How to insulate a speaker box?

Author: admin  |  Category: Home-Fluffing

I have a home made speaker box that sounds excellent. and It is ported. I want to make sure that what I did to insulate it was right.
I placed some acoustic insulation on the top panel, bottom panel, and on the back panel paralell with the port. I fluffed it in. What I am trying to get across is that I did not insulate the entire box.
It sounds great but i was wondering if I could get it to sound better by insulating different or will it not make too much of a difference. thanks.
I have ported with a tube.

If you want the Bass to have a little more punch, and sound "bassier" then go to a craft store and buy pillow stuffing, or quilt stuffing. fit as much as you can in the box. just keep it off the speaker contacts

    Try adding more insulation and listen if it is better or worse. Do you have a bass reflex loaded port with a tube insert resonator, or is it just the port without the resonator? My speakers are bass reflex with a loaded port.They have about 2 inches of corrugated foam attached to five inside panels.These are manufactured speakers (Rogers ) and they sound excellent. Here are the Specs.This info. may be of some use to you.

    3 way bass reflex.25ins. high. 12 ins. wide 12 ins deep.
    nominal impedance 8 ohms.
    sensitivity 86.5 db sl
    Frequency response 45 to 20k hz +or – 2db
    power rating continuous 300 watts
