Interesting. Basically same mouth size I'M considering, and about 8" longer than my model.
How big is your space?
What do you use below the mid bass?
It's part of a 28 deep by 36 ft wide basement that is semi open where the main "bunker" is 15 wide 28 deep with seven foot ceiling on a concrete slab where the bunker is cinder block with windows and an door that goes outside. Like most small rooms - Pretty problematic.I added a bunch of acoustic scatters recently and the room went from over damped dry to a nice warm wet sound. The bass is deep. powerful and dead on.
I forgot to mention - I also use what I call UB couplers - they are driven by a separate amp between 60 and 100hz. they serve as a base for the compression chamber of the midbass horn. In each sealed box is four mid efficiency 8" drivers wired in parallel and coupled to the floor. They have a voltage sensitivity of around 105 db without the room gain.. What they do is add the STING to the upper bass and smooth the transition between the 15's and mid bass horns.
These are really stunning in their range.

Also not too bad in the midbass horn but roll off starting around 300 Hz

Celestion midformat cdx14-3060
I always like the small format celestion drivers so now i have the mid format driver to evaluate.
this is measured in room 1 meter in ev keele conical expo 60 degree horn. big horns - i attempt to measure at axis 15, 30, 45, and 60 degree. not so easy
and here at 30 degrees, probably what to expect at listening position
this combo is a very high end upper midrange low treble system
distortion is not too bad, real large format 4 inch drivers can be better bit this is much better than the be jbl 2435 and altecs 288, 291, 299 i have here

the 1.4 exit celestion in keele ev 60 big horn
an altec 299 1.4 exit in keele 60 - overall this is lower distortion than the celestion by nearly 10 db
what i am listening to the d405ti 2 inch exit in jbl 2386 - in my system to 5k - very low distortion

Hi POOH!
Compliment me for the good work done, and I would ask for advice considering her great experience in the subject.
I'm studying the possibility of building a two-way compact home speaker system, I've read the coupled Faitalpro HF146 driver + 18sound XT1464 horn, i would use it for the high cut at 5 / 800Hz 6db / oct. I would like to realize a minimal but effective system, above all in terms of quality rather than high sound pressure, sacrificing a bit to the extreme band. I want to point out that my dedicated end will be a jlh 15W / 8ohm class A SS. I would like his advice in the subject. Thank you in advance and cordially greeted.

Can you do the graphs at 5 Db increments please, I thought it is normal practice. don't mean to sound rude but for us newbies it is a bit distorting and the bigger the scale the better it looks. We all need a refrence to what is good n bad
I didn't take those measurements for you, I took them for my own - when you do your own measurements you will take them for your own purpose i suppose
JBL 2384 HORN - 2435BE VS 2450SL AQUAPLAS
2435 BE DRIVER
2450 SL AQUAPLAS COATED
I think the 2450sl might need a listen 🙄

dauumm... i should hang around here more. im horn now from >420hz
for new system i would like to go two octaves down.
as starter and compact size there was 135 hz Mid Bass Horn - The Paper Horn by Inlow Sound with that cheap 8pe21 innit. i dont know if i want to use that on midbass cause my midrange driver is more "badass" than this 8pe21.
You could throw me advice option for 100-500hz if you have something on your mind

hello, what do you mean your midrange driver is more badass than the 8pe21
what is the reason to upgrade what bass system. what is the speaker system
if you use low midrange upper bass horn do you have bass and deep bass that can keep up

Its custom precision devices 8" made to funktion one. They run it 250-5600hz then cross it to 1" cd
So looking horn underneath that
Now i run sealed low and low mid
Why im changing? I dont want to get stuck on same speakers and 250-5somthingk sounds interesting

An eight inch driver and crossover it now at 250 and 5600 and it's front horn loaded ? That's pretty amazing bandwidth. Do you have a drawing or a link to the driver / phase plug?
