2 subs ported vs. 3 sealed
|
Silver Member Username: Monkey_manPost Number: 180 Registered: May-05 | Okay. I was just wondering, would 3 sealed subs be better in (sq? sql? spl?)or would two subs in a huge ported box be better in tho's catagories? This is asuming that the all the subs are the same. Your help is greatly apreciated. -Thanks |

In the ported example, you get 3 db per cone (6 dbs) + 3 dbs for the ported boxes. 6db + 6db = 12. The sealed you would get the 3 db per cone, making for a total of 9. You would obviously have better SQ with the sealed, tho. |

Silver Member Username: Monkey_manPost Number: 182 Registered: May-05 | Okay thanks. I am trying to figure ou which i like more. I still havn't figured out if i like SQ or SPL better. With that in mind, Could you still hear the bass outside of the car. I mean i really want people to know when i am comming down the block, but i also want the bass to be clear and crisp. |

If your tuning was low enough SQ would still be good depending on the sub you choose but with higher port tuning the sealed enclosure will have better sq with less spl. another thing you have to take into account is the amount of power you are going to give each driver because 2 ported with 500 watts each will be much better then 3 sealed with 333 watts each. |

Silver Member Username: Mikechec9Chicago/atlanta Post Number: 253 Registered: May-05 | the primary determinate, imo, is which subs/amps you are choosing. if you get the good stuff then the added 3db may be a moot point. when i ran 3 w3's sealed, i often had to open the windows because my ears would hurt (sooo literally). the biggest advantage (imo) with ports is the volume of the depth/bottom end. i havn't heard any ported systems that were sq based per se, but i know they exist. it takes some technical tuning and time to get a good sq ported box. but with 3subs (good stuff), i would personally go sealed. |

Gold Member Username: James1115Wilton, Ct Post Number: 3498 Registered: Dec-04 | yup. I ran 3-10w6's and with 600 watts it sounded so clear and in the upper frequency range got so loud it would hurt lol! if you do 3 subs get dual 6ohm that way you can wire them to a 4ohm load or a 1ohm load. |

Silver Member Username: Monkey_manPost Number: 183 Registered: May-05 | Well, i have 2 alpine type e's. In a ported box tuned to 36 hz. The cubic feet total is about 3.2. I am planning on buying a orion hcca 250. So, wattage isn't really a problem. If i don't get it then i want to find an amp that is aprox. 800 watts at 1 ohm and 400 at 2 ohm etc. Does this change anything. What are your opinions? |

Silver Member Username: Mikechec9Chicago/atlanta Post Number: 262 Registered: May-05 | not sure if i understand your question. but that is exactly how i ran my trio of w3's. w/a audiobahn 8001dt. 800w/3 @1ohm |

Silver Member Username: Iufan4lifeulLouisville, Kentucky Post Number: 152 Registered: May-05 | Its basically like this Sealed- Better sound quality, tighter response/quicker response Ported- Louder, Louder, and terrible quality (well, usually) IMO 3 sealed vs. 2 Ported... I would personally choose 3 sealed any day. I think that the 3 sealed might be a little louder or the same as far as SPL but it would blow the other 2 away in SQ. Just my opinion. |

Silver Member Username: Monkey_manPost Number: 184 Registered: May-05 | Okay then thats what im bout to do den. Cuz these subs are only like 60 on ebay. |

Gold Member Username: Jonathan_fGA USA Post Number: 4166 Registered: May-04 | "Sealed- Better sound quality, tighter response/quicker response Ported- Louder, Louder, and terrible quality (well, usually)" False. Ported gets a bad reputation because it's more difficult to implement correctly than sealed, sealed is pretty much goof proof. Your typical prefab ported boxes perform more like a leaky sealed box than a true ported box. A well designed and built ported box can hold it's own with any sealed box in sound quality and outdo it in SPL. It just takes the equipment and knowledge to take advantage of it. Look at 5 figure home audio systems and see how many use ported enclosures, there are a gracious plenty. This article is VERY informative and clears up a lot of false misconceptions about ported boxes. http://www.hometheaterhifi.com/volume_5_2/cmilleressayporting.html |

Silver Member Username: Mikechec9Chicago/atlanta Post Number: 264 Registered: May-05 | well, keep in mind that if they are not sq subs, you can run sealed all day, but you won't necessarily get that sq you're looking for. just mentioning it, b/c if your getting 3subs (or even one)for 60 bones, you might possibly be better off ported. what kind of subs are they? |

Gold Member Username: InsearchofbassPost Number: 2944 Registered: Jun-04 | jon is right and i know from personal experience hes right form a kicker 12 we had sealed and switched to ported. Sometimes a speaker will not lend itself however to a chioce of both sometimes you have to choose sealed or ported depending on the theil small parameters. I too get defensive about the sealed having better sq tho.. its so false |

Silver Member Username: Mikechec9Chicago/atlanta Post Number: 269 Registered: May-05 | everything in perspective. as i stated earlier, it takes considerable time and technical tuning for a good sq ported enclosure. i mean who wouldn't like the best of both worlds? but he still hasn't disclosed his subs or amp. only that they are 60 bones on ebay. so basically, such a box is going to be considerably more than the drivers so i don't think that's going to happen. the scary part is, you have to really trust that someone IS using the proper equipment and such (that jonathan mentioned). cuz once the box is built, its built. i have been stuck like that before. thanks for that article jonathan. it was very helpful. if i didn't have so much power, i might reconsider the enclosure we discussed for my brahmas. |

Gold Member Username: Jonathan_fGA USA Post Number: 4168 Registered: May-04 | "lol again jonathan gets all defensive over his ported boxes"  . I'm actually running sealed in my truck right now, but I've used ported many times in the past and it has it's benefits for SQL. Mainly an issue of personal preference and the application than which one is better than the other, both have their pros and cons, both for SQ and SPL. |

Silver Member Username: Monkey_manPost Number: 185 Registered: May-05 | Well my subs are alpine type e's. The ones that best buy sells. I am not sure if they have good spl but i think alpine is more a sq brand. Am i right? What should i still go with? Ported 2 or sealed 3? |

Bronze Member Username: Dz43893Chicago, Illinois United states Post Number: 61 Registered: Jun-05 | best buy sells type r's well atleast the 1 by me they sell for like 200 right? |
|
Silver Member Username: Monkey_manPost Number: 186 Registered: May-05 | Yeah the one in seattle does. But, i really need to know if i should go 2 ported or 3 sealed. I'm thinking more sealed but what u guys think? |
