3D model description

I created this tool for making customized speaker enclosures to suit any driver. There is a fully parameterized Fusion 360 file and STEP files.

I made stl's for example enclosure sizes of 1, 2 and 3 liters, with properly sized bass reflex ports for 3 popular drivers.

If you use the Fusion 360 archive, when you change parameters it will generate all the required components: the enclosure, the port, and multiple versions of the front and real panels. The panels include versions with holes for screw mounting and versions for gluing. The enclosure has 6 holes on each side for M3 heat-set inserts, using these is optional, you can just glue the panels in place if you prefer. You can use wood in place of plastic for the front and back panels, if you want to save print time, or you prefer the look.

The reflex port is flared at both ends, and should be assembled according to the image above.

The three examples are created for these widely available Dayton Audio drivers: 1 liter DMA70-4 (Value), 2 liter ND91-4 (High performance), 3 liter TCP115-4 (Value). The WinISD curves are in the image above, and the WinISD models are attached in a zip file.

If you're looking for a ready-to-go tested speaker design, check out my existing designs here: https://www.thingiverse.com/thing:3384017

The three example enclosures are as follows:

Dayton Audio DMA70-4
Volume l lt (0.95 adjusted)
Tuning frequency 95Hz
Port Diameter 20mm
Port Length (including flare) 95mm
Baffle Cutout 65mm
Hole Diameter 84.1mm

Dayton Audio ND91-4
Volume 2 lt (1.95 adjusted)
Tuning frequency 69Hz
Port Diameter 20mm
Port Length (including flare) 87mm
Baffle Cutout 79mm (rear mount)
Hole Diameter 93mm

Dayton Audio TCP115-4
Volume 3 lt (2.85 adjusted)
Tuning frequency 56Hz
Port Diameter 25mm
Port Length (including flare) 146mm
Baffle Cutout 102
Hole Diameter 108

Printing and Assembly:
I suggest at least 3 perimeters and 30% infill
Gorilla glue will work for gluing the front and rear faces

Optional components:
12x M3 heat-set inserts
6x M3x12mm screws for rear face
6x M3x10mm screws for front face
4x M3x10mm screws for driver
2x Speaker terminal binding posts (5.2mm hole)
