Hi Maxo,

Why needing individual pictures, why not just hit the zoom/expand cross at the lower left corner of the thumb nail?*
Most of the picture concern the PA version that do not need to be changed, (Epa's cut list is IMO ok, Thanks Epa!) and I only added the Hi-Fi T-TQWT version(enclosed within a wide border line of light Grey color) for comparison, that besides the upper FR boundary differences uses a larger volume = +34L, has a negative tapering that should be properly damped if to achieve Hi-Fi SQ.

*The part of the picture that has the visible lowest resolution is the plot at the lower right corner is depicting:
When trading SPL from the PA variant to BW similar to the T-TQWT's FR:

An +(7-8 dB) shelving function inserted at ~33 Hz(An LT circuit can be used to manipulate the PA variant to achieve a very similar 'low end' like the showed variant 'Hi-Fi' is inherited from another box dimensioning.). Submitting a magnified picture:
