Relatively compact closed box which will sound great, have ideal RMS power handling down to 10 Hz. In simulations I used 60 Hz / 12 dB cabin gain.

In this project I designed a relatively compact vented box for this woofer to have down to 20 (19) Hz ideal RMS power handling, low vent air velocity, and as horisontal amp. resp. and SPL curves as it is possible at 60 Hz / 12 dB cabin gain. This gived a box with acceptable group delay at every frequency, and the port is on the same side of the box like the woofer.

I created this project as an example that it is possible to build a vented box for this woofer which have outer dimensions which allows it to install inside any normal car's trunk, and have ideal RMS power handling down to 10 Hz + sounds good. For simulation I used cabin gain 60 Hz / 12 dB.

I creared this project as a comparison-project for my previous 3 projects for this woofer. Red - closed box with ideal RMS power handling down to 10 Hz, green - vented box with ideal power handling down to 10 Hz, blue - vented box with ideal power handling down to 20 Hz. In simulations I used 60 Hz / 12 dB cabin gain. On 3D is the box with the blue lines on Graphs.
