hey guys I got a speaker design where there is 9" midwoofer is working at these frequencies, I have a chance to get more of the same midwoofer giving me a total of 4 pairs, given I will make the "ideal" cabinet for the task,
will this give any sort of improvement at the low
midrange?
note that the only goal is the lower midrange improvement , any other improvement is irrelevant for this specific case.
also if the frequency its being crossed at is too high and will likely make integration problems between the midwoofers please let me know.

The answer is definitely maybe as long you don't tell more about the speaker design.
In a 2-way design, doppler distortion or IMD might be an issue when you exceed 4 mm of cone travel.
Hence, a 3-way design will improve on this. Xmax of the woofer may be reached without hearing IMD. In this case, you can use a smaller midrange which gives you more flexibility while crossing over to the tweeter.
You could also use two midwoofers making it a 2.5-way design or a 2-way MTM design.
Saying this, I don't see the point in using 4 midwoofers in each speaker. Actually, I mself have three, but one is at the backside making it a cardioid speaker.

What sort of improvement do you want to make, is it how loud, how wide, distortion, something else?
Purely looking for sound improvement, thought adding more drivers might help for reasons that might not be valid so i just kept my question as simple as possible.
designing isn't simple ,
but the question I`m asking doesn't have to be as complex, at least I hope it isnt, which is why im trying to pin point the question without going sideways 🙂
basically i just want to know if there is potential for sound quality improvement in the lower midrange doing this, and a push to the direction i should be going would be awesome as well if there is potential.
You’re not really doing yourself any favors this way. In audio, things are rarely simple, and rarely are there simple answers to simple questions. Especially if most of the context is missing. There is always some trade off, nuance or something you might have missed, not thought about or misinterpreted. That’s what this whole medium is for: give as much context to your questions as possible and let others join in answering them.
There can be an advantage with respect to:
1. lower non-linear distortion as move higher in freq. for a given volume.
2. with the right type/placement of the filter: an improvement in linearity due to floor-bounce and bounding effects for a given listening distance.
Floor/Ceiling Reflection Calculator
(..typically you target your low-pass somewhere between 300 and 400 Hz for the woofer line that is bounded/next to the floor, and make sure that your midrange is higher off of the floor.)
HOWEVER, by limiting excursion due to multiple woofers, you can loose some subjective "punch" to the result.
I have recently finished 4way speaker using tiny dayton dome, two dome upper midrangers, four cone based mid basses, and that will be on top of 15" woofer
There is thread, just for fun, called 'viral projects...'
You may find it interesting. Ask questions, if you like. Crossover is still in progress, but speakers are in use and sound great already. I use 160, 900 and 6000 Hz crossover points.
