/2". Listening position is 9'. What changes do I need to make to this basic configuration to acheive the best sound? I am using an ASR amp which provides 290 watts at @ 4 ohms & 520 @ 2 ohms. The speakers have a single run of speaker wire and jumpered on the back terminals. I have, but not installed the crossover upgrade kit (came with the speakers) for the caps, resistors & inductors. How much difference does the upgrade make? Is it worth the hassel of taking apart the speakers to install it??

My Duetta Sigs had been owned by two others before me, and have traveled through two hands since. I think most Apogee buyers will gravitate towards stock models, unless they know the history of the mod. While owning the Duettas, I tirelessly watched for any Scintilla sale. To me, the Scintilla is the ultimate upgrade.

Muralman, what frosts you most?: that most Apogee owners ditched them or that the company went out of business?(you think these events might be related?). If, as you insist, that Scintillas amplified by the new Euro-norm class D amps represent the state of the art then surely their resurrection is imminent. With breath barely bated more than yours, I await that anachronistic travesty with earnest.

Way off topic, you dredging up old history. Almost all Apogees will have to be pulled from their dead owner's hands. Except possibly for old Quads, I don't know of a more coveted line of discontinued speakers.

The Apogee is so great a speaker, there are individuals that are working hard to resurrect the technology. For instance, Graz of Down Under is presently building a full range ribbon speaker to order. With far more powerful magnets and advanced crossover technology available, the new speakers will be more efficient, and dynamic. You can breathe now.

Hi Darrell,
I ordered the cones from Ed Soler here on Audiogon. He is an excellent person to deal with, and knows the Duettas. His moniker is esoler. Good listening!!!!
