i have a pair of sealed-type boxes: 24cm x 24cm x 46cm (internal dimensions)
and width of mdf is 18mm.
Speaker fitted on a 24cm x 46cm face.
By measuring current at diff frequencies, lowest current gave the equivalent resonance of speaker in box.
The current was minimum at 65Hz(resonance freq.) and for frequencies above that, current decrements were very little.

All i need is advice on modifying box(port, stuffing, etc.) to get the resonance at 55Hz.
