Описание
This box for this woofer I optimised to have acceptable group delay down to 20 Hz which is compact. In other aspects it performs suprisingly good in simulations (graphs). So, if DD not lies about TS parameters, in my opinion it is really possible that this is the best 6 - 6.5 inch car woofer ever made, because it performs like on graphs in a box like this :)

Описание
This is a relatively compact peaky 4th order bandpass box for this woofer (I used stock parameters from local DB) which I optimised firstly: to have F3high=60Hz, secondary: to have just less group delay than the actual frequency's time in miliseconds (approx. 2x the level of the dashed line), after these two: ideal RMS power handling down to 10Hz, reach but not overpass Xmax, low vent air velocity. In transfer function at 51Hz/12dB cabin gain holds the "+" from 10 up to 73Hz and the peak is around 42-43Hz.
