I can't speak to Dave's Mar-Ken, but It looks very hard to modify after closed up and finished.

well, if built exactly per drawings (and without nails/screws) , one could always chop/route off the bottom to resize the port slots (yes, I've modified enclosures thus) - but all in all it might be easier to build another pair of boxes

Hi

@ Dave
Thank you for reply, i will wait yours design, hope for good news
Because the back of cabinet is removable, so it's possible to workin inside

@ Bob

Thanks Bob, i will try to do like chrib said if needed
and for other project (knowing the right measure of port) will try, because the back of this cabinet it's not removable, so will be very hard to workin inside

Then you should be home free. As soon as Dave decides the correct port length, you open them up and saw, sand, file the port down to the required size.

Thank you

has been a long and complicated work for me
for this reason I prefer try to mod this rather than rebuild

Easy enuff to tune lower. To tune higher is not as straight-forward, doable in practise, but depending on the situation maybe not practical (see what we did for our Em-Ken mules to tune higher -- a lot of saw-dust was made.

Those could easily be tuned higher, even with just a drill and a big bit (but only because the back is removable).
