Custom Sub

ZippyTs · 22nd January 2010, 08:18 PM

So I have been planing on making a new box for my sub. It is a Diamond Audio Macdaddy motor and basket, and other for the cone, spider, and such. It is a D4 running at 2ohm. I just tested it and got the T/s for it, and would like to know what you all think would be a good box design for it. It is currently in a 1.16 ft3 sealed box, and seems a bit lacking. Running off a Diamond Audio D5 600.1 amp. it is a 12" speaker

T/s are:
F(s) 26.24 Hz
Q(ts) .4028
Q(es) .4464
Q(ms) 4.124
V(as) 3.414 ft^3
C(ms) .17 mm/N
R(e) 2.009 Ohms
Z(max) 20.57 Ohms
Z(min)2.009 Ohms
Xmax 14.8 mm
S(D) .06277 m^2
n(0) 0.3731%
SPL 87.82 db 1W/1m
L(e) 2.015 mH
BL 12.5 N/Amp
M(ms) 210.6 g
Piston diameter 11.13 in
Driver disp 0.176 ft^3

The speaker was measured with the Daton WT3 unit. I would like to know if I should keep the box I have, or change size or box type. I would like to keep the size of the box down as it is going into a ford focus. I will be making the box myself and such. I want to do it this weekend if possible.
Thanks
Zippy

Describe what you mean by "lacking" . Is the output not what you were expecting? Or is it something else?

yes, the output was not what i was expecting

Plenty of piston movement, but not very loud

I was playing in winISD and came up with this

looks good. you could gain a little more output and still go reasonably low tuned to around 35 hz but what you have should do just fine and probably retain a but more sq

Great, I will be trying that setup then. My amp has a subsonic filter in it should I tune that to the f(s)?
