Correcting low-end peaks/troughs
Posted: Wed Jun 17, 2020 6:06 pm
First post - I read through the posting guide, so hopefully I have everything covered!
Overview: I've been recording/producing for 20ish years. Currently non-professionally in my home studio, and I want to fix the low-end peaks/troughs in my monitoring.
My room is fairly well insulated, neighbours are far away, loudness is never an issue.
I'm currently using an old Blue Sky System One - 2x 6.5" satellites, and a KRK Rokit 10s (the original System One sub died on me a few years ago).
I'll probably upgrade, and get rid of the sub (as I assume 2 speakers are easier to tune than 2.1).
The north and east walls are 6" thick, with offset studs, filled with Roxul, 2x1/2" drywall on the outside, 1x5/8" on the inside.
The south and west walls are also drywall, 5/8", studded out 1-1/2" over concrete foundation. Minimal insulation.
The ceiling is 1/2" drywall, 8" joists, around 16" oc, running east-west. 7'-4" high. Some Roxul toward the east side
The floor is 3/16" padded vinyl laminate, over concrete.
I ran REW, with and without the sub. There isn't much difference, other than the amplitude of the peaks/troughs.
Here's a sweep from 10-500hz, 1/12 oct smoothing.
1. brown - right with sub
2. aqua - left with sub
3. orange - right, no sub
4. blue - left, no sub
If I'm reading this right:
- peaks/troughs 25-70hz
- left peak/trough 110-130hz
- trough 210hz
- right peak 230hz
Here's a 20-20k sweep, 1/12 oct smoothing:
1. brown - right with sub
2. blue - left with sub
On to the room. It's a strange shape, and I'm happy to rearrange.
Hopefully they are adequately labeled, but in general:
- 7'-4" ceiling
- 11'-8" x 13'-8", with 2 corners protruding in
- a 6" x 8" beam across the short width
- 32" x 6'-7" door, flush with interior wall
- 2'-11" x 2'-5" window, inset 9"
Budget (USD):
Monitors: $2000-$3000
Construction: $2000 materials (I can do the work myself)
As for resolving these issues, I'm happy to build bass traps or whatever is needed, but I want to be sure I'm making things better, not worse!
How to approach?
- change room orientation
- add bass traps, super chunks, re-measure, rinse/repeat
- 3D model room, to find optimal solution
- new monitors, without sub (right now I'm mostly doing electronic music, so accurate/full low-end is important)
Thanks!
(Edit - looking at monitors, and upped my budget...)
