[QUOTE="req, post: 2712976, member: 555713"] how about you dont talk shit [IMG]//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif[/IMG] here is the deal. different woofers have different thiele small paramaters. they have different free-air resonance. and they will play the frequencies you are supplying them... differently. strange concept, no? so here is the thing - when sub A plays 60hz, it might have a shitty transient response, and not hit the 60hz note exactally how 60hz should. sub B may have a better transient response, and play the 60hz note on key. now, the different waves comming off the cones, being different distances from eachother and the listener more likely than not will have out of phase output. meaning that the sound waves reaching your ear wont be the same frequency, the same wave amplitude and "phase"... i dont know how else to explain the word phase lol. when they come in contact in the air, they can hit eachother and negate the vibration of air molecules. this is called cancellation and will basically negate the sound, or make it muddy and aka sound like shit. unless you measure placement with a ruler to get the subs in phase, and do all kinds of other shit with the crossover networks to make the different speakers play the different frequencies so this does not happen, it will have very low performance compared to more simplistic setups. yes, i have had friends with systems who had done this, that i "fixed" for them. and yes, it sounded a lot better. i cant tell you weather or not to do that kind of installation. but hell. i would never have one in my car because it would sound like asshowle [IMG]//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif[/IMG] i think the majority of knowledgeable people will agree with me. and hoss. it is just a bad idea. but go ahead and waste your monies [IMG]//content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif[/IMG] [/QUOTE]
