whats wrong with this enclosure???

[burzendowski 10+ year member]

i paid for this design and the designer says its a good design..//content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif... the woofer unloads really bad in this enclosure . the sub moves like crazy until over excursion with no output just air movement. this enclosure produces absolutely no bass. the sub was tested in another 1.5 40hz enclosure with no problems. this design is a 1.5 38hz.

what do you think? Ive wasted so much money on this enclosure

It's really hard to tell wtf were even looking at...first of all, what is the larger grey oval around the cutout? Second, what does the 21" stand for? Is tha like a port in the back or something? Can't really see it...

it appears the port isnt top to bottom of the box thats likly your problem

not to make it sound simply stupid but that would impeed air flow with the little pocket.

dd 1510 is what the box was made for

port is acting like a hole in the box. Its not a correct port

If the port wouldve been along the back wall and taller, or actually if it was a correct port, the location wouldve worked.

how much power are you running to it?

for a 1510 you are a little big on the size of the box.

the sub was tested in another 1.5 40hz enclosure with no problems.

So its not a power or sub problem

i was just saying that sub will do a lot better in 1 - 1.25

in a good box.

Oh i thought you were getting at the sub/power problem

Gotcha

How much you got wrapped up into that box?

Well the enclosure appears to be tuned correctly, judging by the the volume and the dimentions of the port, the enclosure is long enough for standing waves to have an impact in the bass frequencies, though this wouldn't cause a total loss of output.

Do you get bass if you completely seal the port? (stuff a towel ect in it)

then explain how aeroports work....

There is a lot of dead space though, on top of the port

If its having loading issues would a loading wall for the port help any? Also what about poly fill above the port? (I'm guessing on this one as I don't really know much about poly fill)

If the box specs are close to the sealed specs for the sub I would seal the box. Or jusr rip that carpet off and try to redesign the box by re-positioning the port.

I dunno, Cant he seal it and drop areos?
