Hi scott! 🙂
No I have not.
The horn is to long to position it in correct phase with the bass drivers.
It is now playing 1,5 wavelength behind as I remember, reverse polarity.
Some time since I worked with this but I think it was something like that.

Thnx platan 🙂
It`s here for you guys to copy and make better!
Don`t have to be JBL.
Altec/GPA, 18sound, TAD, BMS, and so on.
A lot of manufacturers.
Mabye switch the 2220 with an coax?
Maybe a multicell horn on top? 🙂
JBL 2384.
JMLC, tractrix.....

did you try the smaller tweeter firing backwards?
does the OB to horn transition ever bother you?

Hello Zmyrna! 🙂
Have tought about backfiring tweeter, have 2402 and 2405, but not got that far yet.
Will maybe bring some more air into the treble....
OB and horn I think go well together as both bring directivity.
Less reflection from sidewalls etc.
Have some reflection issue from left speaker as it stands close to side wall.
Should be positioned about 1m from sidewall.
But can`t put elsewhere so must live with it.

Maybe the speaker is not so directive in the 200-700 region.
Can see if I can measure off axis responce some day.
Dipole peak is just under 200hz on these speakers.

Try some sound absorption on the sidewalls to your preference maybe. Might help
Very nice project, I would still use the mini DSP for bass eq and delay. Cats know what is good for them.

Thnx both of you 🙂
Zen:
I`m not a designer. but I try 🙂
I learned from nice guy in Norway about using Golden Ratio when designing speakers.
The number you want to know is 1.6
Golden ratio - Wikipedia
So when putting together the front baffle, it is 80cm wide and 130 high.
80 x 1,6 = 128
so almost golden ratio.
Use this when designing loudspeakers and it will look kind of nicer 🙂
jacq:
It is no problem using DSP on this.
Bass must be delayed, also tweeter must be delayed.
but...I didn´t want to go there this time...yet 🙂
I´m not an anti DSP guy if you think so.
DSP is a very nice tool to get some things better.
You mention EQ, you think to get it a bit more correct/flet frq. responce or to get lower bass?

Oh! Reflection!
This is in our living room, cant put absorption on the window to the left.
right wall si ok, to far away.

Having OB woofers against the side wall is no problem, it supports the bass
Yes, but there is drawback in the middle range with reflections.
Choose your compromise, there is always something..

Yep, one reason I have U-frames for my woofers, and separate baffle for my wideband, two-way makes it simpler to optimise position.
Thats nice! 🙂
If I had space for it could have put the 2220 in midbass horn.
Maybe something like picture in post #36 here:
My DIY Horn setup
Have two extra 2226.
But for the time being will stay as is I think.
