I'm studying industrial design at Wentworth Institute of Technology
in Boston. I have been given the following assignment: to design a
speaker enclosure to house a 4" woofer and a 2" diameter tweeter.
The tweeter is an Onkyo 3/8" (269-708) standard one-way driver.
The driver parameters are as follows:
Fs=4200 Hz
P-diameter = 0.375"
Sd=0.713sq.cm
Re=3.5 Ohms
Le-= 0.013Mh
Z=4 Ohms
Pe=20 watts
no=0.306%
1-W SPL=87dB
2.83-V SPL=90.59dB.

Woofer properties:
Goldwood, GS204/4S (290-370) standard one-way driver.
Driver parameters:
Fs = 138 Hz
Qms = 7.19
Vas= 0.991 Liters

Cms= 0.336 mm/N
Mms= 3.964 g
Rms= 0.478 kg/s
Xmax= 1.5mm
Xmech= 2.25mm
P-dia= 3in
Sd= 45.6 sq.cm
P-Vd= 0.00684 Liters
Qes= 2.2
Re= 3.333 Ohms
Le= 0.184 mH
Z= 4 ohms
BL= 2.282 N/A
Pe= 40 watts
Qts= 1.69
No= 0.114%
1-W SPL = 82.72 dB
2.83-V Spl = 86 dB

Box parameters:
Type" Closed Box
Vb= 4.248 Liters
QL=20
Fill = Heavy

My assignment is to design two bookshelf / desktop speakers that not
only produce quality sound but are visually appealing. Our professor
suggests we use ½" or ¾" MDF fiber board because it is dense and
good for sound applications. We are allowed to explore other materials
if we desire. This assignment is pretty open as far as materials and
box design. I'm not asking for someone to do all the work for me
with this assignment but rather provide me with some tips or possible
places I can find some information about speaker boxes. Anything you
can provide me would be most appreciated. Thanks!

If this is not the correct newsgroup to post this to if someone could
direct me to a more appropriate group I would really appreciate it.
