RX-Z7 with Polk speakers
I finally got the Z7 last week. I've been tweaking the sound stage and noticed the automatic setup (single point) on the Z7 set my fronts and center to LARGE setting.
I have Polk RTi10's for front, CSi5 for center, PSW505 for sub and the FXi3's for surronds.
I noticed today while playing the dark knight blueray, while the fronts/center set to LARGE sound setting, the speakers really seem to push too much at times. The 2 - 7 inch woofers were really moving a lot. I hear a rattle and over exert on the fronts, not like they are popping, but over extending to almost a distort in sound; squeaking.
I changed the fronts and center to SMALL sound setting and set crossover to 80hz.
All of the rattles and over extending is gone. It still sounds great.
The polk manual says recommended BASS setting for the RTi10 fronts is LARGE.
On my previous amp - pioneer - everything automatically was set to SMALL and never had any issues.
My question is how does one know the proper settings for sound setup and does it matter..? Any opinions or suggestions would be great.
Thanks.
