Описание
I noticed that SBL's database many parameters are missing at this driver, so first, I searched them on the manufacturer's website, put in WinISD + let calculate the missing parameters, double checked using BassBox6PRO + let it calculate the missing ones, and at least these I fill in here into SBL + let calculate the missing ones. The Vb of this box I determined using WinISD for the same reason why I determined at the closed boxes at bigger P1 drivers + designed the box the same way.

Описание
I determined all driver parameters like in the closed box's project. WinISD with at some settings not gived ideal RMS power handling down to 20Hz even for closed box's Vb for port areas which just not higher than 35m/s vent air velocity in WinISD. So I designed a "max flat" box for 55Hz/12 dB cabin gain using SBL's simple model by chosing 1 of the Vb-Fb-port area combinations which were OK in WinISD + complex model giving same SPL between it's peaks like simple model at high Hzs.
