JBL W12GTI...What is the perfect sealed box size?

[jet 10+ year member]

What is the recommended sealed box size for this sub? If you have this sub in a sealed box let me know the size you are using and how you like the sound.

This will be my first sealed sub and I want to do it right. I understand the driver displacement is .149. I have a fiberglass enclosure that is .95 cubic feet, is that too small for this sub?

I attempted to figure this out with winISDpro. This is my first time using that software program so I am not sure if I am using it correctly. The box that program recommends seems quite large. I came out with a figure of 1.868^3 for the sealed box size (for a qtc of 0.704).

1.868 (box) + .149 (driver displacement) = 2.017 cubic feet for the box?

2cf is kinda large but you will get good low end extension. I ran a W10GTi in 1.75cf tuned to 28hz. If you have the space, port it and tune it low. You'll love it. What amp are you gonna push it with?

Mkii

 

[Detox420 10+ year member]

Shietttt....the MKI was impressive, excellent SQ. The MKII should be even better. God...I would love to get my hand on one of the MKII. How much did it cost ya?

AMPS- PG Ti500.4 AND Ti1200.1

F SPEAKERS-JBL C608GTI

R SPEAKERS-JBL T595LIMITED

SUB- JBL 12WGTI MKII (two coming soon !!)

spec wise they are the same. i think they just changed the look of the cone for their 60th anniversary. im planning to get one when the price on their accommodation site goes back down. that looks like a good amp to run it with as these subs are extremely low distortion. im planning to get the jbl/crown bpx500.1 also

how are the c608gtis? i was thinking of getting that too but heard their midrange wasnt that good. what can you compare it with?

None of my stuff is installed yet. I have read that too about the c608gti's but I want to find out for myself...they can't be that bad could they?

So back on topic...what size sealed box for the 12wgti?
