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??

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.

Duettas are very forgiving when it comes to placement. That is, compared to other Apogees. I had mine all over the place without noticing major sound shifts. With my Scintillas, that is another matter entirely. The position you have them now is really a good one. It's easy to experiment. I would follow Sogood's advice and move them out to four feet just to see. Your amp is perfectly adequate.

I am using one small digital Acoustic Reality eAR for my Scintillas. This amp does it all. I have a better bass than even a Krell can muster, mids the equal of the best tube amps, and highs are sweet. Detail is way beyond all conventional amps, and the leading edge is instantaneous.

Unfortunately, there is no state side support available.
Khrys, only you would read "stupid" into my intentions. All I am saying is the Duetta's embracing sound is far easier to coax than the Stage, or Scintilla, having owned both. It is common knowledge among Apogee lovers the Scintilla and Stage are a lot more mischievous.

I was a Stage owner before I heard my first Duetta. Both DSig speakers were against the wall, one elevated six feet. They had bee crammed into a bedroom. Immediately, despite the negative placement, I could sense the warm, friendly DSig personality.

I got them home, set them up to something similar as Darrel's room configuration, and enjoyed the music. I tried different set ups, to no advantage. That is my experience.

Note that Darrell has asked advice to maximize his Duetta's performance. He seems open to all advice. Since I am a component wonk, I naturally will suggest a change in amp. To answer Darrell's other questions, I am not a fan of dissembowling the Apogee. I would not buy an Apogee that has been modded. I know a person who worked for Apogee for fourteen years that agrees with me. Wires should be of 12 gauge ore higher. Following Bloom's advice, I always bicable my Apogees when I can.

My room is symmetrical. Speaker placement will be complicated in an asymmetrical room. Experimentation is the only recourse.

That is my humble opinion (based on experience).
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.
