I need to know what genre of music you listen first off and of what age... new school ( 1999 to present ) old-school ( 1999 and down ) this is important to know for the so that I can understand the bass style you listen to...


plus if you what give me the box outside dimension, I will design a new enclosure for you.

listen to mostly rap and some r&b but feel free to design however you like max diemensions are 15 tall 34 wide 17 deep

Here is a nice design that will give you what you want.... solid performer and the bottom end will be solid.

Just remember to follow the design exactly!!!!

Hi Matt, Ummm... is there any difference between the old school bass and the new school bass?

-Thanx-

[noobs]

Also Matt, I'm Currently I'm using your box design for IDMAX 12V3 2,5cu ft tuned @28Hz with polyfill. Will it accomodate the old school bass? Or I need new box?

Sorry if i asked in the wrong thread. But I just curious about the old school bass and new school bass.
Old school bass is refering to sumtin' like Two Live Crew bass?

=Thanx=

new school has a deeper sounds to it wi\th more rumble and less bang to it.

Old school is more boom and impact and less deep rumble.

Hi Eric.
Oh nooo... I like old school bass then. No wonder I keep on complaining about the sound. U remember my thread do u Eric? Currently I'm using the 2,5cu ft tuned @28Hz for single 12V3 IDMAX. Can the box handle old school bass? Or I should ask Matt to design a new box for me plz? Size doesn't matter. I'm gonna use 25mm MDF board.

Should I continue asking here or just plz move my post to my thread?

Thanx

designing a new one for you right now... have if up later

Whoaa... thanx a loooottt Matt.
I want the loudest old school SPL.

[noobs]

BTW, Matt. Does car cabin gain related to the tuned box freq? My car cabin gain is around 50Hz. And how do you design a suitable box? Can u give short tutorial perhaps? I just wanted to learn how to design a good box for sub. Maybe I can experiment with it too.

No short answer... but I do consider transfer function of the cabin into the box... this will always help in the bottom end... I will show you what it looks like when I post the box up.

here is your box and this should be nice...

if you want to have some fun I have never tried this myself but instead of stuffing the box you could instead stuff the port, what the effect is like in theory is bottom end of a ported box but with the group delay of a sealed box. same box and port just stuff the port with .5 pounds of fiberglass and some how cap them with grill cloth...

Ummm..... excuse me Matt. A lil' mistake here. I'm using single IDMAX 12V3 not IDQ. Sorry... but i guess there's some misunderstanding here.

You are are kidding I missed that totally... making it now.

Hi Matt, is the box for single IDMAX with old school SPL bass already finished?
Here is the real link for the thread Which box is better for single idmax

-Thanx-

I stumbled across this thread (since I am new) and would like to bring it back from the dead to see if anyone can elaborate on this technique of using stuffing in a ported enclosure. I have tried this and have been impressed somewhat with the results but I was just wondering if there was more to be had by means of tuning the amount of stuffing in the port and conceptually how this differed from a aperiodic enclosure.

In simple terms a stuffed port is still a Helmholtz resonator so it is still a ported box but the stuffing will damp its resonance just like it damps the resonance of a speaker in an resistive membrane (aperiodic) enclosure.

Think of damping like a shock absorber it controls the spring and reduces ringing in the circuit, this translated into better transient performance and less distortion.

That is very intriguing to me. Should these ports be stuffed tightly to flow little air or only partially stuffed? My setup used two 8" long ports that I stuffed along the full length and capped with screen-material but I figured that this way the woofer would act mostly as if it was in a sealed box but to me it sounded much more impressive than a sealed enclosure. I had wondered why...

[Eric Stevens]

Lightly stuffed but it is affected by many variables. Testing is the best way to determine the amount.
