A time delay of ten milliseconds or less is likely to be experienced as smeared sound. A fifteen millisecond time delay would be ideal for many people -- the brain will process it as if it were room or hall ambience.
room acoustics question
Was reading the latest TAS or Stereophile and got to thinkng about room acoustics (again) and I have a couple of questions that the readers might be able to help with.
1) Is there a math formula that can be used to calcultae the arrival time (and hence help with room tuning) for driver responces? This may be even more difficult as I use Apogee Slant 6s and the radiation is bipolar. 2) Should the back of the room be kept "dead" or should I be using diffusion or reflection to increase the staging and depth? Currently the back of the room has somewhat thick curtins with 1 48" Room Tune opposite the right speaker, I also use 3 additional 48" Room Tunes (the use of them has been a huge help) behind the speakers as well as 4 Corner Tunes in my system, sound is quite good but I am looking to increase my over all experience when listening. I listen to Blues, soft Rock and New Age. (full system info can be seen in my listing). Your opinins would be helpful and naturally I'm trying to be cost effective as well with my choices. Thanks---Ray
