Thanks for that info. Rotating 90* would put the subs firing into either my center or left or right speakers. So much info. Brain overload. Been reading all morning - Time for a break. smile.gif

Can anybody assist me in speaker placement and seating placement based on the following information entered the Room Mode Calculator that was referred to in this Forum.

 I must admit this is quite confusing and has confused me even more after reading through this thread.

 

 

I am trying to set up a 7.2 system. The speakers are as follows

 

  • Front Left and Right - Klipsch La Scalas
  • Surround Left and Right - Elac FS68's
  • Surround Rear Left and Right - Paradigm Atoms'
  • Centre - Paradigm CC150
  • Subwoofers - Paradigm PS1200, Paradigm PDR-80

 

Any help would be greatly appreciated.

This program is a lot more user friendly in helping to determine speaker and listening position placements for a given room...

The problem with mode calculators, and programs that use this type of data, is they assume the walls and floor etc are massive and reflect fully at all frequencies. Real walls don't behave that way and the resonant frequencies shift. So the only way to know for sure where your speakers are flattest is to measure the bass response at high resolution using appropriate software as you experiment. Anything less is just guessing. This might help:

Yes as Ethan says... those calculators can give you a rough idea but measurements to confirm and final adjustments afterwards are almost always needed.
