I have an Elemental 13Av.2 gathering dust in my storage. I planned to make a 4 Cu ported box for it but after reading the LLT Explained thread, I have changed direction. Do you think it will do good in a LLT box about 8 cu tuned to 15Hz? eD site says the max excursion for this is 28.75mm and can take about 1200W. I modeled it using WinIsd and it shows a peak around tuning frequency but a dip near 22Hz. Do you have other suggestions?
