Wed, 02 November 2005 01:38 Quote: dude if you dont know what you are talking about then stop spreading bullshit. these forums are supposed to inform people not give them false and misleading information Yeah, I do,-> a. I hold a Physics degree. b. This is the kind of stuff that I taught to first year uni students for three years. As for bullshit, well I've been here and with this club since day one and have heard more bullshit than this thread!! and people need to be informed. Quote: EDIT: whoops wrong formula lol .. it can happen. Quote: Bass (low Hz) needs to be produced at a higher amplitude Amplitude is volume and yes it does play part in a waves energy. But what I'm talking about is two speakers at the same volume and hence same ampiltude, so the "Wave energy" and not the "electrical engergy" or any other fatcors, just the pure energy of the sound. Second point, put a piece of MDF in front a of tweeter and one infront of a bass drive, both cranking at 90db... You won't hear the any thing from the tweeter, but I'm sure the you'll still hear the bass! and what do you hear from outside a nightclub? BASS!! why? because all the high freqency waves have less energies and are absorbed, the low freqencies still have engergy and that's what you can hear/feel.Car a large syatem, windows shut doors closed.... Thirdly, conversation of energy, a good tweeter will never be rated at 300W RMS cause High frequecies at 90db doesn't need 300W of power to be made, High quality subs do, cause low freqencies have more engergy and need more energy to produce them. Quote: Johhny said - equal distance to ear = minimal phasing issues Yeah, this is the thing... the Phasing issues are so bloody small that that the human ear can't tell the bloody difference in the short distances within a car's enviroment.... so small that it's measured in fractions of a millisecond, this Quote: both speaker leave at the same time and will arrive at the same time is Phasing issue! So I think you need to learn a lot more. What about cross overs, and not the powered ones such as Audio control, etc, cause this can can be adjusted out on the really good ones, Just the Plain old Cap's and coils? These also cause a delay in the sound produced and create Phasing issues too, again, measured in fractions of milliseconds and again, the human ear can't tell. Even putting the speaker in in a slightly different offset in the location can cause this, so really a co-axial speaker is the best solution to phasing, since both speakers are in the same indentical place as where both sounds are produced and why they are not used in systems, another arguement... When I hear "phasing", I think to myself, "audiophile" crap. I was a very much and still am audiophile, more home rather than car's today. This is only jargon, like the word "Synergy" that is throwning around by marketing team would use just it to justify themselves by sounding intellegent. They only really get away with it becuase most people wouldn't have an idea what it means and it sound hip and cool! Quote: If you want a basic system, you do what you like. Sound is as personal a thing as your frilly undies. So true, Just get the Blue tac out and choose! [Report message to a moderator]
