Hi All,

Cross posted with intention to delete original post. With a new house comes new opportunities! Current system
  • Pana XR-SA55 amp capable of 7.1 (5.1 + 2 back surrounds)
  • Front: Mirage Om 50
  • Surround: Energy Eclipse 14”
  • Sub: Velodyne CHT 8 (30-140Hz)
  • Front and surrounds have a good frequency match around 45Hz to 20kHz
All these possibilities hinge around various options available on EBay (2 or 4 Nanosats @about $40/speaker) or locally (2 Nanosats plus subwoofer @$100; also have a friend with a 7 speaker Nanosat set plus sub). Possibilities:
1. Reconfigure 5.1 system. Replace surround Energy speakers with Mirage Nanosat (110Hz up) to achieve a more general surround than from the front firing Energy speakers. In terms of sub, would I match the sub cross over to front or surrounds?

2. Set up 7.1 by using some combination of the Energy/Nanosats as surround/back surround. Using 4 Nanosats might be an option as well.

3. Set up 7.2 by adding an LF100 sub (slightly narrower range than CHT at 40-120Hz). The frequency response of both subs seems very close. (I am assuming I would constrain frequency range of both subs to 40-110to220Hz?)

4. Future…set up an Atmos arrangement by adding 2 ceiling speakers plus of course a new amp. Assuming the Nanosats would suck at this.

Constraints:
  • Apparently Dolby says all speakers should go down at least to 80Hz. If that is critical, I’ve not seen many surround speakers that go that low.
  • Ideal distance between surround speakers is 10’ (on pillars) but could be increased up to 16’
  • Back speakers can either be about 2.5’ behind surrounds or about 10’ (due to ceiling configuration)
  • Ceiling height is about 7-8’
  • We just had to have a bunch of repairs done for a water leak…no more construction beyond cable runs.
Thank you everyone!

Steve
