Subwoofer dampening

Re: Speaker damping material While there are many options, I brace to reduce vibrations in the cabinet as best I can. I then use regular fiberglass insulation (the pink stuff) with a light layer on all the walls to reduce internal standing waves, and a few layers top and bottom if a tall-thin cabinet.

Find the car subwoofer sound damping you are looking for online at Best Buy. Jun 12, 2010 · Subwoofer finesse is something that I have very little experience with. I can appreciate finesse with speakers which are known for their class leading transparency or smooth clear treble and midrange magic but my experience of bass and subwoofers is its either to much / out of control boomy or tight, deep and good.

You need high density foam to keep the platform from flexing or vibrating, which would result in loss of movement to the speaker itself. Now, you could make something like this yourself. But a 2 foot by 2 foot or 18 inch by 2 foot panel ready-cut at the building supply store, and put perhaps 3 layers of craft foam under it. You can put damping material, such as plastic coatings, on the surround and/or cone (but this usually decreases efficiency as the damping dissipates energy and the material adds weight). Then, there are resonances in the cone itself as the cone flexes. These resonances can also be addressed with the same techniques. Re: Anyone tried NoRez dampening sheets? I've had No-Rez in a few speakers, but never A/B compared with and without. There are cheaper ways to get 'similar' results, but will take up much more time installing. In a larger cabinet, I'd focus on CLD and bracing heavily but in a smaller speaker, I think No-rez is a great idea. Nov 04, 2015 · Dampening/thickening the mounting surface has gone as far as possible, but what I would like to do now is add more mass to the raw speaker basket/magnet housing itself. You see, the speaker uses a very small neodymium magnet and motor assembly but which nonetheless is powerful enough make the raw speaker hop around on the bench. Jan 25, 2012 · Heavy things. Layers of heavy things that are air tight. Heavy things that are air tight and dampened so they don’t vibrate or are made to be floppy in the first place so they will never vibrate, and cover 100% of a wall or ceiling or floor. Sound is simply just a vibration in a medium,...

The selective use of foams and damping materials within a loudspeaker cabinet can significantly alter / enhance it's acoustic performance. These materials fall into two basic types, those that can selectively absorb energy over a limited range and those that can shift / move the energy elsewhere.

Amplifier Damping. With the speaker connected to the amplifer (solid state not valve) that is not turned on, tap the cone with a finger, notice its resonant frequency. When the amplifier is turned on (quiesent without music), notice the difference. The speaker will now behave the same as when a short circuit was placed across the speaker terminals. An amp doesn't have a damping factor. Damping factor is the ratio of the rated impedance of the loudspeaker to the source impedance. In other words, you can only calculate a damping factor when you have a speaker amplifier combination. What you are looking for is an amp with a low output impedance which then results in a good damping factor number. Sound Damping; Sound Damping.
