Description
This is RMS-power optimised vented box for this woofer. I simulated RMS-power optimised closed box too for comparison. As you can see on the graphs, this vented box at 20 Hz and higher frequencies is louder at low frequencies + cone displacement and power handling is similar + sounds not so accurate but still acceptable + have acceptable vent air velocity. This vented box is not thin (compact) like the closed boxes in my previous projects below.

Description
This is RMS-power optimised closed box for this woofer. In woofer's original datasheet the peak power is 600 Watts, but on some websites it is 900 Watts - this is the reason why I optimised this box for 300 Watts (see the graphs). The box itself is thin, and the largest outer dimension is less than 900 mm - to not take up too much space in a small car's tight trunk.

Description
In this project I simulated 6 different Vbs of closed boxes for this woofer. Red: 70.8L - largest recomended from woofer's original datasheet, green: 36.5L - RMS power optimised, blue: 28.32L recomended from woofer's original datasheet, orange: 26.97L - biggest Vb that reaches 0 dB at 10 Hz in amp. resp using stock SBL cabin gain, magenta: 26.49L - smallest Vb that reaches 0 dB at 10 Hz in amp. resp using stock SBL cabin gain, cyan: 21.24L (on 3D) - smallest recomended from woofer's original datasheet.
