The same port we use in our Mercury speaker kits.
Specs (refer to attached image):
- X: 165 mm
- Y: 26,33 mm
- Z: 35 mm
- H: min. 49,05 mm / max. 49,35 mm
- Weight: 26 grams
The tapered design means this will not perform exactly as a 35mm port, 165mm (it will act as a smaller port). The port will need to be cut to suit our Mercury enclosure tuning.
