Why?

[iceteebone 5,000+ posts]

Because his real question was why don't we discuss things of that nature. Mainly, IMHO, it's because most of the forum base 1) doesn't really care, or 2) isn't advanced enough to grasp it. Nothing about the newbies being "bad"....everybody has to start somewhere, and you can't fault someone for just entering into a hobby......but those kinds of questions just aren't going to be brought up very often.

Maybe talk the admin into opening a subforum (maybe under the "general discussions" section) for "advanced discussions".....like what SIN has.

ok i'll start a new thread asking what all that stuff means then i'll get flamed and told to search and when i search i'll find this thread, but i'll read is newb bashing and learn nothing and have to go to another forum to learn where i won't get bashed and come back to this forum and see all these threads about how this is a newb forum and nobody gets into technical discusions but yet nobody ever talks about technical stuff only complains how others don't talk about it. wow that was a hell of a run-on. i was kinda wishing you guys would explain what all this does, so i can go impress my friends with my new knowledge instead of posting three thousand useless posts. //content.invisioncic.com/y282845/emoticons/cool.gif.3bcaf8f141236c00f8044d07150e34f7.gif

Yes.

Alright, but if the information is there, in the forum... the 'less advanced' & members who could care less will prolly scroll through it eventually and might take note of a thing or two.

Nothing about the newbies being "bad"....everybody has to start somewhere, and you can't fault someone for just entering into a hobby......but those kinds of questions just aren't going to be brought up very often.

Agreed. Nothing wrong with being new or inexperienced or what have you. But not everymember of this forum is new, either. There are many a post whore here who have some technical knowledge. Also, members with but a few posts who know a thing or two. If it's brought up, and discussed amongst these members.. refer to the point above.

We all have things that we could learn.

rofl... great post.

Great points too, unfortunately.

*edit* I dont mean to say that this is necesarily a newb forum.

Like I edited in (apparently after you quoted my post //content.invisioncic.com/y282845/emoticons/tongue.gif.6130eb82179565f6db8d26d6001dcd24.gif ).....see about opening up an "advanced discussions" sub-section. Advanced topics can be discussed, and those who are truly curious can go investigate....and the topics (hopefully) wouldn't get lost as quickly for quick reference. Have the mods watch so that "how do I wire 2 4ohm subs to 4ohm" threads don't get thrown in there.......

i believe 90% of the poeple on this forums just want something that sounds good and looks good.

Sorry, quoted before the edit.

Two problems with that, as I see it:

1.)CarAudio.com has "forced induction & performance" sub forum before it has a "advanced topics" sub-forum... I don't think it is in the cards.

2.) I, personally, am not going to ask that the mods here have any more responsibilities thrown at them. I've learned my lesson about that.

...and 90% of this forum doesn't understand "it's all in the install"... but alot of these things would help.

sigh. theres lots for me to learn, mainly how all the paramaters interact with each other, and why... but i dont feel its my place to just ask *how*?

Why is it that there are never any threads about capabilities of a motor to control the cone @ xsus?

because xsus isn't related to the motor at all... //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

xsus is where the suspension's compliance has dropped to 25% of its at-rest value..

motor can only control the coil when there's plenty of coil left in the gap..

and if you design the motor to xmag past the drivers xsus... you end up with lots of broken spiders... //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

do you really think that an 8 layer flat wire coil can have a low inductance?

certainly.... length / awg of the wire determines inductance.. use a larger enough guage, and keep it short.... layer's are irrelevant..

there was at one time, a prototypical coil floating around a certain buildhouse, that was 16 layers, of 20- some awg flat aluminum with a very short winding length, measured quite low inductance wise..

then you can also toy around with shorting rings, and copper sleeves to lower inductance too...

would thermal vents in the gap or in the top plate do a better job of wattage dissipation?

the best cooling method out, IMO, is the inter-topplate cooling method used by Resonance Inc. followed closely behind by a sealed pole / interbasket cooling method, as seen on several of RE's drivers...

in fact, going from an open pole, with interbasket cooling, to a sealed pole with interbasket cooling yielded thermal handling increases of over 120%...

why aren't there 6" voice coils?

because tooling parts to accomodate them would be very pricey...

-or-
ah.. nevermind.

ah come on.... I'm playing !!!!!!!!!! //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif//content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

I dont know I think this forum is great. I have learned so much about speakers and subwoofer and creating the right boxes and head units and so on. People go on this forum for many different reasons, many of which just want to know what is a "good" product. As one of you have mentioned before, many people dont care how it works, as long as it sounds great and looks good. Even in threads which may contain no actual content of advanced topics I still learn a lot. One thing Ive learned is the comparison of subwoofers. I really have a perspective on what different model subs can do. And then we have our threads where you knowledgeable folks would argue and get very very detailed about a certain products' build quality and potential abilities. There is one certain thread I remember where the RE SX was argued to be actually louder than the XXX. I learned much from those arguements and comparisons. I just wanted to say that I love this forum and it really is a privilege to have this kind of knowlege at my finger tips. I just ordered two SS RL-i subs only because of what the people here have mentioned about them. I was looking for pretty strict SQ subs and and this forum led me to them. Its a scary thought to imagine what I would have in my car right now if I'd have never stumbled upon this place. Some Fosgates maybe?

If you want to see a certain type of discussions here, post them yourself if nobody else will. //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

I try to check out all the big forums at least once a day..

or somebody can catch me on AIM.... bigbassloyd if they have something out of the ordinary to ask...

if I can't answer it for ya, I'll simply lie... and nobody is the wiser... //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

there was at one time, a prototypical coil floating around a certain buildhouse, that was 16 layers, of 18 awg flat aluminum with a very short winding length, measured quite low inductance wise..

Layers are very relevant. 4 layers of 18awg copper wound into a 1.2" depth (on former) is going to take more to get moving then a 2 layer 18awg copper wound into 1.2".... Layers = winding length to an extent.

the best cooling method out, IMO, is the inter-topplate cooling method used by Resonance Inc. followed closely behind by a sealed pole / interbasket cooling method, as seen on several of RE's drivers...

Then why do so few 'spl' drivers not tool the same venting? the Resonance designs havent chaged a whole lot. The most current motors are not very old... before that the 450oz motor hadnt changed in years. Why you think the sudden swing?

because tooling parts to accomodate them would be very pricey...

But as Squeak pointed out, there are drivers out there. This question was really tied to the Le question above...

ah come on.... I'm playing !!!!!!!!!! //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif//content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

Yea, I cant see you answering closed end questions all day long. You've got better thiings to do I would suppose...

you my hero
Loyd L.

Yea, thanks.. ...You complete me.

This thread is very informal. I like it!

Muchos love to everybody!

Handjobs all around, courtesty of Squeak.

um.... length.... not layers... layers = not the issue... length of wire = issue

200 feet of 18 awg round copper = 1.2 ohm dcr, and will have the same inductance whether its wound one layer, with 254 strands.. which on a 3.0" former, yields a 10 inch winding length...

or 4 layers, yielding a 2.5" winding length

unless you do something like Bifiliar winding, but that's another story.. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

I'm pretty certain Resonance holds patents of their cooling method... alot of companies base their production on part pricing... and don't want to tool anything.. Resonance is a very cautious company, that doesn't like to stray too far ahead from what it knows works..
