hi oliver
the le value is guestimate.
i discused it with david mcbean.
le value rise's as frequentie drops ,and is@ <100 hz usualy ~double that of 1 khz wich is usualy stated in ts parameters.
but even @3mh still looks good.
the speaker is "looking" at a big hole ,no slot.
i moddeled it both as straight horn piece or a chamber ,and it looks pretty much the same

edit/ @olsound,with casters and handles,or straiaght like the on above?

Hi epa,

I hope you are correct. I don't have the time to mess with it right now, but when you enter something like: Ap1=906.00 / Lpt=1.80 / Atc=2000.00 (not changing Vtc) the response changes, and not for the better.
Regards,

i think we should see the ltc as the distance traveled bij the wave from speaker to exit of the chamber.
i jou look at the pic above the wave travels about 30 to 50 cm to reach the exit.
now if the opening of the chamber was in the midle distance was ~15 to25 cm,then atc would be~2000 in this case.
i asked david mcbean how to interpet the chamber.
this is how i understand the atc ,vtc,ltc works.

i,m a bit confused about the size of the wood
i just learned that 3/4 ply is actualy 23/32
its important to know the excact size.
its now moddeled with 19 mm pannels,
could you measure a pannel 1/2 and 3/4 ?

epa can you moddeled it with 18mm pannels
sorry for the confusion

hi oliver
your right at the point where the suround could hit that board we need to take out 1 cm to be safe(in case of extreme excursion).
