I want the biggest SPL from about 13hz. Subwoofer will be used only for region 13-30hz paired with velodyne spl1000 in range >30hz.
When I look at WinIsd, number 3 looks the best. Any other driver from ebay in that price?
Thanks

yes there is a huge peak in LLT and around the peak, frequency response drop off significantly.

So, which driver? I was looking for RE AUDIO MX 18 D1 and Kicker S18X2.. Any other?

they model very similiar. in LLT 13hz ported 500litres there is a huge peak at 13hz, but good spl in both cases - from 116 - 119db. i will probably choose BTL because kicker is not available on ebay now. kicker has more mms (around 800-900!?), Fi is "only" 340.. and bigger cone area, because its squared woofer
