^ agreed... which is why you should run your speakers in winisd or a similar program...

i have yet to find a speaker that i have put in ported or sealed exclosures that didnt benefit over an i/b application, and ive done lots

btw, nice sig theboy

Does this need to be rehashed? again?

Nobody wins.


The driver in question will perform differently in an enclosure than in a door cavity. One has to ask themselves if the difference will be audible with consideration of the rest of the overall system and worth the extra effort.

it has been my experience when playing with foam speaker baffles (basically a small pod) that the volume was too small and all but eliminated any bass output from the speaker.

that said I'm sure an appropriately sized sealed enclosure would help the speaker out, I know Cerwin vega recomended a 400 cubic inch( about .25 cubic ft) sealed enclosure for the 6" midbass in my IT6.02 component set , so the enclosure would need to be fairly large

just deadening and sealing up the door really well does seem to make a pretty good difference, I don't know if it would be worth the trouble, or even possible, to acually build a proper sealed enclosure in the door

try making an appropriately sized box square test box for the woofer and see how much better they perform in the box as compared to the door and then decide if it's worth the trouble

We sould leave it at that.......but we wont will we!!!!!!

The Corrado isn't a Buick. The doors aren't too big to go thru the effort of building enclosures in this case imo. Unless you're going all out like defro's beauty ported door enclosures that is.
I tried small enclosed pods about the size you're talking about once and it sounded terrible. Weren't large enough.
I would seal the doors up nice and deaden behind the driver on the outer skin and go with that.

Just to keep this going... [img]tongue.gif[/img]

sounded terrible....... or just didnt sound typical like every other ib mounted driver???

the only way building an enclosure for your midrange/midbass works is if the correct amount of volume can be attained otherwise i/b is the better way to go. i have yet to test one speaker that didnt have audible improvements in either a sealed or vented box over i/b as long as the volumes is correct. some will say that its not worth the time for the gains and things like that
(ususally those who have never heard or tried it predictably enough), in some cars its just not practical or feasable, but if in your car this can be done, you should at least try it, you likley wont be disappointed

Do give your speaker a good run through some decent enclosure design software. Typically, if you find the speaker has a high Qts, it was intended for the quasi-infinite baffle environment provided by a car's door.

No matter what the designer intended, you can clearly chart the differences (and benefits) of a well-designed enclosure. Eliminating the random nature of a door's air volume has been discussed at length, and for a very good reason;
random science yields random results.

^ well put

try different things and then learn from them ;)
