Good evening guys, first post for me here and I hope its not to much to ask.
As a lot of new members I’m sure, I’ve lurked around a long time.—so long I can no longer find all the info I’m searching for.
A while back I picked up some 4412s(my first experience with JBL tat wasn't a concert or a wedding) and absolutely am impressed with them.
I listen to them in the horizontal position with the ports to the inside.
They are matched up to and all Audio Research setup with an M&K sub.
That being said, they need new cabs.
So before I undertake the challenge, I have a round of questions I feel should be run by the experts here first—I’ve spent at least two weeks researching, so if a question has been answered here, please excuse me as my key words may have not been correct.
1. My first query involves confusion with regards to the cabinet volume.
I’ve found that the 4412 and 120Ti share almost the same cabinet volume.
The free speaker software I’ve plugged the JBL T/S Parameters into (parameters from the JBL archive and similar numbers from a post I read on here) for the 128H, show a 1.7ish ft^3 enclosure and the JBL archive calls out an even larger enclosure at 2.5ft^3 for this woofer.
Both enclosures are larger than what is used in the 4412 and 120Ti.
Is there a reason for the smaller enclosure of the 4412 and 120Ti than JBL recommends?
In the groups opinion, if I went to a larger enclosure volume, would there be a conflict with reusing the oval JBL port from the 4412?
2. My second.
I have ZERO problems with the horizontal design of the 4412—I actually kind of like the look—but out of curiosity, if I changed midrange and tweeter alignment to vertical, as in the T120Ti, does the crossover design need modification?
To best find an answer to this, I’ve used the 4410 for a research model as it was designed both horizontal like the 4412 and vertical like the 120Ti.
I can't completely confirm the crossover is the same for both configurations of the 4410, but if they are the same, am I then wrong to assume it’s a relatively safe bet the 4412 can have the woofer, midrange and tweeter aligned similarly as the 120Ti?
I hope this all makes sense to you guys, and appreciate any feedback.
I wish I could reciprocate, but unless this turns into a finish carpentry forum, I’m a student here.
