Posted April 19, 201411 yr 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?
April 19, 201411 yr BTL cut sheets on this site are in the given range for the SP4, I dont see why they wouldnt work just fine.
April 19, 201411 yr Author btl it is, i couldnt find anything confirming that so just wanted to check.
