I had today the “fundamental channel” plug in and was trying to listen it. As usually I do, I connected juts one single crossovered “fundamental channel” to a single amp and try to live with it for a while. It usually takes for me a week or so to fig...

[quote user="KLegind"]I had a look at the pic of your speaker just now - may I ask about the reasoning that went in to choosing a diffraction type horn?Also, your midrange looks like an open baffle type. What kind of back wave/diffraction management ...

Thanks, Kerry. It was interesting. I never used neither RCA1428 driver nor it’s clones. I heard them I think once at Oswald Mils. It was for sure a pleasant midrange but it was nothing else wothe attention in there, so it is difficult to say anythi...

Paul, one of the reasons I went for the Orelo was because it's as close to "plug 'n' play" as I can imagine a speaker system being. So I'm not very knowledgeable about its detailed workings. What I do know is this though...There are 3x 15" bass drive...

[quote user="morespeakers2"]I thought Romy being very familiar with the S2 and also familiar with the 288 could quickly simply state a few simple observations between the two or just be honest as say he doesn't know, doesn't care, or doesn't remember...

[quote user="Reno"] ok. maybe we have a different understanding of "electronic equalization". We do not use active (i.e. electronic) equalization in the amplification chain. There is of course some equalization in the passive crossover but I real...

Bill, when you were at my place I use two PP2000 running together as at that time I did not discover the effect. I was running my MF at -2dB and my tweeter at -1.5dB. As now I use one unit and I return back my MF and HF channels to the level as they ...

I see, this is very different question then you initially posted.
Ironically the subject was discussed years back what I was fighting with S2’s “fuzziness” at very top.
I still do not feel that there are any 'rule of thumb' in it, there are...

Vasyachkin,
I have different view about “modifying products” as any product is always implying something very generic but I have my own needs. Probably not “modifying” but adopting would be better but it is not the subject in here.
If you read my s...

Wow, 6 x 15" drivers (!!!); though the curved profile certainly imparts rigidity, I'm guessing this horn must resonate more than a bit (no bracing until the mouth) -- but I like this thing.
Interesting, the phase plug-like device...

Johan, I understand what you are saying. This is kind of James’ barn thread and if you do not mind can you share with him one thing, I think that many others, including me, would be interested to learn the answer to this question: What did you gain g...

Thanks, Eduardo, very interesting. The YL 75000 has no phase plug and 70Hz with 1” trout. It look to me like a conventional diver. Which beds a question: if to reduce compression with our classic drivers, loose plug off and reduce power then can we ...

Well, it unquestionably much better, still I am afraid that they are trying to spread one ass across two chairs; I will talk about it in the end. The change from what was before was around the frame and upperbass horn. It looks like the guys are tryi...

Dear Romy,
well the horns are actually not designed for HF. The intended working range is up to 5-700. But since we use low Q, only second order filters we want to have a rather large overlap in the crossover region and a fairly even pattern over ...

Hello Angelo,
Even though it may not be a good idea to use a phase plug in a straight Upper Bass horn, I did find the information educational, and just wanted to thank you for the link. Thanks also to Romy for his comments on the subject.

I am not a big fun of Dvorak 9th under Ancerl. I’m not big fun nether the orchestra’s balance nor the recording quality. Anyhow…
I do not think that that you need to worry PH-77’s accuracy of curves or the comfort to switch them. It looks lik...

Oh well I tried. I though I was clearly asking some easy questions about two similar drivers and the small details of what makes them sound different.
I obviously did not do a good job at this.I thought Romy being very familiar with the S2 and also...

[quote user="tuga"]I can't find a/the post(s) where you describe the advantages of using a 4 inch throat. Stereo-lab makes both 4 and 8 inch throat 140Hz horns but I don't think they could make an 8 to 4 inch adapter... [/quote]

Hi Romy Indeed you sound a little racist, but i think we all have our prejudice. Funny enough, i didnt recognize nor cared, spotted the horn with my eyes, went in and listened.Now, read this carefully: I listened to the system with closed eyes, for ...

MINGSU,"Time-aligned

A phase plug in J-horn? Hm, OK, whatever…
Dresden, what I find disconcerting is that you are talking about “design” without taking or thinking about your sonic objectives. That is all reminds me very much what the folks at diyaudio.com do. T...

hi maxx
Just found this by accident. Had similar problems in my K-horn when i started to use it higher.
I found out that the 8 Liter prechamber caused the resonance in mine about an octave higher than you seem to have yours.
