GM seems to be able to do these ML-TLs in his sleep
I'd take him up on his offer. The couple designs of his i built turned out well.

Hi everyone,
seems I was the one GM helped doing some simulations for the W160 AL. I have built a 42" MLTQWT following his plan and am very satisfied.
The Gradient W160 AL is a quite affordable aluminium woofer with lots of resonances in the upper frequency range.

German magazine Klang+Ton recommended to just ignore the resonances and use the woofer as a fullrange driver. Those people were right. The Gradient W160 AL represents a philosophy opposite to most Fostex fullrange drivers: Bass down to 30 Hz is no issue and enough Xmax - but highs should be more refined.
