Hey guys,
Need a bit of help here as I searched all over and cannot find any info on this X-18 ported enclosure, size is not an issue since its going into a van.. I would like to keep it 'musical' but has some 'thump' when need be, daily driven across the midwest, weekly.. I ordered a single X-18 D2, will be running at 1ohm on my IA 20.1, roughly 1800 rms, wiring and extra power all taken cared of. I used the Torres Box Calculator and came up with some # and need to see if this is something you guys think will work or not..
First the subs specs:
X 18
Fs : 20.5 Hz
Qes : 0.57
Qms : 5.61
Qts : 0.52
Le : 5.92 mH
Sd : 1140 cm^2
Vas : 237 L
BL : 24.79 NA
Mms : 470 g
Cms : 128 uM/N
Sens : 87.22 dB 1w/1m
Wattage: 1250wRM
Torres Box #'s I came up with:
GROSS VOLUME: 6.80CF
PORT VOLUME: 1.27FT
PORT AREA PER CUBE: 15.32IN
PORT AREA: 74.00IN
NET VOLUME: 4.83FT
PHYSICAL PORT LENGTH: 22.50
TUNING: 33.35
Basically, box is going to measure 40X18X20.. with one slot port.. So, question is, do you think the box is too big for 1800 rms??. If so, what size box should I use?. Any help from you guys would be great!!. Even a link if anyone knows of one.
