Not sure if this is the right place for this but I figure mods can move it around if need be.

I have a lot of ideas, some of them good, most of them probably bad, and I'm not entirely sure where this idea of mine lies. I was happy with the results so I thought I'd share.

I'm a musician/mix engineer/whatever you call it these days and thusly I spend quite a bit of time sitting in the near field in front of some monitors. One thing that always bugged me about these setups is that you can spend as much as you want on treatment and dial in the best corrective EQ you can, place the speakers perfectly, etc... Then you often end up putting a big ole hard surface desk in between you and the speakers and IMO it almost entirely negates everything else one does in the space to optimize acoustics. For me subjectively I lose the phantom center entirely, the top end is pretty much all comb filtering, and don't me started on the ~150hz peak you typically run into. The whole illusion gets ruined for me and I never feel particularly confident in what I'm doing mix wise when the desk is there.

Ok, so why not just get rid of the desk you ask? Well here's the thing, I really like sitting at a desk with some weight and resistance. Sometimes you just want something to lean on, or a move obvious use, place things on like a mouse or keyboard. I tried smaller desks but that created a new problem. I have cats and they love to lay down on the desk while I'm working. They don't care how small the desk is, they're laying down, and if it's too small I lose my work surface. I went down as small as a TV dinner tray, but I noticed I didn't really care for the open area in front of me and no longer had space to place some of my production tools where I wanted them. There was a period of about 3 days where I even tried to use an acoustic treatment as the desk, that didn't last long. One spill and it's over, plus I think the cats were eyeballing it as a new litter box.

Alright I'll stop wasting your time, my solution ended up being to just removed a large portion of the center of the desk and replace it with a porous material. Spent a good bit of time brainstorming on what that center could be made of, but my first attempt ended up being simple. I just went with some pegboard that I drilled some additional holes into.

Here is the desks original top. This is just a basic Ikea desk that made for a good test bed, it's just veneer'd 3/4" MDF slab on a metal frame. I have worked on this desk for probably 12 years now, my mouse has eroded the veneers coloring.

Here's the new desk top that I came up with.

And just for good measure, some additional absorption provided by the cats blanket.

Here are some measurements.

Stock Desk Left (Blue) vs. New perforated Desk Left (Yellow) 12db smoothing. Static mic position and room has a good bit of treatment (it is a small room though). Speakers are Mechano23. Not sure why REW didn't show the labels here. Lots of improvements to be seen here. ~150hz is reduced, peaks ~400,500hz gone, the mess that is the mid range appears to be better though a new peak does show up. I'll take that over how nasty the blue chart looks above 1khz.

Right speaker, Old desk in Orange, New desk in Green. Similar improvements, not as dramatic in some areas. This side has a wall while the Left is open so it looks more ragged. Still have some work to do on this side of the room.

Also worth noting that the desk reflections can be seen in the Impulse response.

Stock Desk Top. Desk issues are seen as disturbences here.

New Desk Top, much cleaner.

Thought I'd close with some subjective impressions. I have to say I'm thrilled with the sound, I do not find the different subtle. I find lower mids are much cleaner and enveloping and the stereo imaging is much more stable with the speakers sounding much more neutral overall. I'd argue the stock desk had basically no phantom center but it's very clearly defined with the new perforated desk top. The speaker overall sounds far more neutral, was surprised to see my Left yellow graph looks like it trends really well with EIR for the Mechano23.

Thanks for reading!
 
Studios tend to have custom built angled desks, maybe this would also be an option?
Like this - but smaller:

I'm not doing this for my desktop setup, but I'm no pro, so not "critical".

I would imagine the array of knobs effectively acts as a diffuser, additionally to the angle moving reflections downwards away from the listening position, compared to a flat surface.

I did consider this and attempt it after seeing it recommended on various forums. I did not find that adding a slope to the desk helped much. The lower frequency interactions were a main focus and I think those waves wouldn't really care much about the angle of incidence.

The slope of mixing consoles probably has more to do with ergonomics than acoustics, hard if not impossible to reach/read those knobs when they're far back on a flat surface.

I think this can help with early reflections too, but not in bass, obviously.
 
I think this is a fascinating topic! When space is at a premium, it can be very hard to design rigs that look good, work well, and fit into the room we have available. Your desk looks great, and i'm glad it is helping! I also do recording/mixing in my office, which took a lot of doing. My problem was that I needed to have my 88-key midi controller slide under my desk because i didn't have two walls available.

I looked and looked, and solutions were all too big and cost multiple thousands of dollars.

I ended up having a $700 custom desk built out of maple and the keyboard/computer/rack module/ speaker/interface fits on one wall.
 
Pretty distinct and nice result here... cool! I wonder how much is due to the blanket vs. the perforations?

Blanket just absorbs the highs. Everything from I'd say 2-3khz down to ~100hz is benefited from the perforated board. Bass doesn't seem to care about it as expected. Absorbancy goes up a bit when a cat is sleeping on it ;)

Let's say the blanket works a bit, and attracts kitty absorber in medium amounts... why not turn it up to 11 and use a fluffy carpet?

@Ktacos,
Clever solution,
Have you taken any measurements directly pointing at the center of the speakers and from the center where your ears would be (horizontally)?
Would there be any differences that your ears would appreciate?;)
 
I have a similar setup to yours except that I cross the low bass over to a pair of subs. My solution to better manage desk reflection interference was to lower the monitor height while raising the desk height. This resulted in far less delay in the desk reflection, and also directed most of the desk reflected sound to reach ear level significantly past my sitting position. The improvement was quite substantial. However each room and gear is different so YMMV.
 
What would the measurements look like if you used var smoothing?

I have a table in the middle of LP and the un-EQ sound is boxy because of a 300-400Hz broad peak and sharp dips below 1KHz.
 
Nice work.

I personally found a big advantage going to a much smaller desk - I run a Zaor Solo. But I also don't need a ton of space and I don't need cat lounging space.

Agreed - my desk is as small as possible. It is just big enough to accommodate a short keyboard, mouse, cell and coffee.

I find that a 2 tiered (top tier only big enough for the 32" computer monitor) corner centered desk (designed to fit in the corner) works for me.
