Full Range Pondering

[DaveCan]

I love the full range one driver approach as many here do also. For some, due to listening habits and music taste ,and or driver choice, the need to add a top to their full range driver, or a bottom, or both, becomes a desired goal and even a necessity..

For sometime I've been thinking the best and most pure approach is never really offered at all, there are some close examples but not really what I was thinking.

Here's an example of what I mean by pure, or accurate I guess you could say, and I'm thinking it may offer the best sound possible per driver choice.

Example: You purchased the extremely highly regarded DaveCan 6'' full range wonder driver a year ago The midrange is the best you ever heard and the price was reasonable, but!!! You want more sparkle on top and more grunt down low, what are you to do? Well I guess now you go searching for a tweeter and a woofer and play around, and things get sounding really good ,but never a perfect match, and how can it all match? different materials.... So what if the DaveCan wonder driver also made a tweeter and a woofer from the exact same cone material as the wonder driver, Bingo!!! So the wonder paper mix in my full range cone, is also in my tweeter and also my woofer, different weights but you get the idea.... Why is this not done??? Any thoughts??

Hmm...not the same materials but along the same lines

Sort of what I mean.. Let's use the really efficient 8'' driver you stated as an example from that thread link.. You want to add a tweeter and a woofer to that 8''er.. The 8''er is made from a special cone material that sounds really good, and is the reason you like it in the first place.. Now the exact same cone material is also used in the tweeter and the woofer, that's what I mean.... Different shape's and thickness obviously, but the exact same material... Dave

Also in your first inquiry about building around the ACG3SI, then the same material in that would be the same for the mid and lows, that's what I mean, exactly the same material etc.. Dave

[DaveCan]

Sorry for triple posting, but for me I think that given the right full range driver, the need for a tweeter is nil... So that just leaves the low end.. My idea of a perfect system for me, would be a full range driver matched to a low freq driver.. Imagine if the Feastrex D5nf were in your listening room and also a pair of woofers that were made from the exact same cone material as the D5nf... Same with a Lowther, AER, Fostex and on and on etc.. Dave

I wonder Dave....
I can't claim to be familiar with modern full rangers, but the Goodmans I now have, uses such a thin type paper, I doubt it would be suitable for a wide range of drivers....

I would expect other fullrangers also uses a very light cone...

Doesn't have to be the same weight or thickness as I mentioned,just the exact same material... Dave

There really should be no reason for using identical cone materials.
It ought to be a matter of fine tuning the XO's in terms of response and linearity, evt. also baffle step.......?

[Cal Weldon]

It can be done with aluminum, paper or polycarbonates, I think the reason it's not done more often is that different materials are better suited to different jobs.

[DaveCan]

Shouldn't it be easier or more successful designing a x-over for drivers that already share the same tone in the first place?

I wonder if using different materials for everything is just because that's easier to do ,than to really rnd what I'm suggesting..

In my mind I can't imagine a better tonal match than using the same materials.

Just to use Feastrex again as the model, if you wanted to add a subwoofer to augment the D5nf driver, how could a person ever get the same tonal match by trying even a plethora of other driver's that are made of different materials than the D5nf cone.. Sure there will be some that sound very good, but now try the Feastrex 15'' Washi paper sub(if they made one) and tell me that is not the best match of everything you tried to augment the D5nf.. Anyhow that's my pondering Dave
