sp4 gen cut sheet

[ncc74656 2]

i seem to recall either FI or a member on here stating to use a Bl or BTL cut sheet for the SP4. i am getting my recone soon and want to build a plane vanilla box tuned to recommended spec to see what it sounds like. what cut sheet should be used with the SP4?

BTL cut sheets on this site are in the given range for the SP4, I dont see why they wouldnt work just fine.

You shouldn't go by BTL cut sheets..
