Hi all,
I'm looking to see if it's possible to simulate in Horn Resp two drivers with a slot loaded open baffle (both drivers in phase) and basically see if changing the slot cavity dimensions changes anything that can be seen in simulation.
Any ideas how one would approach this in Horn Resp?
Very best,

That's a tough one.
Can you do it with the multiple entry feature?
Do a straight flare and have the mouth with same CSA as the slot CSA for a length of .01cm or 1.905cm (0.75in).
I don't think I have the ME function on version 50.70. And, I just noticed I don't have HR pinned to my new work laptop's task bar!

Hey DMB, does version 50.70 have the Multiple Entry Horn Wizard?
13.13 volts = 100 watts @ 3.45 ohm.
I am assuming each driver is firing into 18.25in H x 18.25in L x 3.75in W section for a 7.5in wide tunnel.
For some reason, GRS or Parts Express is claiming a 1,234cm2 Sd, which is greater than the 18.08in diameter of the drivers.
That's why I used 2,468cm2 for 2 drivers.
Front and right side.
Back and left side.

I'm thinking of trying to simulate two GRS 12SW-4's in series, cone facing cone, in phase, in a cavity/slot that faces out to the room that is about 12 inches deep, 12 inches tall and 2.5 inches wide. This is on an open baffle (W frame folded to have a central slot).
Do you think this is something that can reasonably be examined in horn resp?

I'm still trying to figure out the basics to the Multiple Entry Horn Loudspeaker Wizard.
I'm trying to SEE the enclosure on the Schematic Diagram screen.
To me, it looks like you cannot have the drivers PARALLEL to each other.
The reason for flipping 1 of the drivers is to cancel harmonic distortion, similar to isobaric configuration. The 2 drivers are still firing in phase for combined output.
In the pic below, the left red line looks like 2 x 18's firing to the right direction.
The red circle, which should be smaller than the black circle (1,234cm Sd for 1 driver), looks like it's firing to the front or back.
That configuration is a 90* throat to mouth enclosure.
As a matter of fact, the square should be slightly bigger than the black circle.
Let me play some more. I will work with GRS 12SW-4.
If ME does not allow drivers to be positioned PARallel to each other, then we'll use the OD function.
The pic above is similar to a PPSL enclosure with an open back.
The pic below LOOKS like it could be modeled with the ME1 function.
According to the site, they are using the floor or ground as the bottom with a top panel.

Thanks! Yes, there would be a panel the same depth as the drivers' manifold. So at least 12", but more like 12 & 5/8th inches or 330mm roughly front of baffle to the back of the panels on top. A typical slot W frame with a footer and top but of course open in the back.
I'm trying to see if there's a way to simulate the differences with the slot width going from something like 2.5 inches to 6 inches and what changes with that slot width range. And then I'll build a working model and test it.
Thank you for everything you do!
Very best,
