Sharing airspace

[chrisgray]

How will two subs sound sharing airspace in a sealed enclosure. Just curious it would make glassing the box sooooo much easier. It's gonna be two L7 eights. Also how would you figure the volume? Would you just combine space, doubling the space for one, or would there be more to it than that? I've always used separate chambers. They will be in phase/mono channel. Any help would be appreciated. Thanx Much //content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif

well well, it sounds the same, and yes, u only double the recomended vol.

but lets say 1 sub got diffectted or whatever, its not workin, other sub wont be playin nicely, it will actually be some how like playin it free air (its double the VOL.)

i dont recommend that. but hey wait for other comments //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

it's no problem, just if one goes then it tends to take the other with it if you're at full volume...

under normal circumstances there's no difference.

im woundering about two 12"s in a ported box... if its better in a single chamber w/ 1 port or 2 chambers w/ 2 ports

That's not necessarily true. It will definitely see the whole volume itself, which will lower it's mechanical power handling, but that doesn't mean it's free-air.

For simplicity sake, a single chamber is definitely the way to go IMO.

However, for a sealed box, another advantage of using a dual chamber box is that the dividing wall doubles as a nice brace //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif But as Jmac said, it's fine to use the same airspace

True, thats why i used "some how" //content.invisioncic.com/y282845/emoticons/rolleyes.gif.c1fef805e9d1464d377451cd5bc18bfb.gif

Sorry, but "some how" makes no sense in that sentence.

Well then, you are doing quite well //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif English is not an easy language to learn.

That's a really vague and hard to answer question. It all depends on the sub, your goal for the "sound" of the system, etc etc. Plus, the manufacturer's "recommended enclosure" isn't always the "best" enclosure, because generally manufacturer's recommended enclosures on the smaller side because it gives a nice peak in the lower midbass/upper bass region, which is what the typical street beaters likes his bass to sound like.

I'd venture to say most companies recommend enclosures that are on the small side

You are correct. I tried typing too fast and put the wrong word //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
