Default Tapped horn for Tang band W69-1042M

I built a tapped horn using this driver a few years back but have misplaced the hornresp file due to upgrades on my computer. I have modeled this again as I remember the line being 8-9' but I can't get a good sim with this driver without running out of xmax at low power. I seem to also remember my tuning being about 30hz and was clean until 100hz, output was fair in the110-115dB if I recall correctly. Now my issue is I like I said earlier is I can't get this driver to model well in a tapped horn and I can't for the life of me figure out why.

If I could get a little help on a modeling without issues I would be greatful, it's driving me mad. Thanks in advance.

Dunno, just running some numbers, it takes a 1 pi loading to get 110-115 dB.

Hmm, then again, it can be 'grown' from ~109 to 188 L and will sim these numbers in 2 pi.

Hmm, your specs are considerably different than what I found on the net, so curious where you found them plus need to use the same peak SPL plots for comparison purposes.

I've been curious about a dual driver T-TQWT using this driver. It may proved the extra output wanted given the limited Xmax of the driver.

I remember a good build using two 8"x12" drivers. I wish they were still available.

Hi,

Changing the suffix from m to j is the only thing that would differ besides that the drivers would be in parallel and max power lowers from ~80W to ~70W.
