In Reply to: RE: is it normal for a car sub to rattle in free air? posted by Mr Peabody on December 29, 2016 at 20:15:18:
i'll be using it with a planet audio BB1200.4 in biamp mode with the rear channels bridged for the sub, and the fronts driving a pair of nice sounding 96dB proel flash 8Ps as mains. this is actually going to be a bicycle trailer system.regarding ports, yes, i'm fully aware that they add distortion, i mean out of phase resonant harmonics that don't exist in a recording to give an illusion of bass, but i despise that bloated marshmallow sound. i like the tight thump of sealed speakers and and more than happy to sacrifice SPL for SQ.
it was a tiny pair of $100 4 1/2" infinity 2 ways a buddy demoed that gave me my very first taste of what my eras consider hifi despite numerous previous visits to 4 different shops. it was the first time i heard low distortion lightning quick tight bass and THAT was what wowed me (THUMP!), not big sloppy, put the boo in boom, klipshes etc. (that, and imaging)
this is just version 1.0 of the system until i find some part time work to be able to afford upgrades, and i'm thinking about a downward firing 4x12 fiberglass system with L/R mains on each side.
the JBL has outstanding specs for the 1.9 ft3 box i bought it for. JBL recommends 1.5-2.0 ft3 even though the Q is on the high side at 1.15, if memory serves me right. i already have a couple pounds of polyfill for an extra dB or 2, and will probably be adding bass boost to the sub.
i bought it as a compromise. the original system was intended to be 4x12, but would have cost a couple hundred dollars more, so i originally planned on getting a $20 MCM 15" for a quick fix and to move as much air as possible, budgeted for the JBL upgrade, then decided i'd stick with it for the weight and space savings once i had the brainstorm on how to turn it into a rolling lightshow without having to learn how to "arduino".
what i really wanted, besides cheap components to get started with is durability, so 96dB at 8 ohm mains and a 4 ohm sealed sub (hard to find a sealed box friendly single tap 4 ohm with a rubber surround and thiele small paremeters!) should be a relatively easy load on my amp.
i'm not looking to hit 150dB, just have a nice and clear sounding system for bike events, tailgate parties and downtown on club nights. i just went riding with "loud bike 2.0" a couple nights ago, and just like the ride i took before when he played funk, people were going nuts downtown and that bike just has a pair of 92dB peaveys and a 100w pioneer amp that wasn't even cranking.
my system will be louder and cleaner sounding with my really laid back but quick titanium waveguides, punchy 8" mids, and 93dB 15" with several times more power. it'll get the job done seeing all you really need for a little dance party is a boombox. my "boom box" will also have a sound activated RGB lightshow.
if you're at all interested in the system (haters hate bikes!) i already have a thread for it i'll add a link for.
