Danny Richie's No-Rez Damping Material
« on: 22 Jan 2011, 06:43 pm »
Talk about a cheap and cheerful product. I am very interested in using this for my Silverline Minuets. What exactly do I need to do to install this material? Do I need to disasseble my speakers (someting I've never done before)?

Most speaker cabinets don't have removable front or rear baffles, although there are some that do.  Most of the time installing damping material sheets or crossovers requires removing a woofer and installing through the cutout hole.
 
In your case, with a 3-1/2" woofer and correspondingly small hole, it could prove to be quite challenging, as your hand may not fit through the hole.  You would probably need to remove the tweeter as well.  Of course, some people who have a lot of patience build ship models in a bottle.

If the internal speaker wires are equipped with push-on connectors it will be fairly easy.  If they are soldered on, you would probably need to unsolder the connections to get them out of the way, unless there is excess speaker wire length.  Also be very careful when unscrewing the drivers, as even experienced people have had a screwdriver slip out of the screw and puncture a driver.  It they use hex screws, you have a little built-in safety, but if they are phillips screws, extra care should be taken.

Most certainly those speakers already have some sort of material lining the box.  Probably the hardest thing may be removing the factory deadening material, since the No-Rez should glue directly to the wall.  However, since the No-Rez has its own adhesive, once you have a clean surface, it goes on pretty easily.

Excellent points Steve, as I've gone down the road of installing No Rez and similar material in small loudspeaker enclosures. None of them have been as small as one using a 3.5inch driver. The smallest I've worked with is a Vifa P13 which is a 5.25 inch driver and that was a challenge in and of itself. Partly because it used Phillips screws. The driver frame was also stuck very tight to the baffle as the gasket material used in the build was very sticky.

My favorite quote of the day:

What a wonderful analogy!  :thumb:

In comparison, installing No Rez to my GedLee Abbeys were super easy as it has a removable rear baffle.

Well, that's enough for me not to attempt this.
