Don't tell Thomas
but I am still wrestling with the problem of deciding whether my IB driver's Fs is as claimed.
My response curves seem to show a trough at the claimed Fs.
Thomas, who is far wiser and vastly more learned than I, has dismissed this trough as coincidence. He may be right. Though interestingly, others claim to see a trough at Fs in their own IB's response.
It has occured to me that an IB should show a system resonance peak in the
impedance curve close to Fs. Sadly there is no impedance button on REW's magnificently furnished dashboard.
So can REW prove (or disprove) Fs conclusively for an
IB driver in some other way?
Given the lack of compression from such a large enclosure shouldn't Fs ~= Fc? (for any driver mounted in an IB)
Is there some clue to Fs or Fc hidden in the graphs available from an REW analysis?
Thankyou for your interest.
