Super Smooth 3 way system

[lduarte1973]

Hi , i want to build a 2 or 3 way system , with super smooth sound for my bedroom . 88/90db will be enough , to connect to a 100w amp.i´m looking for a proven design , not build something new.Passive Crossover (active maybe later).I´m looking for clean tight bass ( no paper woofers please ), super smooth mids (no paper ) and smooth highs ( silk domes maybe ? )

i was thinking of woofer 10" 8" or 6.5"
mid - 3" to 5"
tweeter 1" or 3/4"

budget is 500 €

How about this Dennis Murphy design?

What do you have against paper cones? Paper is light, stiff and can be well damped. Have a look at some of the Scan-Speak offerings - a large proportion of their range is paper.
I'm not criticising, I'm just wondering why you'd limit yourself from the offset.

What you are looking for doesn't exist.
But near 83dB : see Zaph|Audio

In a higher budget, it exists : PRELUDE

He was right, he knew what he wants. He wanted a super smooth, clean and tight bass. But that would mean also more fatiguing

The seas design is good but i was hoping to find a 3 way , the prelude has paper woofers not my cup of tea

i dont need deep bass , something like 50-60hz is ok , but clean and tight , no midbass ressonance i hate that

Perhaps go fullrange? The forum here will give you many ideas...An Alpair 7/10.2 should hit 50hz...

cheers,

I recall a conversation, which may have actually happened here (or not).

Someone wanted to build some speakers, and he listened to Hard Rock music, so by his logic he need rock hard speakers, such as aluminum. Hard speakers = Hard Music.

But that really doesn't hold up in reality. One presumes that one who listens to hard rock, wants deep warm bass, and that as much as screams paper cones.

I've got some CTS paper cone 12" bass drivers with butyl rubber surrounds, that after 25 years are still in pristine condition. And they still kick it out regardless of what kind of music I play.

And, as most know, there are problems with hard cone drivers. They tend to have nasty break ups outside their working range. Which means you have to cross them over low enough and steep enough that the break up region is hugely suppressed when you hit it.

Next, keep in mind that crossovers, as you all well know, are not brick walls. When you crossover at 800hz, the bass driver is still responding to signals at 8khz, they are just attenuated by the crossover network. So, a slope rather than a brick wall.

The point is, a good speaker is a good speaker, you can't say 'no paper' when for a given price, a given paper cone driver might best suit your need and purposes.

Personally, I think Paper cones do an excellent job for bass drivers, but I find them a bit flat for midrange and tweeter.

For midrange, I prefer dome or horn, but, even saying that, there are cone midrange that do an excellent job. To some extent a cheap speaker is a cheap speaker, regardless of composition, and a good speaker is a good speaker, regardless of composition.

I'm not sure what the final recommendation is going to be, but if the person is looking for driver, check out this link in the EU-Netherlands -

Europe Audio - Home page

I've never done business with them, but they seem to have a nice selection including drivers from Dayton Audio.

My advise would be to start searching out existing proven speaker design, until you find one that suits your need and your budget.

Trying to design a speakers from scratch, it a long hard and expensive process, and typically requires years of study.

And for reference, €500 is about US$720.
