TUNING Sub - Speaker/GenesisV. Anyone?

Guys, great guidance, TXS, esp. Amcore for all your time. Have placed speakers as per Cardas. Room size (ft) 15w x 25l x 10h. Cabling is Bearlabs, clear and musical. I am now at Ph 45/Vol 39/Low pass 85/ and adjusting. Thanks again!

Pls don't disqualify me from this forum, but I blew one of my front ribbon tweaters (had a spare) -- is this part of the GenV package or (probably) am I doing something wrong? Maybe playing too loud? Anyone encountered this shortcoming?
Txs again

Amcore, thanks for responding. The coil was CUT at one point, and I had no sound coming out of it. I was playing with volume @11:00 (uneccessarily load, for my room, I might add) and the music was Mahler's 5th symphony.
By the way, I have never tightened the drivers -- that's great idea!
How did you realign the tweater? When I opened up the spare to add a new ribbon, there was seemingly only one way the ribbon could fit so that the connectors face in the right direction. I changed the round paper coming in between the magnet chasssis & the coil, using soft coffee filter paper -- but have not tried the driver since.
By the way, re: tuning. I have noticed that in my system, the midrange & upper mid sound a tad better / clearer when the control is set @ 1 than when set @ 2. This may be due to my amplification -- european gear does tend to emphasize mid-range -- but I think it's worth a try... However, I wouldn't change the sub's settings, as per Amcore's suggestions, to suit the midrange control.
I am now @ PH45, Low 86, Vol 36, and feel I'm close. I think Chesky's Listening Tests CD can also be of use here...

Steve, welcome to the happy Genesis gang. Re mid-low: I haven't yet managed to achieve flat coupling between low & mid in my room (15w x25l x10h). However, a flat result below 200Hz sounds very good... My speakers are ~7 ft apart woofer to woofer (centre) -- bringing them closer *does* boost mid-bass. Try speaker placing as per Cardas (depending on room width), and check out the pre-to-subamp cable. This may help to iron out some discrapancies. Also, the sound is more detailed, the further you are away from the speakers (this depends upon yr room size). Hope this can help.
PH @ 180: what does this do for you compared to, say, 45 (my present setting). In my room, phase & mid seem very interelated --- where do you have the midrange setting? I have it at 1 with tweater at near maximum.
