In the Thread: Thoughts on midbass horn approach
Post Subject: Thoughts on midbass horn approachPosted by noviygera on: 8/6/2018
I have identified a direction for my next speaker system. Whether it is a good one or not is a different topic -- I think it's a good one because I've lived with my current horn system for 10 years and have since developed an understanding of it's strengths and weaknesses and in my view the set of requirements. I think they are necessary to set basics. Again, those are the basics that I came up with, not recommended by someone. In my room and listening habits seem very reasonable.  Some may not agree but this would be another discussion. Back to my point: My requirements would require a new system and a lot of experimentation and tuning capabilities built into the new system.  First off, the midrange horn shall be Western Electric 13a with a 14 foot long horn, based on the 555 driver. 
I would like to ask your thoughts on the way I am approaching the midbass channel. Is this a reasonable way to think about design of midbass:
1.To match the footprint of the 13a horn, the midbass horn will be folded, sit on the floor, underneath 13a horn. This will elevate the 13a horn to correct ear level.
2.To have time alignment with 13a horn the midbass horn path must be about 14 feet.
3.To let midbass horn cover below 120hz.
4.To use field coil driver and to adjust the Qt if necessary, to fine tune midbass sound AFTER installation.
5.To let this midbass channel play as low as it can (while still sounding good). Below that use sealed subs if needed.

Using the list I made is possible to arrive at good performing midbass within constraints of system based on a large midrange horn that plays down to 120hz? So as to cover most of sound below 120hz.I am not sure about #4. Is this a useful thing in midbass horn?
Thank you,Gera
