Hello,
I’m planing to build two bass-reflex subwoofers to be used for house parties and small gigs, max 100 people. The objective for the design is something that is relatively small, lightweight, portable, and can play down to around 40Hz at the highest output possible.
My plan is to use the Faital 12HP1060 8ohm driver. Each enclosure will have Vb = 35L and will be tuned to Fb = 40Hz, port area = 145cm2, port length = 72,4cm. The two subwoofers will be powered with a Behringer NU6000 amplifier (2 x 1500W 8ohm). At max load the drivers should be within Xmax and will play down to around 40Hz. I have calculated a highpass filter at 34Hz (BW-8) to protect the driver.
I have attached a couple of 3D drawings of my suggested enclosure, which will be made from 15mm highest grade Finnish birch ply.
What do you think of this design? Is my alignment all right? What about the enclosure design? Enough bracing?
Thanks a lot for your help!
