Bronze Member Username: Lil_jonPost Number: 93 Registered: Jul-05 | I was at a JL dealers today or yesterday for some instalation, and I brought up my car and asked them how well will a 5cube ported BOX do in a Eldorado Playing 2 ''15s? and this is a fe w things what they said 5cube and 15s are usually for suv because theres more space and longer wave length In a Car 94 Eldorado, The longer stroke of the 15 wouldnt sound so good because the sub could be too close to the trunk, Therefor the 15 would not reach its potential because of the shortning of the wave length. But he said the sealed would hit harder and the ported would be louder what would sound better for my car? 4cube sealed or 5 cube ported? With wave length in consideration. I need it to be very very very loud and go very low or I know me, I will damage the woofer trying to get more volume out of it, |

In general, you really need at least 6" of free air space between the sub and the back wall of the trunk. Anything less and the low frequency, 15" or 18" might produce can or may be cancelled out. Just as port length can tune freqencies, so can a trunk space. If you have RTA, try a little test. Put a sub 12" sub inside and play 20Hz - 150Hz tones. You will notice that, at certain frequency, it'll generate more SPL. Now repeat the same test with 18" sub. The frequency that was loud with 12", will not be the same with 18". The point I'm trying to make is, the volume of the trunk can have some effect on tuned frequency. Go vented, since you want SPL. |

I have mine at 2.2 sealed and its more then enough for me and it hurts my ears at loud levels and i listen to mostly rap but it sounds good on every type of music in this box. Im using a CrossFire VR1000D and the gain is like less then half way and it just pounds. Im using a Pioneer Premier 860. Very Loud and Clear once you install it right and EQ it. p.s. much louder then my 2 JL 12w6v2's sealed. |
