Help with subwoofer
|
New member Username: Jd93kidBrandon, MS U.S. Post Number: 1 Registered: Jul-09 | Alright, hi everyone, I need help deciding on a subwoofer. I only have about 250 dollars to spare. I have currently been looking at the alpine type r 15" dual 4 ohm sub. I have an alpine mrp-m850 amp with 800 rms at 2 ohms and 1500 watt peak at 2 ohms. Please list your opinions on what i should do. I also need help getting a box. I am going to buy one i just need to know the size of the one that will be best for the sub I get. |

New member Username: Jd93kidBrandon, MS U.S. Post Number: 4 Registered: Jul-09 | I think i am going to go with the type r 15" I need help on the box specs. It is going to be ported just because i like ported better. Need opinions!! |

New member Username: Jd93kidBrandon, MS U.S. Post Number: 7 Registered: Jul-09 | I do. I dont really have the equipment. I also have a friend who offered to.. I just thought i could get some help, but to tell you the truth your really not helping that much. I have the specs alpine gave me, but i have heard that it is better to build it slightly larger than they say to. |

New member Username: Jd93kidBrandon, MS U.S. Post Number: 8 Registered: Jul-09 | alright. and i dont think it really matters who told me.. but if you really want to know. It was on another forum i read. I can try and find it for you if you really want but, I dont think it will help you in anyway. But thank you for that. |

Silver Member Username: Kingandsons07TEAM NEBRASKA Lincoln,NE Post Number: 671 Registered: Aug-08 | well it hard on the sub if the box is to big, if the box gets to gig the sub will bottom out, and are you going ported? |
|
New member Username: Jd93kidBrandon, MS U.S. Post Number: 9 Registered: Jul-09 | Yeah i wouldnt want that.. yes i am going ported.. why do you ask? |

Gold Member Username: The_image_dynamicSan Diego, California Post Number: 5273 Registered: Dec-06 | What he read was to make the box on the larger side of the specs that are given, which I agree with. Alot of manufacturers nowadays spec as small of a box as they can because they know this is an important factor to some people. In fact alot of subs' claim to fame is: "Works in a very small sealed or ported box." The magic numbers for the 15 (for me in the past) are 2.4 cubes @ 29hz. Grab a dual-4 and wire it like the pic below and you will be all set. It will be an almost perfect match with that amp.  |

Post Number: 3626 Registered: May-07 | going slightly larger or at least on the bigger side of the company's recommended specs (port area/enclosure volume) shouldn't hurt anything.. It really depends on what performance you are wanting out of the sub.. Usually (there are exceptions) slightly larger will tend to be more musical sacrificing a lil spl. I have never tinkered with the 15" Type- R's but have a lot of experience with the 12's. Honestly with that amp and sub combo, I see no reason not to go with Alpines recommendations. |

New member Username: Jd93kidBrandon, MS U.S. Post Number: 10 Registered: Jul-09 | Alright thank you.. I will prolly go on the slightly larger side of the specs. Thanks for all of your help. That is exactly the information i was looking for. I appreciate it. If there is any other information I might need please tell me. |

Silver Member Username: Kingandsons07TEAM NEBRASKA Lincoln,NE Post Number: 672 Registered: Aug-08 | ok good i was hoping you understuted not to big or that could happen. someone came on this forum asking about bigger box's and the box he had was 5x bigger then what he was to be using, and i was going to ask what were you going to tune it too? |

Bronze Member Username: Jd93kidBrandon, MS U.S. Post Number: 11 Registered: Jul-09 | ha wow. Yeah the last one i had built by well we'll just say he wasnt a professional and i measured it. It was like almost twice what it was supposed to be.. It ended up making the voice coil heat up and ruined the sub. It sucked |
