You know, I could be wrong, but I cant be certain that this WWWWMTM with your Daytons will be any better than your own first design

Now a 2.5way seems possible, maybe it could work with your own first design...well, maybe it has changed a bit


I dont know if this is what you have imagined...hell, maybe it could work, looks ok to me...maybe even better than the other

We could agree on everything

Regarding listening to music...it seems I can only really enjoy music completely on my own...somehow it doesnt seem to work with others present, no matter how good friends they are :bawling:


😀 😀 😀

Please , explain better your situation: are you saying that others presents disturb you in psichologic way thus you are not sure to hear good as like you are alone?
Or the others symply do not appreciate the sound of your system as like you appreciate it?

Cheers,
Paolo

Like I stated before my number 1 objective is to get that sound that makes people second guess themselves weather its the speaker or some one in the room. I love this effect and have only rarely heard on occasion with certain material. I think it mainly involves imagin and the tone of the speakers?

Hi Justin,
Basically you need the speakers total desappearing. I agree, but it is very rare!
My suggestion is : keep the speaker as simpler as possible.
Tweeter+midwofer +(multi)active SUB.
Neo8 pdr crossed very easy L2 with one RS180 at about 800Hz.
Slim tower, Neo8 at ears height, closed box ( for both wf and Neo8).
The satellite have to sound correct alone, then kindly add the subs ala Geddes. RS180 unfiltered.
Do you have basic measurements instruments?

Cheers,
Paolo

Acoustic does change a bit with the number of persons present
There are issues like the chair
Some complain about their glasses
etc

And yes, other peoples presence does disturb my concentration, a lot

With other people I listen with my brain more
Listening becomes more like an intellectual process
Not good to listen too much with ones brain
And too much zapping

When on my own I kind of more like feel the music
Its more like I sort of float with the rythm, singing along
No concern about technological stuff, or how it sound, only the music matter
And no zapping

And yes, my friends love the sound at my place
They have never heard anything like it
But you are onto something as I does seem to make much effort in trying to find the right music to please my visitors
And I do want the sound to be very good, but despite my friends tell me its fantastic it doesnt really work fore me

As said, on my own I only hear the music and are not bothered with nothing else
And I dont do very intensive listening sessions any more
Im not listening fore special details
Just listening to the music, nothing else matters
Could be that regarding the technical stuff I have finally achieved teh sound I ahve longed fore my whole life, flawless enough to let the music flow effortless with no constrains...and Im getting old and wise

Another point is that my friends dont come here to listen to music, but to talk about things

🙂
 
Thanks for explanation tinitus, I agree 🙂

We know, making one system sound natural, credible, true, it's a long story. years and years of learning, practice and attempts.
And no guarantee about "total" satisfaction!
If you are at that point you have to considerate yourself very lucky😎

Just curious: what amplifiers and source do you have choiced?

Cheers,
Paolo

If thats the way, I could also suggest a 2.5 way with 2 x RS100 and neo3

Or 2.5way bipole with one RS100 and two rs125, and the same on the back...depends on your listening room


Neopdr is very robust. You can filter it with just a big cap also!

I am for simplicity but in the past I have had a lot famous brand speakers. Some of they was big,dipolar, bipolar, hybrid, ESL,etc, but I definitivily think they sound "wrong". Impressive? Yes, but not accurate.
Accurate IMO only littles top slim monitors in mid-field.
So two drivers are sufficent ( maybe add a sub)🙄

Cheers,
Paolo
 
I´m using a 4 way with active amplification and a combination of PLLX and speaker level 1st order crossovers. A couple of 12¨under 90hz per side plus a vifa midwoofer, neo8 and a supertweeter.
In my opininion the neo8 is not enough up high. Adding a tweeter that goes above 20khz crossed with a single 1.5uf capacitor is like night and day.
 
I´m using neo8pdr in monopole config. By night and day I meant the sound without the supertweeter is lacking, somewhat incomplete. This is obvious with any source material but more so with sacd. I guess the tweeter is on above 12000 hz or so.

I wont argue with what you suggest

Only, now that we know all those drivers are present, I am not sure about putting more money and new driver into this project, but rather think that he should use what he has on hand, play with it, learn something, and have fun
Anyway, I dont think he will get what he dreams of, just like that
Sorry, but we have to be realistic about it

But still, I do think an acceptable design could be made with these drivers, somehow

Either that, or try to sell the lot, and find a proven design to build
If its just about making a nice speaker to play nice music on thats the way
But if its about having fun, use whats there

But Im sitting here at the other end of the world, so not much I can do about it



Paolo, as short as I can, to not confuse the thread

Yes, I am close enough, so I guess I am lucky 🙂

I use DIY 50watt mono amps, Advantage I200 as preamp, Advantage CD, the old black ones, and a Luxman tuner, thats all...speakers are 3way with 2x8" SS modified, 15W SS dustcap lightly coated, XT21 Vifa modified

