There is a quandary that I can’t resolve.
There is a hypothetical horn-loaded chanall operating for instance flat form 100Hz to 5000Hz. Presumably I need to cut this channel off at 300Hz, very sharp-with 3-4 acoustical orders, but according to the rules of the game I must not use electrically any other thing then a first order coil. Now, here is the question: how might I do it? How to truncate sound from the channel without introducing the high order filter? The solutions around making a recursively-bent horn with intention to notch-out the “sonic tail” in the resonance chambers do not offer.
If someone would be able to offer anything that moves me in this direction then a wonderful musical handouts, not available by any other mean, are available.
PS: Forgot to mention - also do not propose any DSP solutions.
