This is a common problem. Almost certainly = one or more room dimension(s) is at - or very close to - the wavelength = of a note of the D chord. If it's too much of a problem, then try = moving the speakers - or, as a last resort, install a tuned bass trap - = there are a number of books on home studio acoustics that wil give you = the required design info.   Hope this helps   Every Blessing   Tony ----- Original Message -----=20 From: Gary Black=20 To: DIYAPASON-L@pipechat.org=20 Sent: Wednesday, September 10, 2003 5:19 AM Subject: [Residence Organs] bourdon 16' vibrations     HI List, Is it possible for a room to respond well accustically in one = key better than other? My room that the organ speaks in here at home = seems to "bloom" with sound in the key of D. Am I hearing this or is the = first step to the padded cell? Thanks for you input. Gary

An organ pipe is, after all, a 'tuned room', and the resonance of the room the pipe is in will affect its tone. Bass tones tend to shake nearby objects, rather than projecting outward. If the = room is resonant to the 'D', it might enhance its tone with sympathetic = vibrations.     At 11:19 PM 9/9/2003 -0500, Gary Black wrote: >HI List, Is it possible for a room to respond well accustically in one = key >better than other?
