Hi guys, i've been told that a Subwoofer that is in a Sealed "Hacth" Enclosure will perform a lot much Better than a Subwoofer that is in a Sealed "Square" Enclosure, is that true? how is the performance? they said me that the one in the Hatched will perform a lot much better because the frequency will not reflect so that it cause an cancellation compare with a Square one, So, is this 2 true? what's the difference between these two Enclosures?, Thanks Guys.

That's a lie. Whoever told you that is ill-informed. Enclosure-related standing waves have next to no effect on subwoofer performance.

Also a little bit of stuffing on the back of the box would eliminate any reflection.

There is no such thing as free installation!

I personally prefer the "Hatch" box as compared to the cube. When the waves come off the backside of the cone and hit the back wall in a cube, they refect right back and hit the backside of the cone. In a hatch, you don't have that problem.

If you can HEAR, and I mean REALLY HEAR the difference, you are a superhuman (and you're gonna have to show me that you can pick out one enclosure over the other MORE than 50% of the time, in blind tests). The waves you are dealing with are FAR to long to EVER be noticeable as a reflected sound, and I GUARANTEE THAT.

If you are running full-range, you MIGHT be able to hear reflected sound difference, but anything below about 500Hz, forget it. Actually, if your box is one foot deep, that frequency is 1130Hz. So, it ain't gonna happen, my friend.

It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

I was skeptical about the standing wave issue as well with the construction of my box for my IDQ's. However upon ID's assurance and the actual sound (it is a rectangale) I haven't been able to notice any issues what so ever.

And if there is any such problems, I am sure poly fill would do the trick.

Not only can you not hear it, you can't even measure it. Enclosure geometry (other than physical size) has no effect on subwoofer frequencies woofer performance.
