Wonks wrote:Just done my normal (by now) mic relative frequency comparison of the Stag SDM50 against my SM58. (I don't have a proper test rig, so this is just pink noise through a single monitor at roughly 6" away and equidistant from both drivers, with all the inherent frequency bumps and dips associated with such a method).
The SM58 trace is in black, the Stagg SDM50 in red. I've adjusted the levels so that they have (as close as I could get) the same relative dB value at 1kHz.
You can easily see that the Stagg's got a lot more bass-end than the SM58, and that the upper mids as well as the treble are boosted by 3-4dB compared to the SM58. The bass end will be further boosted by the proximity effect when singing/speaking right into the grille.
So you should be able to tell why the Stagg's so bassy, and with those very boosted upper mids, you aren't going to get a natural sounding voice at all. If the response was flatter from 1.5kHz upwards, then you could probably make it work with a lot of bass cut. The extended high-frequency response (compared to an SM58) could then be very useful, especially with a female voice. But all that extra boosting (or alternatively, a lack of low- and centre-mids) just makes it too much hard work to bother with it. There are better (if not perfect) mics out there for similar money.
On the other hand, with the boosted bass and upper-mids/treble, it would be worth trying it as kick drum mic, as its overall frequency response is broadly similar to an Audix D6.
I'm not going to get a chance to do that for quite a while though.
Some very insightful information and excellent work
Thanks for all the help on this topic. looking forward to trying out a few other mics in the near future!
