Is this the ATC box?
yes it is....
i have never listened to the big genelecs but i believe that the atc is a better speaker.
if one compares the small atc with small genelecs i'd say the atc is a shure winner - but its also a bit more expensive...!
Re: Re: Inspiration
Hi Romy ,PTSOUNDLAB, all,
Just so you know where I'm coming from,
I used to have a mono 4-way, mostly on open baffles,
mid/treble on horns, played like that more or less for 3 years,
suddenly I wanted to try stereo again,
that included serious compromises in setups and amps,
building more amps now , as time and money permits,
will take time , tho, money is allways tight,
bass in open baffles is very addicting, though,
so......
Back to subject, I've had good experience with very over size
bass reflex tuned very low ( 16-17 Hz ) , equalized to be more or less flat
to what ever you need, this works ok with most pro 15" speakers I've tried,
YMMV tho, and since I've only used open baffles for so long now,
my memory may be shot.
Whatever.
cheers

Interesting,
From a certain perspective it is more or less attractive: it has 4-ways (the way it should be) and uses a fairly small floor-print. However, from a deferent perspective behind all this “external attractiveness” there are some issues that unavoidably degrade the sonic values of the entire project. Just to name the few of them:
1. Ported bass with all its miserable consequences…
2. Inability to use in this configuration a first order low-pass filter in the LF section….
3. Limited radiation pattern of the MF….
4. Negative positional excursion of the MF driver relative to the HF driver….
5. Presents of an auditable horn’s curve in the upper bass section.
6. Using the 2446J driver in the 300Hz region where it dose not sound good.
7. Use of a high order high-pass filter at mid-bass
8. Physical bind of the LF with the ported MF section
9. and so on….

Sound like a wonderful system. A TRULY full-range, properly assembled mono system is THE very serious installation and it is very close to an ultimate capacity that audio reproduction could yield.

I know where you coming from and where you going to. Unfortunately in reality the demands and requirements for the mono and stereo installations are quite different. I personally (having 4-ways horn installation) as many times I was trying to move to an integrated mono installation I always failed dramatically because the mono or stereo was sacrificed for the sake of each other. If I may suggest you (without interpreting what I mint) then pay extra attention to your preamps in the phase-stereo world.

Yes, your memory is shot. Your open baffle should boil and eat any bass reflex on breakfast.

mono system is THE very serious installation
sorry, but i just don't get it.........

tbla, you can´t measure reproduction quality in numbers of channels....
even if industrie wants us to do so.

ok, i just don't have any experience with a mono setup - never heard one but the small radio in the garage......🙂
Taking under consideration the contemporary faulty methods of stereo recording and reproduction the mono systems are fundamentally more musically-capable then the stereo systems.tbla said:sorry, but i just don't get it.........![]()

romy, this is interesting, as i have my probs with stereo.
what do i do with my stereo CD? use only one channel? mix them? how?

The stereo CDs mostly are already screwed by the improper recording techniques. I personally do not do anything with them and listen them ‘as is’ in stereo. Even mixing them in mono will not illuminate the stupidity the Morons-engineers who differently compressed the volumes of the different instruments during recording, modified according their own barbarian perspectives the balance between the participants of the musical event and did many other their so-called “professional duties”… The REAL question is how to play the original mono recording via a stereo installation? This answer requires two separate systems… I do not have a dedicated mono system (perhaps I will built one), also I do not have any proper opera recording in stereo…. :-(

more random thoughts about the 2401
Ive found the 2401 and its variations somewhat enigmatic for some time. It has a long history that I think dates back to Westlake, although I'm not too sure about this.
I believe that George Augspurger (after his stint at JBL) and a few others had converged at Westlake for a few years and did a lot of work with this cabinet style. Like the picture I posted earlier I believe they are primarily intended for installation some what above ear level pointing down in a soffit that will extend the baffle.
The name of the other engineer who I think worked on this design escapes me at the moment.
I know Westlake is currently offering 3, 4, and 5 way cabinets of similar design.
In a thread about 6 months ago Jocko expressed some serious distaste for the horn loaded monitors favored by recording studios, I never asked him, but have been curious if this is the genre he was refereeing to.
If anyone can untangle my fractured understanding of the history of these apparently related designs, please jump in and set me straight.

Hello all,
thank you for all these informations.
Slowmotion, yes I think I will certainly build a sato, but it's a hard job and I think I will need a long time. I have schematic and a friend work good with wood. At this time I have an apartment and not a house, this project is for when I will move.
At this time I use a self made speaker that is an open baffle with Fostex Fullrange and Fostex super tweeter put on a bass box with high efficiency pro woofer. With this high efficiency loudspeakers I use a self made 40W KT88 class A amplifier and a solid state for basses.
My two references listen Pink floyd "dark side of the moon" sacd and Rolling Stones "Stripped" cd sound very good on it.
But I think that when I will have more space in my house I can use horn and 4 ways, certainly with 2A3 or 300B mono blocs and tube active filter. So if someone have a good schematic of 2A3 class A (between 8W and 20W) I will be interested 😉
"Cordialement".
Pascal.

sorry to make you wasting time
Sorry to hurt you Romy, and sorry that you waste your time with me.
Maria Callas and opera music are so references for me, it's just more easy to me to compare "live" on some tracks. My tastes are numerous and open, for me there is not good and bad music, there is what we love and what we don't love. Exchanges is the best think to do.
I will not disturb you more.
Best Regards.

Re: sorry to make you wasting time

You did not particularly hurt me, but you declared your interests at the levels of AUDIO demands that ARE waste or time. It has nothing to do with taste, "good and bad music" or the personal preferences. It is a pure and simple TECHNICAL ASPECT OF AUDIO EVALUATIONS and someone’s ability to filter out the definition of sound reproductive success. In context of all those “sounds” coming from “Pink Stones” the Definition of Audio-Success and the sonic reference points drift to the DIRECTIONS WITH NO ANSWERS. It is still a great thing to do: an audio project is a good self-entertainment but it has already nothing to do with the REAL audio. Unfortunately the majority DIYer sit in the same swamp… :-(PTSOUNDLAB said:Sorry to hurt you Romy, and sorry that you waste your time with me.

PTSOUNDLAB,
Have a look a this forum, there is an interesting articles with a number of members using large format studio monitors similar to your design idea.

Romy,
I don't want to enter in conflict with you because I don't have your knowledge in "REAL audio" and I think that DIY world must be a world of respect and exchanges. All I know is that most of people want one thing, have a sound the nearest of the sound they have in "live", the more realistic with the more of emotions. For me, Audio is a subjective domain with law of accoustic.
Best Regards.

Hey Romy, Since it was clear a good while back that this thread isn't up to your standards why not start your own "Real" audio thread? As you've pointed out- even when someone has a system that you approve of, you end up with a half dozen recordings at best that are "worthy" of your system- the caricature of the audiophile with 100k of equipment an 10 recordings comes to mind...🙄
The real audio thread would have my interest.
topics please :
- which recordings
- which speakers and how to build them
- which source , preamp, amp - and how to build them
- why?
this isn´t that much joke as you may think, this would for me be more interesting than clamping diode or 8 channel dolby diy diskussion.
