Subject: Bass Trap question
Hello
I¥ve set up a new control room which measures about 2,3m (y) x 3m (x) x 2,6m
(z).
Right now all surfaces are still untreated but I can already tell that
theres a serious problem around the 110hz to 120hz zone.
This modal response is obvious while listening to music as it is while
playing sine waves at different keys (resonances). Theres a considerable
increase in volume at that 115hz range and all corresponding octaves.
Of all the bass trap devices I¥ve seen the RPG Bass Trap seems to be the
most efective at the lowest part of the spectrum with an absortion
coeficient of 1.12 sabins at 80hz.
Is there anyone out there with a similar problem to mine who can share some
pratical knowledge with me? Since the RPG Bass Trap is kinda expensive I
don¥t mind spending the money if its the right (and only) solution.
Let me also point that for the price of 2 RGP Bass Traps (which is as far as
I can go) I can get 4 small-sized tube traps but its peak is situated around
200hz to 500hz, an area that I¥m thinking on treating with other materials.
