With the cost of the 4080 box shooting through the roof, here is another alternative on ebay that is about half the price. It has around the exact amount of space as the 4080 does for sealed enclosures.

It is 150$ for 2 enclosures... what do you all think?

TIL?: This is an alternative to the 4080 Subwoofer box that we all know as "compact" for our G35's sub enclosure.

 

Put em in the middle of the rear seats like the GTRs lol $$$$ I know ha
They look decent though man

 

If you have a mesh grille, not much trunk space is lost. I wish I could have found this before I indulged on a sub and 4080 .

 

The whole purpose of the 4080 box is to leave most of the trunk space functional. I don't really think you can compare these to the 4080's because these take up a lot of space. I know I have a sedan, but with my 4080 I can still fit my golf clubs in the trunk side to side.

 

That looks pretty good but I wouldn't trade my 4080 boxes for nuthin. Those probably sound way better than the 4080s tho.

 

Why would it sound any better? Can't beat the 4080 squeeze.

 

Bigger box should give bigger bass.

 

lol.. thats not how it works... each specific model sub calls for a different internal box volume... higher end subs actually require less space, like JL, than other brands

 

too much or too little internal volume can make or break sound quality of your sub.. you should always check your sub's recommended box size before buying a box

 

Well, for one thing, no, bigger box doesn't equal bigger bass. And a second thing - those boxes list .75 cubic feet of space per box, while the 4080 10" coupe/sedan box is .8 cubic feet.

I don't think you can really compare these to the 4080 boxes. I'd still take the design of the 4080 over these. By putting the sub in the corner, all sound will be projected towards the interior of the vehicle, while those seem to be more aimed at the trunk lid. Plus, if you live in a damp climate, there's no chance of the fiberglass of the 4080 box rotting like MDF can.

For something that takes up as much trunk space as these, (but for a bit more money) you could get a custom ported box, which definitely would sound better than either.

 

That's fair, how would I get a custom ported box for that value though...? Pre-built for the sub?

 

Just an fyi, ported boxes are only good for an extra ~3db... sealed boxes have better sound quality, tighter and cleaner bass

 

The wicked c.a.s. magic box is really good also

I'm no expert, but I did make some wicked home speaker enclosures for 15 inch subs a while back. The book I referenced said that the best sound came not only from having the correct volume and porting for the speakers going into the enclosure, but also the right ratio of length to width to height. I don't know if this is true or not, but if that's the case then the corner units made to sit in front of our taillights, although taking advantage of that space the best, may not actually sound the best. Custom fiberglass enclosures aren't that hard to make if you want to have them fit perfectly into a space, but calculating the volume gets a little tricky when working with odd shapes. You just line the area with layers of duct tape that won't absorb the fiberglass, mix your resin and hardener and run strips of cotton cloth through it and put it on your taped area. Have an MDF board with your sub hole cut in it ready to incorporate into the front of the enclosure and wrap the fibreglass resin cloth around that too making it one complete unit. I've seen some people incorporate a wooden skeleton frame inside as well for a little more strength.

 

Calculating it is hard, but measuring afterwards isn't. Styrofoam peanuts!
