I'm bout to make the switch from ported to sealed. Most of the comments I have seen say to put in in a bigger sealed box then what JL calls for. How much bigger?2.0cf? more? Thanks for any advice!


I have a JBL BP1200.1 powering it. I am switching from ported because I want more detail on the low bass guitar notes, and I also want something different.

so after a little research, I found that a 2.5cf box gives a qtc of .707...can someone confirm this for me? Thank you!

i had one in a pro wedge box, witch was sealed. i hated it. had good output, but muddy as hell on the double bass. i think it was 2 ft^3 IIRC.

What would you guys do then? Keep in mind my goal here is to get it sounding the best it possibly can. I want to have punch up top for rock music.

I've had it in a JL spec ported box for 3 years and I want something new. I listen to 80% rock 20%rap


I also would like to save some trunk space so sealed does appeal to me.

honest opinon. if you wanted to stay with JL, do the w6v2. my single 12 in 1.75 ft^3 had amazing SQ. there are also other subs out there that would do better than teh w7 for SQ.

I'm not switching subs. I just want to get my dub 7 sounding the best it possibly can. I'm open to bandpass too but I've never built one before and wouldn't know the 1st thing about desiging the plans for one and I don't want to pay someone for plans.


Again, output doesn't matter. I'm not like the other 90% of this board. I am moving past my basshead days. I want my **** to sound good, not to just be loud.


Keep the advice coming!

I should mention the car is a 2000 civic coupe so I have limited trunk space. My old Jl spec ported wouldn't fit from my old car.

That box is already in the trash anyways. So as of now I have no box.

Why are you guys so against sealed? I would think with all that displacement its asking to be put in a sealed box?

I didn't mean to say against all sealed boxes...just my application...


And 4.5cubes is out of the question. I don't wanna stuff that in my trunk



How big would a bandpass be?

i love sealed boxes. 90% of the ones i've owned were sealed. however, this sub hates sealed. thats why i suggested something else. trust me, i tryed, and it sounded like ***.

I had the same set up u wanted but I changed it to the set up you just got rid of ahahah thats funny but yeah bro the bass sounds way cleaner and deeper sealed but I wanted the extra boom so i ported it and made the port trough the arm rest.:D

What size sealed did you have?

This is funny I have one person that says it sounds cleaner and others that say it sounds like *** in a sealed box. I appreciate all the feedback and quick responses keep them coming.

So you haven't heard it in any other sealed boxes?

here is an idea......


make a box about 2 cubes sealed. then let us know how it sounds.



when you realize a w7 sealed sounds like grandma farting then you will come back and give max dims of your trunk so we can help you get a design that will fit and sound nice ported.

capice?

great advice. I'll get right on it. I don't want the exxagerated low end that comes with a low tuned ported setup.

Anyone else willing to offer there .02 on sealed dub7s?

IT DOES! i did a blowthrough for my buddy's silverado! had two w7's each in 4.5 cubes at ~30hz after box rise and ZOMG! It hurt haha
