Hello,

I am currently running 2 Hertz Mille 10'' subwoofers in a ported enclosure. My taste in music has shifted in the recent months from predominately Hip Hop to genres encompassing musicians like Pink Floyd, Tragically Hip, Elton John, and RHCP.

My question is, should I seal off my current enclosure or remake the entire box to achieve more SQ bass? The only constraint on this decision is the cost as my current enclose was custom and quite expensive. I would like to know if there will be an audible difference in base quality if I seal the port as opposed to building a new sealed box.

Your insight would be appreciated.

wha twas the box you have built for ? if it was built for daily driving then there is no point in changing it cause it was probably tuned around 38 hrz which id good for most music

 

The box was built for a daily driver, but I would like to compete.

 

Depending on the size...you may need a new box. Most sealed boxes are smaller than ported. Especially if your competing in SQ.

 

Could the volume of the box be reduced by adding layers of fiberglass etc?

 

Why do you think you need a new box?

Does it sound inferior? or inaccurate?

competitors do not need a sealed box as a right of entry, nor is it even really desired, merely having a sub and box that produces clean/ accurate and powerful bass.

 

Change your xover points and drop the gain on the subs. No you don't need to change. That box sounded great when I was tuning it. Buy the IASCA CD and play with tracks 6-7 get it sounding right. Try 40hz at 12db or 18db. bump up your 20 hz to +3 or higher and see if you get the air pressure change on IASCA's track 6 at 1:09. Work with what you have and find out from hertz if you use sealed and at what volume.

 

Just remember though that the iasca cd should only be used as a reference, when tuning it to fit your tastes use high quality recording of music you plan on listening to on a daily basis.

 

I have an OLD IASCA set up disk you can have if you want.

 

In many cases, a lower qtc will improve SQ...so a bigger sealed box might not be a bad idea.
