Sometimes my KM184's sound overly bassy and even a bit boomy. Running KM184s> V3 > digi > HDP2, almost always run ORTF 110deg, 17cm.
I'm wondering if there's a problem with my ORTF setup. When using a riser, how do you measure the 17cm ?
I know ORTF is 17cm, 110deg. Ideally (or necessarily) with the mics on the same horizontal plane (HP). The KM184's can't be on the same HP because the ends meet, so ORTF is an approximation at best with 1 mic crossed over the top of the other. A riser is involved to achieve the desired height to get the top mic over the bottom mic to get the 110deg.
If looking at the mics from the top, they'd be at 110deg, and *if* they were on the same HP, they'd be 17cm apart. Imagine using a clear hard flat plastic template with markings for ORTF - placed over over the mics and parallel to the floor (assuming a flat surface), you see if you're set up right. This is how I set my mics up.
But, since one mic is higher, the distance btw capsules must be >17cm if you measure the distance with a string or directly from center of the cap to the center of the other. I'm wondering if this is a problem.
Do you measure 17cm from cap to cap or (Line B below) as if the mics are on the same horizontal plane (line A below) ?
In the picture below, B is greater than A.
