Hi Peter. Yes, I own Sigma speakers. They replaced my diy Orelinos. As an amp I use Bert's gain clone amplifier which seems to be very good match. God knows how many amps I've tested during the years...

Since I have not heard original Orelinos or Orelo i cannot say anything about which is "better". They must have their differences since the bass section is different between the models. Edit: Also Orelo and Orelino have active horn section if i am not mistaken.

Thanks Peter, interesting as always.

I am not going waste anyone's time talking about my diy Orelino since it it has nothing to do with the real Orelino. What you said is true, I did not achieve the sound what I wanted by going diy. It is too much of a compromise. The baffle resonances, filters, all of it. That is why got the Sigmas when I got the chance. I never got the filter right by my self so I really understand your point.

Before my next statement I want to say that my system is not perfect. It does not have the magic highs like Acapella ion tweeter has. It does not image 3d like some smaller speakers do. The sound does not have the coherence like good full range drivers have etc.

But it does represent music realistically in my opinion. The reason I listen so close to the speaker is because only then I get to peek into the recording, only then I really feel the music, see the performer in front of me. In my room only then i get the feeling and the sound what I need to get satisfaction out of hifi system - it is funny since once a hifi retailer in my country told me it is impossible to achieve the sound I am searching for when he asked what I want.

I have not heard Orelo or original Orelino (I would very much like to) but I am sure they do music very very well. To my knowledge there are not Orelo or Orelino owners in my country Finland.

First time poster here. Hi all!

I have owned Orphean horns for years. During this time I have tried several bass setups. Best of these is Sigma (made by Bert)  and second is  my diy Orelino with three 12" Beyma drivers.

If you have a perfect room you can skip the rest of my message...

My advice for those who struggle with the sound quality is to move the speakers away as much as possible from the walls. And start to listen at close range.  And I mean close. When I realized that only then I started to hear the speaker and not the room. You'll know when you got it close enough, trust me.

From the speakers I have 1, 5 m to side walls and about 2 meters to the front wall (the wall behind the speakers).

Also the room in my experience is better to treat with diffusers. Maybe with bass traps for the problem frequencies.

At Bert's place the listening distance to the speakers was longer and somehow there the room did not affect the sound. So I am not saying that close distance listening the best choice for every room.

Just my 2 cents.
