karlson3 Posted March 12, 2019 Share Posted March 12, 2019 here's a small horn (23" by 23" mouth) in 2 Pi with JBL M151 spec (i've several of those from the old "tent sale") - Will the on-axis SPL measure as so ? - or will there be somewhat less rise in on axis SPL in practice? The light trace is the predicted power response. in my small horn collection, I have a folded midbass horn which runs a Community 12- when asking "RCA-Fan" whether it would go higher with a 12pe32, he said 12pe32 would just tilt the response upwards. (the throat geometry is the main reason it would not go "higher" but one doesn't want to use midbass horn into beaming and rough areas anyhow) Quote Link to comment Share on other sites More sharing options...
