Hey guys! I stumbled upon the Fane 12-250TC full range drivers and wanted to make a good old bass-reflex enclosure for them.

I also know I want a “boombox alignment” so I don’t have to use an equalizer as much. A good bump from 30/40 up up to 150Hz is wanted.

Tuning frequency will be 45Hz.

  • With 155L: 45Hz has +2dB, highest is 60Hz at +3.5dB and f3 is at 36,5Hz.

  • With 220-230L: 45Hz sits at +4.5dB, 50Hz even at +5dB, and f3 is still 36Hz. That is pretty much +2.5dB down low across the board.

Here’s a WinISD-screenshot for visualization

Will the +2-3db down low be noticeable?
