  1. Updated Page Methodology: How we research and verify Enclosure designer: overlong ports bend upwards with a 90° elbow; the rear-chamber port in a bandpass ends before the magnet
  2. Updated Page Methodology: How we research and verify Enclosure designer: window braces in bandpass enclosures too (per chamber), longitudinal braces in horns and TL
  3. Updated Page Methodology: How we research and verify Enclosure designer: fixed enclosures and horn rear chambers that were shallower than the driver; check for room for the magnet added
  4. Updated Page Methodology: How we research and verify Enclosure designer: fixed the enclosure volume with port tubes (too little port volume subtracted); check of the build plan described
