People who read my site regularly know that I like pull of my ass new ideas and grand to them my own abbreviated names. Why not, they are mine own idea and I feel full inventor rights to do with them whatever I want. The new notion that I would...

[quote user="rowuk"]The more "DSP
corrections" that we add, the worse things get. In addition, DSP time

[quote user="martinshorn"]i see the words time alignment quiet often in this forum Which is a good thing. But can you show a graph / measure that says what it means in a result?Or do you just mean the woofer is standing next to the mains?Cheers Josh ...

Since the “no tilting rule” is one of the Macondo’s Axioms: (#2 - “All channels shell have strictly parallel axis”) then I would like to defend it.

I have with bass not a problem but dilemma. I do not have problematic bass but I have a dilemma how to supplement my current bass with ULF without affecting my current bass. Adding ULF defuses my current bass, renders the bass phasing to be more ...

Anthony live in AU and they have for themselves a site where Anthony regularly
post the progress of his project. I do not post in there, I was banned from

Just to share with you with my ideas about the Scepter 500 clones. I´m not sure if I will use the w3801 bass drivers. I felt in love with Altec 416 and quite frankly I very much doubt that Onkyo would sound better or equally good. It surely doesn´t s...

I will be dubiuos about the slanted enclosure if not done properly, all drivers must be time aligned and since they are playing the same frequency, deficiencies in time alignment become more obvious. I made a slanted enclosure but with the drivers ...

I tried a highly modded DEQX on my horns for some time, we did all the time alignment with it, we used 1st order and 4th order xovers and everything in between, we used LeCleach adjustment for bass and all the other drivers we had it sounding for som...

Well, I may be one of the dummies here, but there are several things that could be viewed as "wrong" if sound was the primary goal:1) 95dB speakers and SET amps2) SET amps instead of DSET3) components assembled without a sonic goal - rather only comm...

The Martion speakers ignore time alignment among other things.. How good can the bass be when the overtones are not even aligned?...

user="kodomo"]I don't think you can align the tapped horn. My tapped
horn has a total length around 5 metres. To time align that with my other drivers,
its got to be around 5 metres closer than others. The only other solution is
delaying t...

[quote user="jessie.dazzle"]Romy, I'm very pleased to learn that you've got your Injection Channel done. I assume the above illustration is not indicative of the way you have the Tannoy Red aligned with regard to the other drivers, as it appears to b...

Most commercial speakers I have heard are not time-aligned. Some claim that a large part of the population is not "sensitive" to time alignment. That is rubbish. Most people have not heard properly aligned speaker systems so have no clue why their sy...

Romy & Dominik,Mingsu is a DEALER... more or less about business and money, did you really expect him to be a horn expert?
From Jeffrey Jackson:

Cat, Thank you for your time trying to help.I'm not engaged to my Accuphase though I do care about it.I read your comment on the ASP antenna and went to their site. In their tuner section for alignment and repairs they have amoung other tuners a ...

thanks for the good infoactually we are developing a full horn-loaded speaker the bass-bin is just inspired by Klipsch La Scala (just like Volti speaker) with curved sides. the mid-range consists of TAD 4001/Beryllium in Edgar wooden Tractrix horn an...

I do not advocate injector
on the ground. The way how I use my injector I high pass is aggressively, so the
ground coupling is not a requirement. If somebody use injection at lower
octaves then it might be a merit to do so but not in context of my...

I have just started thinking of something like this for midbass/ULF: floor firing one-eigth horn (TuneAudio Anima inspired) with the scanspeak array (in green) attached to the side.There is the obvious problem of time alignment, but I can see no wa...

If you read Danleys paper, you see that the lower you go in frequency, the more this device turns into a direct radiator. He just vents the HF drivers from the throat, more or less optimised, the midrange drivers a bit further out and the LF drivers ...

[quote user="Romy the Cat"] I do not use compression driver
for bass channel. I would like to have my system esthetically balanced, to get let

way time-aligned it. So,...

The coherent wave phase plug gives time alignment across the full width of the Be diaphram,, No other phram can do this.....

I am not sure what you say. You said that you are able to do time alignment by by-ear listening “a well known single instrument recordings, then to more complex and textured recordings”… Can you tell me what you are listing for while you are doing it...

Wojtek,
I do not think that Martin has any time alignment strategy. You see, the necessity for time alignment is a basic fundamental principle, and particularly in horns that spin phase like helicopter. However, in many instances the horns are juts ...

Thats the kind of stuff I was hoping for. I appreciate the help with this, there seems to be a scarcity of horn related discussion on the web and its proving hard to learn the ropes.One other unrelated question that could save me a lot of trial and e...

Hm, and you used 12” driver with 4.8" x 4.8" thought? With you look for 6”-8” driver and Fs drivers. I know it would be very hard to find them with near 100dB sensitivity…
