I thought you would be
interested to see what I am doing - I have made some test cabinets
before in cnc, the real thing (i hate mdf , I know its sonically dead
but I use it for work a lot so its nice to work with a slightly more
natural material ! ) - this may be too light it def feels it! I
will use birch ply on the real cabinets ...
I am pleased to say i
have managed to mount the port on the front - i will change the bracing
to more like your design on the real units - i have also been playing
with the depth of the cabinet +45mm deep to see if one can get a little
more bass, the built one is +45mm the other incomplete one is as drawn
in your design.
Due to budget and making these in the UK, I
am using lesser Caps but what difference there is I am not sure the HF
will be changed to a standard Cap not cross cap = ! the 5.6 mH coil
should be a p core as you designed it I was sold the wrong ones but
advised it could be corrected by using a 9.1oh resistor (vs a 10 ohm)
in the circuit to compensate for the higher dc resistance (this means
little to me.... !)
I have tried the one speaker only and am
impressed but I was worried the above change may affect the midband
balance? Also I need to dampen the cabinet properly as i am only using
some acoustic wadding presently - but i am very impressed with the low
frequency for the size of the unit and clarity warm but v detailed !
I will keep you posted ps . - despite the above my daughter thinks
it sounds better than some £1300 spendor speakers i am using !!!
