So here is a subwoofer design I've been working on for a while. Its a modestly sized 10" sub enclosure that should work well with several different subs.
First off, here are some pics:
The goals of this system were to get as much performance from a ported 10" sub as possible while keeping the size of the enclosure reasonable. I wanted something that would have good output to the low 20's, but had a narrow enough profile I could hide it easily. Here are the specs of the enclosure:
Net volume: 2.0 Cubic feet
Tuning: 23 Hz
Port Area: 19.7 sq
External Dimensions: 12" W x 21.25" H x 24.75" D
External Volume: 3.65 Cubic Feet
Sub drivers that should work:
JBL GTO1014 (This is what I used)
Here is what it does:
This measurement was taken at 10 feet with 6.3 volts of input power and 1/12 octave smoothing. It should be very close to a 1W/1M measurement.
If anyone would be interested in building one for themselves it takes a little over 1/2 sheet of 3/4" plywood.
The cutlist is as follows:
Sides x 2 - 21.25 x 24.75
Top/Bottom x 2 - 10.5 x 24.75
Front x 1 - 10.5 x 17.875
Front doubler x 1 - 10.5 x 17.125
Back x 1 - 10.5 x 19.75
Lower port x 1 - 10.5 x 21.375
Upper port x 1 - 10.5 x 15.375
Braces x 2 - 10.5 x 2
This is the internal layout:
The port is 1.875" tall.
Here are some pics from the construction of mine:
I didn't get a picture of it, but the inside of the box is lined with felt. I rounded over the ends of the port panels and put a 1" roundover on the port mouth.
