Confused with Clibration

I had calibrated my system with Avia before, but then I changed my surround speakers and replaced my Sony receiver with Panny XR57.
My setup now includes Ascend 340s for the front soundstage+Ascend 200s for the surrounds(They are small bookshelf speakers) + Mirage s12.
I calibrated the system with the receiver test tones on Panny57 and setup my surrounds +4db to level match with front soundstage. I thought this was ok because the 200s are a little less efficient than the 340s. According to Ascend website 340's sensitivity is 90db and 200s are 87db per 1 watt/1 meter)

I was trying to use Avia again today and the Avia test tones are very different. I had to setup my surrounds with +9db to level match with Avia test tones and they are still couple of DBs lower than the front speakers.

How can these 2 test tones be so different. I tried the receiver test tones again after calibrating with Avia and my surrounds are much higher than the front speakers per the Panny tones. I'm going crazy. I'm also little worried about damaging the surrounds by running them 9 to 10 db hotter.Can someone explain the difference?


PS- All the speakers are set to small and the xover is set at 80.

Another update. I tried to up the surrounds by +11 but still can't match the front stage. I'm trying to calibrate with 70db and the surrounds can't get past 68. They stay the same at +11 or even +7 at 68 dbs. When I run the receiver test tones, I hear a significant difference when the surrounds are cranked up(the SPL meter shows it too).
I replaced the toslink with Coax, but result remain the same.

This is getting really interesting. May be I need to borrow DVE from someone and see if it will make a difference.
