If I did upgrade amps then id go straight to a solid 400wpc @ 8ohm amp.

Anyhow I am posting because I am sort of considering selling my Stage 4 Pis because I have this bias that I cannot shake...I keep looking at that huge 15" driver and that small 1" tweeter and have to think I am missing something.

Am I?

Spec's don't tell the whole story, but it's a good place to start. According to Eminence's SPL graphs, the Omega 15 runs pretty flat up to 2000Hz, while the PSD2002 comes down to 1600Hz. So, there shouldn't be any holes in between.

Have you performed a frequency sweep to hear if there are any audible holes in that area? If so, try reversing the connection on the tweeter to see if it makes a difference.

BTW, the tweeter's exit throat is 1". The diaphram in the tweeter is 2".

Also consider that the Delta 15 has a thin light cone which means the cone is flexible at higher frequencies, so the total mass and size doesn't prevent the higher frequencies. With strong paper and at the associated moderate power levels this is usually an asset as I believe is the case here. This is why they don't shut down at 1000Hz like the Magnum or Kilomax. As for the HF driver its 2" once you get down into the guts. Horns load that light diapragm to make it "feel" bigger and heavier, but up high the throat is to big to resist that huge honkin' magnet, yet small enough not to cancel out the top octave. So you still get enough top end. Most bigger drivers have no good top end.
Enjoy 'em!

There is less midrange present when listening to my Pi 7's too.

Most speakers accent the midrange. How often do you listen to a car radio or radio at work that doesn't have any/many frequencies below 100 hz being produced? On many systems you listen to drums and they are background noise. When you listen to drums on the Pi's you can tell when they're getting pounded.

I was looking at those little Bose cubes the other day paired up with a sub in a restaurant I was at. They made decent sound considering the size. The midrange was certainly there. The drums were definitely background only. Speakers like the Bose cubes are designed to make the midrange that much more present and that is what a lot of people are used to listening to.

I prefer the Pi's though.

I have come to the conclusion that my room is greatly handicapping my Stage 4 Pis.

Hopefully some day I can give these speakers the room they deserve.
