PD2460 Driver

Looks like this bad boy will make some noise

this is how it looks inside Jbell Stadium Horn with 3kw power
( active filtering enabled and some corrective EQ to smooth things out )

2 cabinets with a budget Inuke6000 will hit 140db

Did your simulation account for the 24" driver hanging 5.5" further into the horn and the "J" baffle is only 18.5"?

Lol....duh!!!
Noooo.... I'm not a masta blasta!!! Like u.
I just plugged the 2460 in to HR
At least give me credit for that !!😂

I'm still learning the craft
Now I can plug drivers in to existing HR models without asking for it 🥳

Still can't translate HR screens in to plywood physical models 😱

So as I saw I'm some past posts , widening the cabinet do not alter much the sim.... Is it?🫠

Surely Nd needs changed to TH as well, no?

1. The model needs to be PAR segments.

2. S1-S2 and S3-S4 should be at least half the overall diameter of the 24" driver (12.5in = 31.75cm).

3. The response should rise from 30 to 100hz in 2pi, or the midbass will be terrible.

4. The response should be close to flat when you get to 0.5pi or 4 drivers.

Nd model = transmission line enclosure and a different fold.

The pic in post#1 of the HR screen and layout was reposted from the originator thread of the stadium horn , only the power graph in the right was done by me.

Is it what?
Abbott: Oh, no, no. What is on second base.

Widening a TH cabinet using the same speaker will alter its frequency response, but not change the lower impedance/excursion minima frequency.
The Jbell Stadium Horn cabinet interior is 24" wide.
Part "J", the speaker baffle is only 18.5" deep.
The PD24603BR is 24" diameter, Sd is 2239 cm2.
The Eminence 3015LF Sd is 881 cm2.
