Hi Walt,

Could you send me screenshots like all modelling parameter, SPL vs Frequency and Xcursion vs Frequency plots made with AJhorn for 4 cabinets on the floor?
It would be very interresting for me....

Thanks,

Tamas

The modelling of the frontchamber is critical. If you use a large value excursion at 30Hz goes up. I think the horns starts right in between the two drivers so I used a small volume of 6 litres in my simulation. If I use 24 litres I also get around 15-16mm.

Best regards,

Walt

I think in the case of your V3 horn and my 12 Pi horn, increased excursion is related to their increased bass output.
