box enclosure question
I just put my 2 10" mtx thunders in a custom box that i built. The
enclosure has more cubic foot space then recommended for a sealed enclosure. I was wondering what the difference would filling this extra space make and how will it affect my subs? Will the sound difference be that noticable? |

box enclosure question
How much more space are we talking about? Did you seperate the two
chambers? I say listen to it, if you like the way it sounds then leave it the way it is. If you don't like the way it sounds - then you could play around with throwing material into the box until you do... We'll all have our own opinions on this, and while there is a sort of science to it - it all boils down to how you like it. ~Mister.Lull dubbin it up wrote: I just put my 2 10" mtx thunders in a custom box that i built.

Also depending on the extra volume, making it ported could be another
option. I've had great luck porting various MTX subs, from the Road Thunders, Thunder 3000, 5000, and 8000. Brandonb Mister.Lull wrote: How much more space are we talking about?

box enclosure question
well they are double the recommended space needed for these 2 subs. I
didn't have any material at the time and i wanted to hear them so i popped them in. I figured i'd seek some advice before i decided to fill the box with some insulation. -- 2 10" mtx thunder 8000 rockford amp 501bd clarion dxz765mp "dubbin it up" wrote in message ...

Insulation such as polyfill would go the opposite way. You would want to
fill it with something that will actually block off sound, not just slow it down a bit. Think boards or bricks and whatnot. As it's double-recommended for a sealed, for all the MTX's I've owned, that's pretty much exactly in the ideal ported range. You might try that.

sorry to hijack on this thread.
you mean polyfills makes the sub box BIGGER? Bigger volume? What about sponge? "Brandonb" wrote in message ... Insulation such as polyfill would go the opposite way.

If the box has double the reccomended size then adding polyfil or pillow stuffing will make the subs think they are in a larger box, which I assume you don't want. Does the subs sound sloppy, or overly boomy? |

Increasing the box size reduces the resonant peak and lowers the frequency at the same time. I really have not used WinISD. I'll have to set it up. I really have not had any reason to vear fromn the DOS program I have been using since I bought it way back. Qbox. greg |

box enclosure question
This is my scenario. I think i made a error when calculating. I actually
have 1.7ft^3 of space in the box now. i have 2 drivers that require .67ft^3 recommended. so that comes to approx. 1.25ft^3 for both. The reason i started this post was the subs don't seem to sound right. That's why i thought filling the box my solve my problem. But i don't think that .4ft^3 will make that much difference or am i wrong??? -- 2 10" mtx thunder 8000 rockford amp 501bd clarion dxz765mp wrote in message oups.com... wrote: wrote: dubbin it up wrote: well they are double the recommended space needed for these 2 subs.

That would take up some air space. |

Hi Anti,
Polyfill sort of "fools" the driver into "seeing" a larger enclosure. I'm not sure about sponge. smiles, Jamie On 2006-07-18 03:02:40 -0700, "Antispammer" said: sorry to hijack on this thread. you mean polyfills makes the sub box BIGGER? Bigger volume? What about sponge? |
