Port lengths for 2-chamber 2-port bandpass

[Thawach]

i try win isd get the respond freq. the cone i simulate at 40 w rms. the port i use 2 ports

Okay, just for comparison, this is the response curve I get. The difference is, I chose the tuning frequencies not for a flat response but for minimum cone movement over the range of frequencies covered. The cone excursion graph in the earlier post is for the speaker equalised to flat response and 100 watts drive.

That is to say, minimum cone movement over the range of frequencies covered, when the speaker electronically equalised for flat response.
