hi,

in my opinion VIBE is better then JL Audio .............

Thanks

carsey

Depends what you are looking for from a system.

We had Vibe for a while up north, that is one sexy looking woofer man!

mporettim

That is a beautiful looking sub right there. I'm not familiar with that brand but kevlar always looks mean

carsey

It looks lovely.

Its sitting in a nice ported 2.5cuft box now.

Rattles galore

I'm sure with that AMP your getting some good thumps in. They say for best results use MDF, the thicker the better. Then I use liqiud nails to seal the seams and dry wall screws, a little carpeting and your good to go. I also seal the seams inside and out.

carsey

18mm MDF and its stuck together with wood glue mixed with sawdust so its stronger than the actual wood itself.

Worked out sub is getting 100WRMS more than stated, as amp pushed 900WRMS at 2ohms. Sub can take it though.


Well, I was getting a bit sick of the old Vibe sub and amp so decided to go for the new SNG Audio JATT series sub for £100. Paired with a Vibe Black Box Bass 4 pushing 900WRMS at 2 ohms, this would be more than enough to give the sub the juice it needs.

Having ran the sub in a small 1.5cuft sealed box, it didnt really feel up to the job at all. So, to keep me out of boredom, designed a 2.5CuFT ported box to the manufacturer specs.




I got the wood cut by a local sawmill/timber yard. Alot easier than trying to do it yourself.

A quick mock up of the box




Began to build the box up. It was clamped tight with some sash clamps while the screws were screwed in to make it nice and airtight. It was also glued with glue.



The front hole was also cut out by my dad with a router.




Trial fit of the brace to stop box flex



Got the rest of the box screwed up and painted the port insides





Top gets screwed on




Sub was carefully moved into the car, it only goes in one way and is very tight



Wiring is a lovely mess. but there are too many amps to try and keep it tidy.




Sub is a great fit for the golf boot.


Still need to get the sub carpetted and also im wanting to test the DB that its kicking out. Shame I dont know anyone with a meter.

jaggerwild

Very nice work!
go to a local meet they will spec it out for you, usually they have summer time meets in western NY where you can get what DB you are pushing read.

How's it sound musically?

carsey

Thanks for comments.

Yeh, ill have to find a meet somewhere in the UK.

Musically, it sounds very good. But are you wanting an opinion from a bass point of view or sound quality?

Bass: with the right box, the sub really comes alive. I had it in a 1.5cuft sealed box and it only sounded a bit more lively than my sealed vibe slick 12". Put it into the ported box and oh my, the amount of bass is a lot more.

SQ: Its a very good sub for SQ aswell. It still manages to hit quick beats well too with it only being a 12". I dont really know how to review SQ for a sub though.

mporettim

Yeah, I bet that thing gets loud in that car. Especially considering cabin gain.

I guess sound quality for a sub in a car is really more a review of how well matched the enclosure and sub are.

If it doesn't sound "boomy" and there's no port noise then I would say that would be pretty good SQ.

People always talk about how "accurate" subs are but even a nice 8" sub won't sound accurate if you just listen to it by itself. I think a lot of the "accuracy" comes from how well blended the sub is with speakers. Just my .02 anyway

carsey

I agree. I cant hear any port noise from it.

lcurle

you should put a coating of fiberglass resin on the box, it will make is stronger and make sure there is no air gaps. After the resin dries your box is solid and will not break!! Then you can wrap it in fabric.

carsey

I sealed the insides with sawdust, glue and a little water mixed together.
