Replacing sound proofing in cabniets


I have an old set of speakers I am bring back to life. I have replaced many of the drivers. My next step is replacing the thick cloth material inside the cabinets. Must be used for sound proffing, keeping the sound from bouncing about.
Just curious what people use for this. Carpet pad? Any suggestions sure be appreciated!

Thank you.

There are formula's for the very thing your wanting to do.

The best investment you could make, would be to purchase the 'The Loudspeaker Design Cookbook'.

If you line the walls of the speakers with a dampening product, that will cut down on externally transmitted cabinet vibes. But, if the speakers was designed with that taken into account, then leave it alone.

I'm surprised, but I shouldn't be,that no one here has mentioned the difference in lining the walls and using a fill of some sort in the cabinet, will have two very different out comes.

Filling the cabinet with some sort of fiber fill, depending on the amount used, will change the QTS of the speaker. Changing it dramatically is possible. The more fill used, the larger a cabinet the driver sees, thus changing the sound.

The more fill used, the higher the QTS will be. The higher the QTS, the boomier the speaker will sound, most of the time. There are a million variables, but this is the
general rule.

Whatever the cost is of the book now, it was $30 when I purchased it several years ago, will be your greatest investment. It's writen in a way that most people can understand the concepts. Not rocket science.

Good luck.
