Can anyone explain a bit? Orelino-Orelo?? Did not know there were two different speakers.

And this MKII what does that mean.

 :)

First there was the Orelo MkI, then the Orelino and now we have the Orelo MkII.

The Orelo MkI was demonstrated 2 years ago at the xfi show and is still my reference  (a bit tall for most), last year I've launched the Orelino as a way more domestic solution and now we have the Orelo MkII which is something in between.

Although, completely revised making it a new design with new features and better performance within the given possibilities. The Orelino following most of these developments and is now basically the "Baby" Orelo MkII and should be named Orelino M2 actually.

References for the Orelo MkI and Orelino can be found on this forum as well...

With the notion that the word of the Master counts ...

I realize that I started this board and its first post right out of the blue without too much "real introduction" because it would have been a too formal thing in my view. So, this introductionary post was the 9th version of 8 others which were 4 times longer (Bert knows the last of those) and it just got too long to my thinking. The first version I already created last September and/but the work has been so enormous that we only knew what would come of it when it was really done. And this was around "yesterday".
Now it is also more genuine (just real life) instead of commercial talk. At least that is my own opinion.

The history of the naming went more or less like this :

The Big Orelo is the no-nonsense speaker

(http://www.heartprofit.com/www/transfer/graphics/forumxx/Big Orelo.jpg)
Designed with "no limits" but really large and 4x15" woofers. It can be auditioned at Bert's place.

This is a passive speaker regarding mid-high, and the bass is active and comes with DSP.


Then a more commercial version was developed - the baby version of the Big Orelo :

And we named it Orelino.
Easily fits everybody's room and the top horn's middle is at 1m25 / 3ft8. Contains 3x12" woofers.
Can be auditioned at Phasure hence my place.

This is an all active speaker with separate/dedicated amplification for bass, mid and high. Bass can be controlled by integrated DSP.


In the mean time we also tried to turn the Big Orelo into a speaker that would fit people's rooms but which would carry the same specifications;
It was named Orelo MKII :

(http://www.heartprofit.com/www/transfer/graphics/forumxx/img_0479a.jpg)
The Orelo MKII has been a "hobby" of how to squeeze all into the smallest size while maintaining the efficiency of the Big Orelo (all Bert's work) and it contains 3x15" woofers.
Can be audiotioned at Phasure's.

The "efficiency" as such comes from a very large part from the way the DSP for the bass can be tuned and which has become a sort of obession for myself and now resulting in a straight to 19Hz (+/-0.5dB) which of course is outrageous for an open baffle design which also denotes the beauty of the "most open" bass which is totally real and not a super distorting subwoofer (you'll only know the difference once you experienced it).

One of the explicit design elements of the MKII is the height of the throat of the horn which here is 1m35 / 4ft1 and which allows for off-axis listening at all times (you'll always be under the beam somewhat). This in itself now allows for any toeing desired which now thus can be "straight" as well, while still listening off axis.
The MKII too is a full-active speaker with the same amplification and DSP as the Orelino.

This is not all, because both the Orelino and Orelo MKII come with this :

(http://www.heartprofit.com/www/transfer/graphics/forumxx/Orelo Controla.png)
which looks like a simple picture but actually is about a crazy wireing scheme without degrading the sound quality and which allows for external amplification and even anticipates future full DSP options without taking out the soldering iron.

There is still more, but nobody likes too long posts ... ;)

Really nice  :ok:

Speaking for myself, I'd be more than happy to have one of your really long posts on all this.

The more I hear about these speakers, the more psyched I am to have mine here. It seems Bert has really put some serious effort in getting things where they are (with more than a bit of help/encouragement from you of course). Well done!

Mani.

Wasn't sure where to put this, so maybe it needs to be moved at some point...


So, any thoughts on the sound you can share with us?

Mani.

Sufficient thoughts Mani !
Share them is something different; first a few more other general subjects.

But yes, of course ...
Peter

Hey Peter, here's what you said about the Orelo MkI speakers at X-fi 2012:


In terms of SQ, how much of a compromise are the MkIIs over the mighty MkIs?

But I understand, more general subjects first - I'm really enjoying learning about the more technical aspects of the speakers.

Mani.

Hey Mani,

Hard to avoid *that* question, but not so easy to answer ...

I saw Bert write that the Big Orelo's still are his reference. He can do that at his will, and I can say "oh no" at mine, but the least I should say is that we are not able to compare. It's also "nice" to see that when Bert made his statement about this he actually never listened here plus that after that statement we applied some last anf final improvements to the MKII (and he again never heard them after that). On the other side of the coin I listened to the Big Orelo's several times at Bert's and they sure improved too over time, just as that they will have improved over the last change to the MKII which Bert will just apply the same to the Big Orelo's (because it can).
Lastly our both rooms are not the same, so what to say.

However ...

Looking at the merit of your question it is 100% sure that what I have playing here now is a super improvement over what the Big Orelo showed at x-Fi 2012. But that already counts for the Orelino. And to make it even more complex or incomparable ... What happened to the Orphean horn for amplification and what's related to the efficiency (from 115dB to 118dB) is a change with impact you can't imagine, and *that* was never applied to the Orelino yet, hence I never heard it from "her" (yet).

The absolute sound as how I perceive it is still for another topic, but I already know what difficulty I will have at describing it. But we'll see soon what I can make of that description.

Regards,
Peter

Hi Mani,

Focus, this is something I always pursuit. Sometimes a big wide stage with music anywhere in your room is pretty cool too but that's mostly a free bonus when you have a big room supporting that as long as the speakers are able to fill the extra volume of course.

Peter has a BIG room, mine is moderate are relative small and I can imagine why Peter likes his setup more simply because of that.

My system is therefore more intimate, dreaming away on the couch listening to my favourite music but sometimes I want to have that big stage as well.

The main plus for the MkI's is their ability to focus more precise with the extra set of woofers on top. This creates a virtual center for the bass similar as the point source acting mid-high horns. All sound is basically coming from one single point, the main reason why I always liked full-range drivers in the past.

The extra bass drivers give more headroom (not really needed in my room!) in the bass with fewer vertical standing wave problems as a bonus.

But didn't Peter tell you that there is also the option to have an extra bass section on top of the Orelino and Orelo MkII?

At extra costs though and if you didn't know then now you do! ;-)

Bert

LOL LOL LOL

Really ...

As "dry" as Bert here spits out the possibility of this extra section on top, he told that to me too and he is even serious about it. So envision :

First we try to make an Orelo MKII which performs as good as his father (big Orelo) and when that's all done someone comes up with a "hey, you can add another woofer section on top of that if you want !".

But might someone really want it, technically the reference level (no sub-low audible distortion) of 88dBSPL will go to 94dBSPL (at straight to 19Hz). Not sure who would need that, but in the end it could be about a very (very !) large room.

Peter

I'll stick with my MkIIs, sans extra bass section, I think - should be more than OK in my room.

But if I had a much bigger room, rather than going for an extra bass section with the MkIIs, I'd probably just change my order to a pair of MkIs. But I suppose it's good to offer people the option...

Mani.

I would! ;-)

And serious about this too because it is not just dB's, think about even less distortion at the same 88dB (not sure if you can hear that...) but do not forget the d'Apolito configuration creating an ideal point source.

But BIG indeed and think that the Orelo MkI is a system I've build solely for myself without thinking about future commercial options. Therefore the Orelino was born and the present Orelo MkII which do perform outstanding as well where both could become some sort of MkI too with an extra bass section on top.
