X2 on the price \ DB output.
I have settled a family arguement about ported vs. sealed using the knowledge you guys gave me through the years //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif. My pair of Orion P series 10" subwoofers hit 130+ (wal-mart db meter) at the dash of my van with the subs 13ft away making my windshield wipers bounce. I shut out 4 visonik 10's to end a 2 1/2 year audio arguement about ported sux compared to sealed when my IB setup with those 10's astonished my shit talking cousin's and shut them up. Now the new arguement is to be settled, they argue to their blue in the face saying that 10's hit the low's better than 15's or 18's ((mind you they have not researched anything you guys provide that I have learned from you all)) , and so now I am going to use these cheap 18's to hit harder than my previous setup, and also to show 18's not only hit the low's better , but are louder , and can sound just as clear but more than anything they dont beleive a pair of 18's will have the punchy bass a 10 does. So any input on my quest here to prove them wrong would be nice.
