Recommended enclosure for a small Scan-Speak driver (15M4531)
according to Hobby HiFi (German magazine):
15 liters - tuning frequency 38 Hz - BR port diameter 50 mm - length 230 mm.

What do I do about the port if I want 2 or even 4 drivers in the enclosure ( 30 & 60 liters respectively)?
Will the length stay the same and change the port volume only (2 & 4 times volume) ?????
