Some FEM simulations are in this case only interesting to see if we can use this for example for the effect of stacking and/or the effect of the folding of the horn sections. 95 (if not 99%) in this case can be done with Hornresp and in my mind you have taken my Hornresp printscreens as a starting point and did go from there (iterating between Hornresp and 3D), but I don't know if we are on the same page .

- Maybe others know what maximum ratio makes sense for a high-output (and robust) subwoofer using this driver.
- It could be the 'real' S1 value is a bit higher due to the front chamber volume.

Compare it to this, an 18" in a DSL box with a 22.5" exterior height:What do you think about compression ratio?

The high powered BC 18" can take pretty high compression ratios..

Unfortunately you have to divide your horn sections again because the first section is used for the offset part.

The frontal chamber volume of 3000cc is a rough estimate (don't know how I came up with it ), but it's wise to check/calculate that ...

If BP1Fanatic and you come to the same result, there is maybe some finetuning left, but this is what you can achieve in this size of enclosure.

The BC218 has a 30" exterior dimension, the height of S2 is 28.5".Do we know the height of S2 in the DSL enclosure?

The mouth exit areas appear to have laminated the plywood to 1.5".
