Invert the mounting on my subs?

[MonkeyBone 10+ year member]

I am in the final planning stages for my new build and had a question. I have a custom made sealed enclosure for two 12" subs. There are two chambers. The box is made out of 3/4" MDF. For increased strength I fiber glassed the inside of each chamber with about 1/4" of thickness. Because space was at a premium and I will have only about 1.5 cubic feet of space per chamber, I was thinking about inverting the subs to give me the most free space possible. I also like the look of it, the subs structure and huge magnets are sexy as hell //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif

Is there any loss of sound quality inverting the subs? It sould give me much more volume in each chamber if I do. This is a SQ build which is why I went with the sealed enclosures in the first place.

Power is not an issue because I will be running TWO Kicker zx1500.1 amps going to the two 12" Hypnotic subs.

As always I value any input you have on this subject.

you didn't ask why, you asked if it would hurt SQ...

At least you can tell me "NO" to which question....LOL

Is there a loss of sound quality?

or

should I invert my subs?

Come on throw the Monkey a Bone here....LOL

Okay it hurts sound quality. Why is that exactly?

EDIT: Oh wait...no to hurting sound quality...that's a good thing. Sorry I'm a dyslexic goofball....LOL

YES you can invert the subs because NO it will not make any difference for SQ. the difference will be in usable enclosure volume as the sub will not remove displacement from the enclosure

Very COOL, I'm going to mount them that way then. Should make a great visual impact!!!

Thanks for your input...wait that sounded a little gay....LOL

If the speakers are inverted and mounted close to you (in very few installations, but it was the case in my single cab truck) you will probably get some motor noise, or tinsel lead slap. I doubt it would be enough to bother you or really hurt SQ, but it may be noticeable enough to make you want to run them the other way.

You can always try both ways and see what you like best.

One more question on inversion in a sealed enclosure. Do you put any kind of filler in the chamber or leave it bare?

I see you guys building speakers on here and I never see any poly fill used at all. Although 95% of the enclosures on here appear to be ported.

I've build home speakers and always use some kind of dampening...

filler will simulate a larger enclosure. It is not used as much in ca because most of us have enough space for the box size we want.

I only use filler(polyfill) when i'm fine-tuning a sealed enclosure.

I think I will use some polyfill in the chambers because of the lack of space. The chambers started out as 1.7CF but is more likely 1.5 now because of the fiberglass.

So combining the fill, and inverting the subs I think it will be an improvement on the sound because of the limited space. Besides I always thought inverted subs looked cool as hell.

Thanks again for your help in answering my questions. Can't wait to get this build started ;-)
