New member Username: Jay_boyRochester, NY Usa Post Number: 1 Registered: Feb-10 | I just ordered 2 8w7s, a sealed box (jl specs) powered by a jl hd 750. I'm looking for HARD punch without missing beats. Is this going to work? What can I expect? |

New member Username: Jay_boyRochester, NY Usa Post Number: 3 Registered: Feb-10 | Yes, after the fact. I am very anxious. It feels like xmas so bear with me. I'm just curious if someone already knows what this will sound like. 8s and sealed should produce HARD hits. right? 8w7 with 750 rms should be loud enough but very hard and accurate? |

New member Username: Jay_boyRochester, NY Usa Post Number: 4 Registered: Feb-10 | Also, how come multiple small speakers still create monster bass. example bose 901 were 9 little speakers with big bass. Will having two 8w7 also produce better bass than just one? and in what way? |

Silver Member Username: Simple_smithLapeer, Michigan United States Post Number: 281 Registered: Dec-08 | Not so much hard as accurate. sealed is all about accuracy and SQ. the two 8s will have more cone area than a single 10 so thus, they'll be louder. |

New member Username: Jay_boyRochester, NY Usa Post Number: 5 Registered: Feb-10 | how is excursion of one speaker compared to that of multiple speakers. ex. if my Xmax of 8w7 is .75 and I have two, is it doubled to be more that that of a 13w7 which is 1.25? |
|
Silver Member Username: Simple_smithLapeer, Michigan United States Post Number: 283 Registered: Dec-08 | to a point because the total SPL is directly affected by both excursion and cone area. i'm not an expert, but i think that sounds right lol http://www.bcae1.com/speaker.htm |

Silver Member Username: SkdooleyRoanoke, VA Usa Post Number: 287 Registered: Oct-09 | The w7s are designed to have more excursion than your average woofer of equal size. How hard they hit is going to depend on the size of your enclosure, that's why custom enclosures are better than pre-made, because then you can design it to meet your expectations. I still say you'll be happy but if you wanted them to be any louder, a custom ported enclosure would be the way to go. As people have stated, sealed is more for SQ. w7s are geared toward SQ so they'll do well in a sealed enclosure. If you find yourself wanting a little more out of them though, ported will do it for you. What kind of vehicle are they going in? |

New member Username: Jay_boyRochester, NY Usa Post Number: 6 Registered: Feb-10 | Great feedback. Thank all of you. 2009 elantra. I can change the enclosure later if necessary. it was $140. Not a biggie. I just don't like the inaccurate rumble. I like tight and snappy. We will see in a couple of weeks after install and break in period. Any other feedback or info will be appreciated. It's a huge investment that I have been waiting many years to do. Hope I haven't blown it. I don't think so. |

Silver Member Username: SkdooleyRoanoke, VA Usa Post Number: 290 Registered: Oct-09 | You could have also went with a 10w7 in a custom ported enclosure. Would of maybe been a little cheaper and sounded just as good. If you put those 2 8w7s in a ported enclosure though they will slam just the same. Should sound good. |

One of my best friends has the exact same set-up in his pick-up and it sounds very nice. Highly accurate and extremely punchy. Good luck man! keep us posted. |

New member Username: Jay_boyRochester, NY Usa Post Number: 7 Registered: Feb-10 | Nice to hear from someone who has actually heard the same system. The sealed enclosure was purchased from a guy through ebay that makes the box to JL specs for $110 plus shipping. He is on Long Island. I'm just waiting for the amp to come in. I appreciate the feedback and I will let you know how it sounds. |
