Hi Guys,
Hope you are all well and i aslo hope that some one can assist me with working out the correct spec for a true SPL box. please note I will only be doing SPL with this box.
Ok so I have 18mm ply wood, 1 12inch subwoofer, 1 amplifier and 1 battery.
Here's what i'd like to do
Get a minimum of 151db's from this setup
Equipment
DD Z1a
NSB 170 12v
Targa TG301-DW
The sub specs are as follows and i could be wrong because this is taken directly from the site.
12" COMP SUBWOOFER - DUAL 1
SPECIFICATIONS Fs (free air resonance): 48.7 Hz SPL (efficiency, 1W/1M): 89 dB Nominal Inpedance: 1/2 Ω Qts (total speaker "Q"): 0.606 Qes (electrical "Q"): 0.732 Qms (mechanical "Q"): 3.517 Vas (equivalent compliance): 20.84 L Mounting Depth: 195 mm Mounting Hole Diameter: 300 mm RMS (Watts): 2 x 1500W RMS
My Vehicle
Opel Corsa Lite +
Resonant Frequency 54Hz
Current Box
Box Properties
Name:
Type: Vented Box w/ Active HP Filter
Shape: Pyramid, truncated
Vb = 101.9 liters
Fb = 53.99 Hz
Fill = none
No. of Vents = 1
Vent shape = round
Vent ends = two flared
Dv = 247.9 mm
Lv = 290 mm
I would like to go slot port, i would like to increase on my number and i have already done the Big 3, deadening, and alternator upgrade.
Your help will be more than appreciated
