[QUOTE="Robert_E, post: 243735, member: 853"] Those many small rectangular ports are huge potential noise sources. What airspeed does WinISD report through them? Can you post a graph? I would rather recommend you stick the driver on one end of the tube and have bigger ports on the other. If you want to use 2 drivers rather chop the tube in half and build 2 subs. I also see you model with a larger internal volume than I used in the same tube. Are you deducting the volumes the endcaps, ports (my dual ports displace more than 70liters of the internal volume) and driver displaces? Can you post some graphs without any EQ applied? How do you intend to apply the EQ boost in practise? I haven't seen an off the shelf device that allows for PEQ with a center frequency below 20Hz. [/QUOTE]
