Your the "dumb" one I described above. Tight bass has NOTHING to do with sub size. So you are saying that you can get the same tight bass out of a 15 that you can out of a 10 I think not.. I know that the box has a lot to do with it..... But if you don't know how to build a box you wont get tight bass.. Dumb ass. Lets see you get tight bass out of anything else. and in tell you can prove it keep your friggin mouth shut. If you want to go out of your way to be ignorant I'll play. I can be VARY ignorant. want to see Hmm, yeah probably not a good idea to badmouth a moderator if you want to continue posting here. Especially when you're wrong. If you don't know how to build a box you won't get tight bass out of a 10" either. Ever been to a club with a concert playing? If they have dedicated subwoofers and not just 2-way monitors, a lot of the time the tight bass you feel is from 18" drivers. And I'll put in that my ported 15" SI Mag v.2 is one of the most accurate subs I've heard. I did say that the box makes the tight bass, and if you are a mod it not a good reflection on the forum if you are ignorant. And my JBL WGTI 10's are the tighest most controlled subs on the market. the Wgti is the tightest most musical sub I have ever heard in car period.... the differential drive coil / motor assembly is an unfair comparison to a conventional motor design BUT....I SMOKED about 5 or 6 of them in 6 months completely filling the car with smoke EVERY TIME........and JBL does NOT sell recone kits for them......... ............. FAIL!!.............LMAO
