Does an omnidirectional moving coil mic exist which has switchable RL high pass filter?

If not it may be a pity.


Omnidirectional microphones connected to an R,L filter, see Pleiades R,L filter would immediately stand out from most microphones. Such filter may not be needed for speech but for singing it is important to reduce bass heaviness and make the vocal part shine trough the backing track.


Such filters can be found on mics such as AKG D1000 where the need also exists to compensate for the proximity effect.


But many omnidirectional microphones which sound bass heavy due to Fletcher Munson or Voice effort curves should benefit too in the quest of flat frequency response from producer's brain to listener' brain [Lowe, Morgan].


They could compete with the best condenser, ribbon, printed ribbon mics which too need such a filter.
