Soundproofing Cabinets

[Fred19137]

I pulled apart my crate cab yesterday and ther was a whole bunch of soundproofing in it.
I like punchy high pitched sound should I take this stuff out to improve my sound or does it help no matter what. I guess what I'm asking is what is the purpose of soundproofing matterial in the back of my cab?
Thank you for your time

It's not sound proofing, it's damping, and you'll ruin your cab if you remove it. If anything most cabs don't have adequate damping.

The material you are looking at is used to absorb and diffuse the midrange backwave of your drivers. Without it your cab will sound less focused and accurate. I cannot comment on the extent that this matters in your situation. If you are curious there is no crime in trying different things out and seeing for yourself.

I believe that is dampening material. It is supposed to eliminate or lessen standing waves and tighten up bass and mids.

So, this material wont affect my highs?

Fred, what the damping material does is absorb midrange and high frequency energy coming off the back of the cone, so that it doesn't bounce back and re-radiate through the cone. The material also has some smoothing effect at low frequencies, but not as much. Removing it will likely result in reduced clarity with no significant increase in high frequency energy. You're getting as much high frequency energy as you're going to get off the front of the cone already, as the dustcap is probably the primary radiator at high frequencies.
