My god man you're a monster!
Seriously please stop copying my posts from other threads into this one. I am trying to stay out of it. I'll end my part in this saying you are wrong about me, and I prefer to keep it private (like you I suspect). I believe forums are for discussion and sharing information, not posturing or rubbing it in other peoples faces.
Dukk: thanks for the kind words in the other thread.

this man has been constantly misquoted just as he claims
so far on my first night on cca, i am not impressed everyone seems like ********

So many things wrong with this.... The fact is there is no use for zobels in active systems. The fact that YOU don' know this is mind boggling...
There was a huge thread about zobels not so long ago... here is an exert of why its useless in an active setup.... not that we couldn't implement zobel actively, because it can be done. The below quotes person is a smart cookie.
"...For example ... the all-mysterious "Zobel". All kinds of "magix" are erroneously attributed to it. Magix that are, of course, "lost" when you go active
A Zobel network does this : it compensates for the non-flat impedance of the driver, which helps the passive crossover behave like it's supposed to ... in fact, the Zobel compensates for a deficiency in the driver (non-flat impedance) so that the passive crossover can behave more like it's supposed to, more like a resistively-loaded crossover ... more like an active crossover.
We don't use Zobels in active crossovers (typically) because we don't need the compensation that they provide. There's no other "magic sq" associated with those Zobels.
Also ... a passive crossover and an active crossover will provide the EXACT same phase shift, per order of filtering. You don't gain any "phase benefit" by going passive ..."
A notch filter can, of course, be done actively... just like anything else you can do passively.
You loose.

if they change current changes and that changes the transfer function properties of a device
dog please correct me if i have misunderstood

I have a Sony 600W x 6 channel (F-L/Ri & R-L/Ri & center & sub) receiver, and it doesn't have pre-outs, just pos & neg wires. I want more bass, the sub is a Sony SS-WMSP80 10" 6 ohm (it doesn't say SVC or DVC) in a small ported box with a flared port. There isn't an EQ, there is a bass boost adjustable to +3, +6, and +10, and a different useless bass boost. It sounds horrible and there isn't enough out put. What's the best route for SQ & output for music/movies? Wiring options are 2 SVC 12 ohm or 2 DVC 6 ohm. I think the sub channel is 100W.

If I decide to stay, I will clear up most all issues of reasonable debate.
You're on the right track though...
Thank you for your supportive comments, it has been tuff to stick it out!

I have created a Poll to determine if I am wasting my time!
Rather than continuing in the same inefficient fashion, I'd rather simply move on unless by a show of votes, that the majority of you in fact desire to learn what you can from various posts that I up load etc...
The Poll will last 5 days and if it's determined that I am wasting my time I will move on.
I will be going dark (in terms of education) until after I have the results - cheers!

i just got to this post so i guess that you have had enough, i can't say that i blame you
as for my vote i'll have to think more on it. if your asking if we do in fact feel that your speaking to deaf ears, at this moment i would vote yes based on all that i have read to this point. but if your asking if i or others are actually listening and learning, speaking for myself i could say yes and would selfish vote no, hoping that you would decide to stay.
but no one can blame you for leaving if that's what's you decide to do because as i said before it seems like there are a lot of ******** out here.
i have been hanging out in another forum outside of cca for a couple of years and if you came over there i am sure that you would be treated better, the moderators seem to actually do their jobs over there.
i'd like to finish reading this thread before i vote.
Send me a pm if you’re interested in knowing the name of the other forum.
This seems like a tuff one, if you stay it’s bad for you and if you leave it’s bad for cca

Attention is what you wanted. And it's what you're getting, so your question about whether you're wasting your time, is rhetorical.
Who are you trying to kid?
If you simply wanted to teach, you'd write a book.
But you want to make a spectacle, instead.
If you really understood and valued sound quality, you wouldn't be in car audio. You'd be an audiophile.
Anyone with any understanding of loudspeakers, and acoustics wouldn't waste their time investing large amounts of time and money into a 'car audio' system that couldn't even begin to reach the linearity and transfer function of a properly aligned driver configuration, void of diffraction, baffle step increases, cavity resonances, back wave driver reflection time smears, enclosure resonances and drumming, and controlled off axis response, in a space large enough, and treated well enough, to mitigate comb filtering and standing waves, and increase the ratio of direct/indirect sound the listener would hear.
If there's any 'learning' to be done, it's to understand those facts that I've just mentioned, and stop going completely overboard trying to make a silk purse out of a sow's ear, with a car audio system that will never be anything approaching a great home audio system.

he does a lot more than teaching that was one of his old jobs and he is a well known audiophile and has been involved in manufacturing for long time. it's likely that you have owned something that he's designed. seriously he gave us a large list of things to narrow down who he is. I am thinking that he might be wishing that he didn't after how you all received him. and diem if you’re a high level guy like dog is it isn't likely that you’re as high he's into everything audio, just as he said.

he has written a text book more than one - haven't you figured out who he is it only took me 10 minutes on google after i read is brief bio.

A legend that lives in Markham.
Cool.
Why is he hiding his identity then?
Why are you?
Why jerk people around and play the enigma?

Not at all.
I've already said that I didn't.
Stop presuming and posting that I do.
It makes you look afraid of me, and desperate to try and attack me.
I've given technical reasons why all your expounding on technical knowledge is moot, in the acoustic environment of a car cabin.
Pretending those limitations aren't real, is amusing, and misleading.
Perhaps you're delusional, and you believe your fantasies about my emotions are actually reality.
Why in the world would I be anything but amused by your rambling?
Then you're not nearly as knowledgable about acoustics as you would like everyone to believe.
Thanks for making a few things about yourself, become even more clear...

seriously who the hell do you think that you are? if you work in the same fields as he does, if i was you i would hope to God that he doesn't figure out who i am.

Just a guy who knows a thing or two about audio.
Somehow, I'm not sweatin' it...
He's 'nobody' important.
Important people don't jerk around an entire forum, like he has.
