Fostex FE166eS-r in a Frugal Horn XL….

Hi Good Folk,

I have the chance to get a pair of the above Fostex drivers and was wondering how these would go in Frugal XLs? I’ve built this design for Diatone P610s and the set-up was wonderful. Stupid me moved them on. Anyway, are the Fostex worth pursuing and would the Frugals work well. Keen to hear for you guys. Many thanks, Chris
