|Comparison Between Closed an Ported.|
|Basic predicted response.|
|Predicted response with Baffle step loss accounted.|
|The final result with the BSC added, with the BSC being 20R and 12 mH.|
|Basta simulation of the ported box with the BSC modelled as well to match MJK's spreadsheet.|
The dilemma of practical construction will be ensure that the correct amount of stuff is placed, to reduced internal ripples and resonances but also not too much as to reduce the bass output. There will be lots of tweaking and construction sequence issues that will need to be resolved as this build progresses.
