Porch Enclosure

i want a custom box for my car with two 12" MTX, I want to know if it would be ok to have one side have a Sealed Enclosures an the other have a Ported Enclosures.
its an endeavor to have the best of both worlds, Light, clean and accurate bass response and have a flat frequency response curve & hit the ultra low bass notes you can hear down the street.

Will the two interferer with each other.
would i have to go with 4 speakers instead?

Since you won’t have any control over what frequencies go to which speaker, I don’t think trying to optimize with 2 speakers would be a good idea.
4 speakers would do what you want better, but could blow your amp if they don’t have enough impedance or you don’t use some sort of mixer.

But ultra low bass in a car is definitely very bad for your ears and future hearing because of the compression.
And it is also very annoying to others to hear you coming down the street, not to mention is it illegal in lots of places.

Cardboard, plastic or MDF/particle board?
And why?
Or, which one is the worst material for speaker enclosures?

Cardboard??
very few manufacturers use cardboard… and yes, it is not great. will it work? Sure… but for quality, fidelity sound, look elsewhere.

Then there’s plastic.
ABS plastic is widely used. Its NOT all bad - but the worst is the 1 layer, thin plastic.
Many manufacturers use plastic with actual design in mind… some just use 1 layer - which have bad resonance qualities.
So for Plastic: This depends on how it is used.

Wood:
wood is widely accepted as one of the best materials as it has just the right resonant properties… but*** design is a very important factor. - like thickness and port design, brace design, etc.
MDF: medium density fiberboard is good.
Plywood is used too - also good.
LDF: NOT so good — but with the right design, it works… and sounds close to MDF. .. I’d admit LDF can sound very very close to MDF — but*** the only reason to go with LDF is because of COST.
— so only LOW BUDGET MANUFACTURERS USE MDF.
CHEAP - SIMPLE… but Cheap is what some consumers want. So fine.

the other problem is that LDF: low density fiberboard is LIKE IKEA FURNITURE. It’ll chip, break, damage VERY VEry easily. It is not a great choice for speaker enclosures… but it is a necessary evil for budget concerns.

….

Now Best?
Aluminum.
very few companies use metal alloy or Aluminum for enclosures.
As you can imagine, it’s expensive, and requires alot of design hours to get it right.
Design has to be perfect… porting has to be perfect.

there are many PRO audio makers that use Aluminum as enclosures… but we are talking about OVER 1000$ EACH speaker.

Hope this helps!!

My hard drive has an advertised data transfer rate of 3Gb/s.

Firewire has a top speed of 800Mb/s. So does it make any sense to place a fast hard drive into an enclosure if you are looking for speed?

The 3Gb/s speed is under ideal conditions with the correct mobo and cables. Firewire 800 is slower than that, but for sustained transfers will do better than usb.

There is a new firewire 3200 coming out soon. That matches the speed of your drive. You also have to consider the speed limits of the pci bus the usb or firewire controller is connected through.

I just got a ball python today and his enclosure has two clips that keep it shut. One of them is broken and there is a very, very small space that is left open. I’ve heard that they can flatten their bodies to get through small spaces, is this true?

Again a couple of 13 year old kids answer a question they know nothing about. Even go so far as to be mildly insulting to the asker as they spew B.S. Anyway, Ball Pythons are very crafty when i comes to escaping and YES they are extremely flexible animals. They are adapted to flex and move to allow large food to be swallowed whole. Mine has escaped from spaces so small that its hard to believe and once actually damaged his scales a little bit because he squeezed so tight. It is your responsibility as a reptile owner to make sure the cage is sealed well enough that they cant escape or hurt themselves trying. (I dropped the ball on this one). As a rule, and no matter what anyone else tells you, If the snakes head can fit through the opening its body will be able to follow. I know what it sounds like because Ball Pythons are so fat but ive witnessed it first hand. Sure up your cage. Your snake likely spends a few hours a night testing it for weak points(Its a thing most Ball Pythons do).
All of this information can be found online and in a variety of good books about keeping snakes.
Most of the other answers you been given can only be found in the minds and hearts of children.

My computers memory is not that big and i would like to expand the memory and I want a external hard drive but while i was browsing websites for external hard drives i saw a external hard drive enclosure. Now what is the difference between then and why is one so much cheaper than the other? And what are their functions? Like what does it do.

Let’s say you have and older, broken computer. You could pull the internal hard drive out, and put it inside an enclosure. Now you have an external drive, and you’re recycling your old drive, which is obviously more cost effective. The "enclosure" does NOT include an actual drive. It’s just a box to put a hard drive in, and make it USB.

I’ve been watching HGTV and I notice that almost all of the homes have pool enclosures, like sunrooms enclosing their pool areas. Why?

It keeps it from getting too hot, and the one’s with a screen are great for keeping bugs, frogs, snakes, and in some areas even alligators out of your pool. Much easier to maintain.

Maybe you could help me with mine. I could use a girl’s opinion, and I think you’ll have fun answering it!

Hi, I would like to build four surround speakers for my home theater. I am sure the enclosure will need to be built to certain specifications in order to sound pleasing. What is the best guide you know of to building speaker enclosures? I would prefer a book over website, but any information is helpful.

Thank you.

The Loundspeaker Design Cookbook is suppose to be the book by which all other DIY speaker building books are rated…Parts express is a very good site for speaker builders especially beginners Madisond is another..

Some greater flamingo enclosures in zoos never had a ceiling built. How about if the flamingos fly out and escape from the zoo? Are they trained not to escape as there are free food in zoos?

They have clipped wings. The wings are surgically cut to prevent flight. We used to do the same thing with ducks and geese on farms.

the material stuff because i was going to make my own enclosure so i can put neon around it and have it go to the beat.

Installer.com has the charcoal carpet you’re talking about. Look under "custom" tab.

i am looking for a source of information on tools of the trade for assembling electrical enclosures. i am looking for workbenches, general tools, specialty tools including how to cut the holes for fans etc. Lifting devices for heavy panels. and any other supplies anyone can think of. All input is greatly appreciated!

Look at McMaster-Carr and TechnoTools. Jensen makes very nice service kits (tools in a suitcase for field work).
