Sub box questions.
Hello again,
I am going to be buying a sub(s) soon and I had some questions: Should I go with a sub that comes with an enclosure or just go component and build the sub box? Do you guys know any tutorials on how to make a sub box that will give me the low frequencies? How many subs do you guys suggest for a guy who listens to everything but rap? 1 or 2? Would it be better to put the subs in the trunk of my sedan, or somehow get them in with the passengers? |

Most pre-built subs resonate in the 50-80 Hz area. A larger box or using the trunk as the enclosure can get you down to 20Hz or lower. You'll need a compatible sub, of course. |

Hello again, I am going to be buying a sub(s) soon and I had some questions: Should I go with a sub that comes with an enclosure or just go component and build the sub box? This really depends on your skill level. If you are good with working with wood, then some money can be saved by building your own enclosure. But I think you will tend to find that pre-made enclosures tend to be pretty reasonably priced. Do you guys know any tutorials on how to make a sub box that will give me the low frequencies? Check out this group's FAQ at http://www.mobileaudio.com/rac-faq/ . It will give you some good advice about what kind of box you may want. How many subs do you guys suggest for a guy who listens to everything but rap? 1 or 2? Rap is not the only type of music with low bass. If you like techno, there is TONS of low bass in that kind of music as well. I've noticed that in the last 10 years pop has become bassier and bassier. And even modern country has lots of low bass as well. I find the question isn't really about the kind of music you like as almost EVERY type has bass, but how much bass and how loud do you play your music. That being said, I have two 12" subs and that seems to be perfect for me. Now I'm 38 and I listen to all types of music. But I DO listen to some rap and techno and on occasion I like to REALLY FEEL my bass. I also like to crank it WAY up now and again. If this does not sound like you, then maybe a single 12" sub will do the job. A single good quality 12" sub will provide enough bottom end for almost any kind of music at moderate to loud volumes. Would it be better to put the subs in the trunk of my sedan, or somehow get them in with the passengers? The trunk is usually fine, in fact, the trunk is the BEST place. Bass is omni-directional and can travel through upholstery with ease. When you mount it in the trunk facing the rear (or better still, the corner), the bass is able to "load" (or concentrate) and this tends to produce the strongest bass because you have the least amount of cancellation. The same is true of subwoofers in the home, they work best when placed near a wall or corner, again the reasons are the same. MOSFET |

I had a couple questions about the infinite baffle sub box. Will it give nice low frequencies? Alright for the trunk? Recommended? Also, I was thinking of a ported box, but I had heard that there are calculations and stuff in order to get the frequencys right. Do you know of a sight that is more specific on building a ported sub box? Again, thank you very much for all the info. |

Sub box questions.

By infinite baffle, I'm guessing you mean a Sealed Box. One where the sub is mounted in a box with no holes, right? (Just thought I'd clarify that first) I've always had three concerns when putting a system together. First, Money. I don't have a lot, and didn't want to spend butt-loads of money to have a decent stereo. Two, I don't want to be that asshat who you always hear coming from (sometimes literally) a mile away. And three, looks. I didn't want it to just be something thrown together. What I ended up putting in my car was one 10 inch sub, powered by only 150 watts rms, in a ported box tuned to 26Hz. The Head unit takes care of the four 6.5 inch speakers inside the car. That works for me. I listen to a lot of techno, hip-hop, and rap, but I also like some good rock, and some soft stuff (think Counting Crows). Sometimes I'll rock out to all sorts of wierd crap on the same ride... Sometimes I get out of the car with my ears ringing, sometimes it's just background noise while there are others in the car. You can see my setup he http://www.cardomain.com/ride/2367650 So all that being said, I think that you should build a box. I recommend building a sealed one, to start with, using your subwoofer manufacturer's recommendations (really, to begin with, stick strictly to those). If you like how that sounds, GREAT! Don't do anything else. My guess is that eventually when you're ready, you'll want to play around with building a new and possibly different box... You'll want to play around with ports, and different materials, and more power.... Your car stereo mania starts there. That's what happened to more than a few of us out in the world. Welcome aboard! ~Mister.Lull Just to clarify, by infinite baffle, I meant the type of boxes that have the sub turned around with the front pointing into the box as opposed to pointing out. I heard that you get lower frequencies with that and was just curious as to your guy's thoughts about them. What I am looking for is a cheap way of getting the low frequencies(33 and below). But I do really appreciate your input and think I will start off with a sealed box and see how I like it. Thank you very much. P.S. Do you happen to know of a good site for calculating ports and stuff for a ported box? |

Personally, I prefer the WinISD calculator. There are two versions
(alpha and beta), and both are free. To begin with get the Beta version - it's slightly simpler, and more user friednly... :-) ~Mister.Lull Vivek wrote: | Just to clarify, by infinite baffle, I meant the type of boxes that have | the sub turned around with the front pointing into the box as opposed to | pointing out.

Should I stay as close as possible to that number, or make it bigger or what? Also, can I make a box with twice that internal area and use two subs in one big enclosure or should I keep the subs separate? |

I would suggest to build the box with slightly higher dimensions say .70 cubic feet. You can always put bracing to decrease the volume. | Also, can I make a box with twice that internal | area and use two subs in one big enclosure or should I keep the subs | separate? If one sub sometime breaks then the other will also sound bad (boomy). Build a single box for the two and put just one divider wall. This will divide the box and will also strengthen it. |

Thanks for the advice. If you dont mind answering another question: What is the advantage of putting the front of the subwoofer pointed into the sealed box with the rear sticking out? Different sound or just for looks? Like so: http://www.theloudest.co.uk/admin/si...95_5_large.gif |

No difference in sound quality. The only difference is in the volume
calculations for the box. I believe you know how the volume is different. Advantages: - If you underestimated the box volume, you can compensate it by "sticking out" - It looks cool Disadvantages: - Hard to make it stealth. Easily gets the attention of thief.
