For those wanting to plug data into HTS enclosure volume calculator and WinISD.
The depth is shown as 23.25" to account for a double thick front baffle.
Bracing comes to around 300 cu/in using LTD's design. Could be less if dowels are used - not a big difference on volume.
The port volume accounts for both the vent AND the .75 panel to build the vent.
Port width is 24" accounting for the two slot braces (.75" each)
As usual, LTD is spot on - comes to a 20hz tune. WinISD shows the vent as being 50" long, but LTD'd design accounts for a 20% correction factor. So vent will be about 40"long. 1st port resonance will be around 169hz.
So all in all, the Martycube would net a 5.04cf enclosure.
These numbers are those interested in graphing on WinISD. Please see Chaluga's post for detailed build dimensions.
LTD, please correct me if I missed something.Edited by fr8doggr - 2/10/14 at 6:43am
