Do they need to be put in a seal box if place in a open Attic?

I made a box for mine--see details in my review 2/9/14. I don't think it affects sound much, and Polk claims the speakers have an "infinite baffle" design. If you make a box, you might want to put a layer of insulation on the inside to cover the drywall. I've noticed the drywall around the speaker gets cold during winter.

I would say no. I have these in my living room, dining room & basement. I have the singles in my kitchen & bedroom. They are all open. Some in insulation, most aren't. They sound is awesome. Tons of bass. I have an onkyo 626 running all of them. I even have a set of the outside speakers. I guess you could say I was so impressed With the first set I kept buying more. I would recommend them. They sound pretty great.

No. I put them in an glass jar that can be sealed tightly. They maintain their flavor that way.

I have not vacuum sealed them. I store the original bag they came in, in a freezer zip lock bag, in the freezer and they are still fresh after one month.

Yes you can and put any sealed connection you wish on there but best too order a pack to mate them with to prevent moisture causing problems later on. Hope this helps you

They are not sealed. Even if you buy in the store. Not sure why but they are fine. Amazing product for the cost.

They are not individually sealed. You need to seal the absorber each time you use one

If you get them sealed properly they are very good at keeping a good seal. There is a little plastic tool on the front that one uses to seal with. I love mine;=.

It's best to seal them in an airtight plastic bag. I also add silicon packs to the box. So far, everything has remained dry and it's been over a year.

Yes, I purchased them for long term storage since they have an air tight seal.

Sorry,it's been to long and I can't recall. I would think they should be sealed though.

I keep them in the ziplock bag they came in just make sure that it stays sealed. It wouldn't hurt to throw onther bag over the first one, the big thing is to make sure they do not dry out

Hi Bonnie. Yes they will do fine in a vacuum bag. I would put them in another ziplock bag, and just not seal it, or use an extra layer of vacumme bag for double protection from the sharp edges. I keep mine in a mason jar. The smallest size I can use and they are keeping just fine. It is also more convenient because you can open and close the jar many times and not have to seal with the machine each time or waste bags. Hope this helps. Glennis.

They are bagged, then boxed and really well-protected. There should be no problems...at least I had none.

If you can purchase an insulated box from them. I ordered mine when the weather was warmer and they were sent open to the air in a net bag. Worked fine then but I am afraid they would freeze now. It took about 5 days to receive.

They are sealed in foil wrap so they should be fairly air tight . . . I'm been using the same box for several months with no problems at all ... not sure what you mean by "years" . . .

I refrigerate them in the bag they came in. Take out what you need and let them warm before use. I dip them in clonex solution before use

If you're concerned about mold, I'd put papers in a ziplock bag before putting them in the lockbox. I don't think it would needed under most circumstances though; maybe only if it was being stored in a humid basement or something like that.
