Thank you.


I notice a bit of rattling when I crank the sub and can't tell if there's something wrong in the room (e.g. the floor is not completely flat) but when I put some of my weight on top of the sub the rattling goes away.

Do you guys think this would help/work with the lfm1-plus?

Or would I need to get the gramma?

You don't need either, as they don't do anything that a piece of carpet doesn't do. One potential issue with a downfiring sub is that the movement of the cone will cause the sub to move up and down (see: Newton's Third Law of Motion) at high output levels. A piece of carpet, carpet pad, or this, cut to size, will absorb vibration between the feet and the floor:

Or you can add enough mass to the sub to overwhelm the forces created by the cone movement, but sitting on the sub to watch a movie may not be the most comfortable alternative. rolleyes.gif

Thank you Bill. I'll see if I can find a black one that can blend in with the plus.

When I purchase this, should I use the spikes only or do I use the supplied dimpled disks on top of the padding you linked me to?

You need to use the spikes to lift the cab off the floor. They include those discs for use on hard floors, but from user reports like yours it doesn't seem they're totally effective. I don't see why you couldn't use them atop padding or carpet, but I doubt they're necessary. And it needs to be said again that hard floors are the worst enemy of good sound.

I can't seem to find a black one that won't look ridiculous under the plus? I searched padding in walmart and all I see is either the blue camping pad or beige cushion

Carpet matting or carpet pad. If you have a "Prime" membership, shipping in included. And with strong hands, it can be cut with scissors. If the hands aren't so strong, than a straight edge or compass and box cutter.

Maybe a carpet shop or rug shop. Don't know what Walmart has to offer.

Ok so which is better in this situation a carpet/rug or some sort of padding like the camping pad from walmart ?

Both will work equally well. I'd hit the nearest carpet store and see what they've got lying about for remnants. The only thing that probably wouldn't do the job is a very thin carpet/rug.

The carpet and throw rugs are fluffy and porous by comparison to underlayment pad and easily compacts where as the padding has much tighter fiber weave and is designed/constructed to be supportive of the carpet above it; better long term wear characteristics and is constructed to be installed on interior household flooring.

Camping pad is soft and porous for elbows and knees and won't hold up like the dense fibers in the recommended carpet pad which is constructed to support years of daily foot traffic.

I use a square of black puzzle mat - similar to these - under each of my down-firing 18" subs.

You can find them at Sams club if you have one near you, if not Costco may have them. Do you have one port plugged on the Plus? If so try taking it out and putting it in the other port to see if that stops the rattling.

That's heavy duty stuff. I'd say two inch square pieces of that under each spike would do the job.

At ACE hardware I found an $8 pack of four 3" diameter disks made from 1/2" thick material like the black puzzle mat above glued to 1/8" of felt. I put one under each disk of an Outlaw LFM plus.

It might be this, but I'd need to see a side profile to be sure it is not just felt, but includes the 1/2" rubber as well.

But isn't this a bit on the large side for a 15" wide 21" deep sub?
I only have about 2 inches of clearance on each side of the plus.

The mats can be trimmed.

Would it be difficult to cut with a straight edge razor?
Also if you don't mind, may I see a pic of how your subs look like with these mats?

Patiently, and with a sharp x-acto knife, it can be done. I don't know about a straight-edge razor.

Sure thing. smile.gif (NOTE: While I haven't trimmed the mats under my subs - because I like how they look - I have trimmed other squares that I've used elsewhere. But I've discarded those squares, so I can't post pics of them.)

Just in case this point was missed, as an add, the puzzle mats have edge pieces which provide a finished edge if one doesn't like the interlocking edge look. For a gym floor, we have the 3/4" (~19 mm) version in the garage and they've worn very well over the three years we've had them.

This is the online source we purchased them from.

Use a utility knife with a fresh blade, use a framing square to guide the blade for a straight, smooth cut.

I ended up buying a cloud 9 memory foam mat at walmart for $6 and some rubber washers to make the spikes a bit taller and give more clearance between the woofer and the mat and it seems like that did the trick and almost removed it completely.
I picked up a second to put under it to completely remove the rattling we'll see how that works out.

I guess that might work, though it seems a bit thin.

It was 17×24/black an almost perfect fit for the plus and it was only $6 so I decidedpto try it and suprisingly even though it is very thin, it removed the noise by about 90%. A second one should surely eliminate it completely.

I also removed the dimpled disks so I'm only using the spikes on the rug.

That will allow them to eventually penetrate through it and you could end up practically back where you started. I'd use the discs. You wouldn't need the discs on a full fledged carpet with pad.

Ill try it with the disks but it seems to me those are the cause of the rattling

I can see that if a spike wasn't tight against it, as would be the case with a floor that isn't flat. The rug should take care of that, especially if you use two.

From the reviews I've read and the recommendations the lfm1 plus should be more than enough for this room. Thank you guys for all the help! Ill post pictures when I recieve it smile.gif

Outlaw had a sale. They usually have their subs on sales like this one a couple of times a year. Gotta act fast, because once they sell out the deal is over. OP got a great deal.
