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??

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!!!!
Darrell,
With all due respect to Sogood51, I beg to differ on one point, unless you are planning on moving to active bi-amping, I would recommend you upgrade the crossover. Since you already have the components, an afternoon's work will be handsomely rewarded by more clarity, more definition and detail, and better soundstaging. Also I found that mounting the crossover on an external panel independent of and placed behind the speaker (I use maple planks) makes a huge improvement in the sound. It is relatively easy to A/B this (once the front has been removed) by detacting the stock crossover and listening. I believe all but the inductor for the bass is mounted on one piece of hard board and this board can easily dismounted from the speaker w/o disconnecting the wiring---I think 2 screws and silicon glue are all that hold it in place. Also I found that replacing the stock pikes with stainless steel cones makes a significant improvement in the sound---this has been probably the most cost effective tweak I've come across.
