lowering enclosure vent noise

[clays laramie]

Seeing if anyone has had any real success with lowering vent noise.. huffing.. i have a driverside foxbox.. .95 cu/ft.. i have a soundstream rubicon 450 rms sub in it... a little big.. minimum requirements are 1.0 cu/ft..650 rms soundstream mono amp.gain is only half way and it pounds, but some frequencies cause terrible huffing. Tried stuffing socks in it.sounded terrible . and egg crate foam..i think im gonna try attaching egg crate foam to just one side of the port.... any suggestions welcomed...

heard rounding port edges can help, dont really want to start filling down the box un less i know it works...Thanks again

That could help also a sub with less xmax could also work.

I used egg crate foam, but my subs are mechanically very quiet already....some subs are not

^ Yep!

You are going to wrestle with that enclosure for a long time and probably never be happy. Not that there is anything wrong with a Fox Box, it just brings a sound that some may not like.

I know for me, I went from a ported Fox to a sealed enclosure and could not be happier. The bass is smooth and subtle. Probably not a good endorsement as I need to get rid of my Fox Box. LOL

Autokraftgt, i messaged u on another thread about how u put your eggcrate foam in... did u try to line the walls if the port or just shove it in and block the vent? Any sugestions on subs with low xmax that still pound? Only sealed driverside i found was way too small..small mounting depths . troutspinner do you have a netbox or custom?. The wife is already pissed about me dumping more money into the new 50k truck, ordering a new box might just put her over the edge... i was thinking i could slip a new sub in without her noticing...

I am running an MTX Thunderform Enclosure, https://www.mtx.com/drqc20ut-mtx-vehicle-specific-custom-subwoofer-enclosure

I did want a Netaudio box because I wanted to go from 1 sub to 2. Since I knew Netaudio has a lengthy backlog I figured I would find "something" to hold me over until I ordered the Netaudio. That "something" turned out to be the MTX enclosure on Craigslist for $125. Since I am very happy with it I have not given it any more thought.

I know what you mean with the wife and all.

hmm, my messages are empty...anywho, I didn't over complicate it at all. Simply took about a square foot and folded it over a few times and shoved it in. Has held strong for about a year.

My Arc Blacks do not pound, but they're very smooth, transparent, delicate, have great xmax, and move a lot of air. They are not a loud subwoofer, so if you're looking for output, you will not be happy with them. But if you want sheer buttery bliss....they're a very musical sub.

Ok people, i have had some success. I bought a 12*12*1 sheet of acoustic pyramid foam,tried just soving it in and lost alot of db's and it sounded terrible so i cut only 4 rows. So a 4*12*1 piece and put it in the port diagonally... now this has probably changed the tune frequency a little, but it still sounds very close, db's have not been lost and port noise has been greatly reduced... just in case anyone else was fighting this battle...
