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??

Thank you all for your excellent help!!! One more question please.

Which would be the best audible improvement: Installing the crossover upgrade OR purchasing an Apogee external DAX ????

Once again, Thanks for your advice!!!!!!!!!

My amps power suppy (The ASR Emitter One Exclusive) is enclosed in a separate chassis. It also has a pure dc battery supply that powers the preamp section. The amp can provide 2 x 700 watts at 1 ohm so I don't think it is lacking. The suggestion of moving the speaker out to 4 feet makes sense. The backwave from the panel may be bouncing off the rear wall and since it is out of phase with the front wave launch it could be partially canceling the bass energy as it meets it in the front of the speaker.

The jumpers I know have to go, It's just hard to spend another 1800 for another set of cables.

Thanks for the feedback.

Thanks for the tips! I moved them out from the front wall to the recommended 48". This seemed to help the bass and if I'm correct, seemed to deepen the sound stage quite a bit! The upgrade kit contains some big mama inductors 2" x 4-7/8", 2 x 3-3/4", and 2 x 2-1/2". If anyone has done this mod, will all of these fit inside along with the 14 Auri caps?????

If I build something external, I don't want it to look to micky mouse.

Also, RlXl;
Please tell me more about the speaker cones as I think the factory legs just kinda float on top of my carpeting. Where did you get them? Pictures of your speakers with the cones would be great!

The suggestion of bi-wiring is something I definately will try!

Thanks!