Have a very long project with DIY ribbons and a DIY 6"...and others coming...at the moment I am thinking about going wilder or take the simple road like you suggest, the former being more fun, the later probably better in daily use

Paolo, I understand what you say, perfectly

But actually I somehow have a feeling that Justin want the ones you dont like 😀

Justin like BIG speakers, but maybe he could do with just big SOUND :clown:

But I understand Justin, and in a sense I have the same problem, having trounble to make the right decisions, if possible at all...but thats how it is with folks like us, many ideas and desires :bawling:

:This is what I have pictured in my mind kind of. Only difference would be an eqaul amount of tweeter to the side of woofer, hence the crazy double Neo8's with a Neo3 or AC G2si in the middle to extend things a little more and mabe add a little air up top to the highs. With a row of rs100s mabe 6 for a close match in sensitivity. And then go really wild and mount a pair of the rs180 in push pull one facing up the other down in a horizontal small enclosure behind the long thin front baffle. The mid- bass could use the back wall for re-enforcement. It would be crossed over low enough 150-200hz so the omni effect wouldnt be to strong from the soun waves bouncing off the rear wall? Then I could still squeeze the active 10" sub into the bottom half with a small sealed enclosure and variovent. I know still just dreaming? Still cant get that NOLA BABY REFERENCE speaker out of my thoughts. Also noticed Pablo thinks the Neo8s dont go high enough which I have read else where as well. I have all the drivers and a bunch of caps and inductors and resistors to experiment with. I really think this is the best part of this hobby trying things that shouldn't work and sometimes getting lucky.

When dealing with the unknown I prefer to stick to the rules

Its only to tell that what appears to be simple and actually is easy to handle, often isnt that simple at all, if you know whats behind it

On the other hand what you want to do really is the most complicated design you can come up with, and it takes more than normal skills to make it work

I could also say that a complicated design is the easiest thing to come up with...but to make it work is the opposite, difficult if not impossible, because its flawed from the very beginning

The simple design is really the most difficult...but to make it work should be much easier, because its a sound and solid design

As when you suggest 6db filter and use high quality components
Well, it may work but probably takes a little more than that
Im sorry to say, but afraid your are heading down a long and very difficult road

But worse is that you probably wont get what you expect
On the other hand I am sure it will be both great fun and very frustrating

But sure, I know the feeling, its great fun to do the thinking, and it cost nothing, as long as you stay with that

So build yourself a nice "premade" design to listen to, and then have all the fun you like doing other designs :clown:


The design shown below should be able to make plenty noice
You should have a small but fair chance with that one

I was sure of that....🙁

Please, can you post a photo , I would see the baffle size/drivers architecture. Just curious.

Maybe you guys think I am old and deaf😀 It is not so.
My audiomethric test says I am "perfect". Thanks my God:angel:

And I have ALSO the BG Neo3pdr that I use in another 3 way speaker, so I know what highs are. Lionel Hampton is sufficent? Red Norvo Quintet?

Ok, come back to the Neo8+Neo3 combo. You have issue with CTC spacing even at 5Khz ( wher I cross my Neo3 with a 4"audax mid), to not talk about 12Khz!:hot:
So I have asked myself: why I have to "destroy" the midhigh to recuperate , maybe the 15 to 20 Khz?😀 Because this is what happen, been there , done that.
It is the same reason because 90% of the fullrangers guys try to ADD a supertweeter to his Fostex,Supravox,etc but come back with the cone ALONE. 😀
Choerence!

Forgot to mentionate that my 2 way is transient perfect type x-over.

IMO, if you want planar mid + tw have to look at the Piega concentric planars. Not a bad idea.

Anyway I have listened even the Piega, but my stupid modified Neo8pdr sound more natural ( maybe because swiss employ bad fourth order x-over, I don't know).
I have compared with many high end speakers, I am lucky.

Anyway tastes are tastes , if you prefer supertweeter ....keep going on🙂

Cheers,
Paolo

Hi tinitus,
You are right, but I have suggested to use a dayton RS180 that Justin has yet.

Another options is forgot the Neo8 and make a TMW + separate subs .
Neo3pdr, Rs125, Rs 180. a decent crossover and voilà!😀


Thanks for description of your system, I am sure it is a continue "evolution" from years ( and years) of genuine passion🙂

Cheers,
Paolo

I agree Tinitus, american guys like big speakers !:clown:

The right decision? It is simple: you have to confrontate your creatures in the same room with some regarded high end loudspeakers:angel:
I have not problem if one famous brand speaker sound better of mine. It is happened with Magico Mini .
Just leave me two weeks and I come back with one more better again!😀

Paolo

Ofcourse, its the obvious...maybe as a 2.5way

My primary goal with all my suggestions has all along been to keep it 2.5way

I have a project with 18" woofer and 12" midbass and CD/horn running in 2.5way...we will see if its possible

Any reason to prefer RS125 over RS100

How about Neo3, RS100, 2xRS100, 2.5way xo + subs
