(... Why do I feel this a residual standing wave - flutter like problem...) If you don't put the rug on the floor but leave the 703, is it still there? |

Just checked. Yes, it takes the rug and the 703 to kill it. |

I've a very bad experience with drywall, basically to much of it in a room and the midrange will be sacrificed. Thomas, have you this experience as well? |

I think the 703 in the ceiling is too dense. It has a too high surface impedance, which is reflecting mids. |

Do you have any brand/model information on these? |

Being, at this point, heavily invested in 703, this is not something I wanted to hear. What material do you recommend instead? We'll try your suggestion and let you know. Thanks so much! |

Thomas, please trust me the OC703 is a staple of all of our studio designs. It's surface impedance has never been a problem. |

Even at a relatively low angle of incidence, the 703 (at 3lbs/ CF) isn't a problem with mid frequency reflections. It would certainly not be the cause of flutter issues at the frequency in question. |

The measurement shown in the graph below was taken in my living room, and shows the change in response with and without 1-inch thick 703 covering a wood "wall" placed nearby. The angle was about 45 degrees, so clearly 703 works well even at an angle. |

My problem was not a question of incidence though, but of surface impedance |

Update, FWIW: Thinking and reading around on this forum, came to the conclusion that trying to make a room this small very live is a mistake. |
