Deep rumble from a sub in sealed box?

Can I still get the deep, loud, earthquake like rumble from a sub in a sealed box? I know bandpass is probably the best way to get that but I don't have the room. And vented would work but you need more room for those also, right?

Yes you can certainly get deep rumble from a good quality sub in a sealed enclosure.

Vented is better for an over all rumble because bandpass will only rumble at basicly one note. You can definatly get the sound you want from a sealed box as long as you have a good driver, a well made box and a good amount of power to go with it.

One way to increase the "rumble"  is by stuffing your box with a material called polyfill.  Its basically pillow stuffing that kind of looks like white insulation.  It can be found at craft stores, or in the craft section of walmart.

not true alpine guy. Thats only to fool the woofer into thinking its in a larger enclosure, if his box is already larger than spec, that wont help him at all.

To answer Chappy's question about sealed enclosures, yes you can. Check my car out. 2 sealed enclosures, and I still have a good amount of usable trunk space. Does the bass get low? Let's just say my "all about sound quality" friend respects my system (and he isn't much of an SPL guy). But like Ravendarat said, make sure you have enough power and a well built box. If it doesn't sound deep enough, try adding polyfill because maybe the box is a little too small, because for me it certainly did help.

Don't like rockford subs? Then don't look at my car =)

The key to this is matching the space available to determine the volume of the box - next match the sub to the box and the amp to the sub. A sealed box can play some amazingly deep bass if the system is matched together properly. My favorite in this application is the Eclispe aluminum sub in a 1.25 cu.ft. sealed box with the right amp to power the sub or subs. An Audio Control Epicenter is also a nice addition to a system like this as well.

Top Secret, I can tell you but then my wife will kill me.

Thanks everyone. I am going to be making a custom fiberglass box in the spare tire well. It has a diameter of 32" and it is at least 9" deep. I know I have around 4cu ft of space. I haven't done the math correctly yet. Some 10" subs meant for a smaller sealed box should work well. I just need to figure out a good way to protect them from anything i may put in the cargo space of my jeep such as groceries.

Uh, hold on.  No, I suggest you really don't want to put a 10" sub designed for a smaller space (for a 10" typically around 1 cuft or less) into a 4 cuft sealed enclosure, unless you really know what you're doing and you run them on about 1/4 rated RMS power and use a high-pass filter at, oh, about 25Hz.  Plus, I suspect it will sound like crap in that large an enclosure.  If it's going to be 4cuft, then port it and get a sub designed for that size enclosure.

I was going to have four 10" subs in the box. If each sub needs 1 cu ft then  I will  seperate the box into 4 chambers that are 1cu ft each. That way I know that all 4 subs have the proper amount of space. I'm sorry if I didn't say four earlier. Made me sound pretty dumb.

Ah, that makes a lot more sense.  4-10's in 4 cuft would be a much better!  :)
