xpat Posted March 13, 2017 Report Share Posted March 13, 2017 I enjoy experimenting with speaker placement, sound treatments, and acoustics in general. My latest adventure has provided some interesting results - interesting because my significant other is never impressed with any of my tweaks. I usually hear the comment “ it sounds good – but I really can't tell the difference”. This time the comment was – it sounds great! I agree. The adventure started after reading an interesting article about Brahms Symphonies on Direct to Disk Vinyl (April 2017 issue of the absolute sound magazine). In the article, the author (Robert E. Greene) states that the least artificial way to record direct to disk is to use the Blumfield stereo microphone technique. In this microphone technique, the sound field - at a single listening position - is recorded in a figure 8 pattern – the mics are almost in the same spot, and the axes of the are mics crossed at 90 degrees. According to the author, “Blumlein stereo presents a real event that the brain can process at the basic level of natural sound listening.” I was very skeptical, but found the concept interesting. (If you're interested, here is a link: https://en.wikipedia.org/wiki/Blumlein_Pair ) To cut to the chase, the author said you can set up an accurate Blumlein playback with the listener close to the speakers, and the speakers separated by 90 degrees. I tried it in my rec room by putting one AR5 on the long wall, and the other 8 1/2 feet away on the short wall. (Both speakers facing forward resulting in a 90 degree setup.) I picked an album where we both enjoy the performance, but always felt the sonics left much to be desired. (This feeling was consistent regardless of the amp and speakers - AR5s, AR6s, AR9s or Sound Dynamics.) The results were quite amazing – at least in my listening space. If you like to experiment, give it a try.... Link to comment Share on other sites More sharing options...
