Passive crossovers wouldn't radiate any significant noise.
Or cause any significant magnetic / capacitive coupled noise.

I agree - but I think "attack" is where people get confused. ]Attack [/B]- the rise time of the speaker - and in it's most extreme form (and only in that extreme form), that would be the sudden presence of a waveform, requiring the speaker to rise to response at a given amplitude. Ideally...

[quote="geolemon"]It depends on what you think of when you say "speed". Rise, or rolloff, for example? A waterfall plot is a very common way to show rolloff (or "sustain"). Impulse responses are created to show not just rise time, but overhang - in other words, if you h...

What is a Fourier transform? I found a Wikipedia on it, but I didn't quite understand what they were. It's a mathematical process to make a transformation from the frequency domain to time domain...I only mentioned it because it shows that an acoustical model of the loudspeaker "system" i...

So would the inductance be affecting motor control than? Edit: I guess what I'm asking is what determines motor control. BL would be the strength, but there must be more to it than just the strength. Motor force generated, as was alluded to in the Adire article is F=B*L*I Inductance does affect the...

Why do you think that 2 subs aimed at each other are going to be out of phase with each other, assuming the typical size of a vehicle?

Captain Pioneer-
That setup will be fine. It's very hard to predict particle density (sound wave reinforcement) in a car without playing with the subs directions.
