LOW FREQUENCY DIP?
Posted: Thu Jun 26, 2003 3:06 am
Hi,
I've found a low frequency dip in my control room at 80 and 100 Hz. 6 db down at 80 and 9 db down at 100. There is also a rise of 3 db or so at 200. The room has a low and high celing, the low celing is above the monitors and the high celing is above the mix position. The dimensions are as follows:
low celing 89"
high celing 118.5"
front to rear wall 189"
room width 233"
The side walls taper in twords the front wall which has a width of 193".
The rear wall is covered with rockwool hidden behind fabric drapes, the side walls are the same except for 50% which is covered with light T&G timber sheeting, the front wall is also T&G sheeting.
Basically it is a room within a concrete room.
Any ideas on how to improve these dips would be appriciated.
I dont even know where to start looking for the source of these problems.
Thanks in advance.
