Just picked up some 291-16 drivers. Replace Symbiotics?

[yelmite]

Hello all,

I just picked up a pair of 291-16 large format compession drivers with the symbiotic diaphrams along with MR94 horns. They are replacing 511b horns with Symbiotic 807 drivers. I was considering replacing the 807's with 802's because the 807's just did not have the detail I am seeking. Anyway, I put the new gear into action and everyone in the house immediately noticed a significant improvement in resolution. So my question, will the resolution get even better with new aluminum GPA diaphrams? By the way I tri-amp with SEP amps for high frequencies and Solid State for the Bass; the new drivers and horns are stunning.

the 291 diaphragm is better than the small format Symbiotik.
But you will notice more "air" and a bit less muffled with all aluminum.
