Pre-fab boxes ?
 

Would you guys recommend buying a pre-fab box from EBay at all ?

For example, here's one that Fusion makes :

Just want to know pros/cons of getting a pre-fab box versus getting one built from scratch...

I'd always recommend a custom built box over a prefab box anyday! [img]graemlins/thumb.gif[/img]

I totally agree with Chris...hehehe...All of my boxes have been custom except one and I really regret buying the pre-fab one...I just found a new isntaller, whose name I shall keep secret, cz I don't want anyone else using him! [img]graemlins/headbang.gif[/img] He knows who he is...

But, yeah custom will almost always yield better sound because they will be built to your subs specs and not generic specs..

Have fun!!

My thoughts exactly ! Thanks guys ! [img]graemlins/thumb.gif[/img]

Just make sure you are indeed getting a custom made box that IS to your woofer's specs.

It is shameful how many 'professionally made "custom" boxes' get made that are as generic in size as a pre-made [img]graemlins/cry.gif[/img]

exactly! dukk's my hero! [img]graemlins/@bow.gif[/img]

How can I make sure ..... ?

If you have the box already made, maybe measure the box and compare to the manfacturer's recommended box size..

or if you don't have the box made, make sure that it's built to the manfacturers recommended specs..

Ask questions:

Are they going to be using a computer modelling program for it? If so can you get a printout of the curve and any tuning details? If not, how exactly are they figuring the box and can you have a copy of all calculations?

What considerations are going into the box design? Did they ask your music preferences, your goals for the subwoofer system, the power you are feeding them, any possible changes in woofers you may be considering?

When I worked for a tiny independent that had 3 pretty strong chain store competitors in town I had the only software for boxes in any of them and I used to get a LOT of custom work because of it.
Now that you can find software free on the net there is no excuse for getting an underengineered design other than the store's general lack of talent and training.

I called up the store here, and I mentioned Im using Pioneer subs, and told them what model they were.

He immediately said that they require 1.25 cubic feet each for a sealed enclosure (but pioneer's website recommends 1.5 cubic feet for those subs), said that his store works a lot with those subs (check em out at http://www.chase-audio.com), and he said they've built some of the loudest cars in Canada, if not the world. I know ppl who've got their boxes done there, and I know the place is pretty reputable; theyve been around for a while.

They use a software called LEAP to design the box, but he said they didnt really need to use software. He said that it doesnt take much to determine what dimensions 1.25 cubic feet per sub require. Mentioned something about measuring the trunk and going backwards from there or something ...

Keep in mind I dont need any 'custom' work, I just need a simple MDF carpeted box made to hold my 2 12 inch pioneer 305c subs.

what do you guys think ?
