After a few agonizing days I think a have decided for a provisional
solution. Listening and thinking about
options on a table and my current desire to invest time and resources I went
with 6+2 direction.
I have order 4 separate relatively-sma...

My feeling about perfect listening chair has altered lately – I need another sit at my listening chair, so it kind of becoming a listening couch instead of listening chair. As much efforts I spent to explain to my girlfriend about time alignment and ...

These days I am traveling frequently and relegated to listening to music via headphones and "portable" sources. I will briefly post my brief journey as a personal log. It might provide a starting point for those who might find themselves in the same ...

It wound up taking 9 weeks to get my re-built cartridge back from/through the Ortofon DK/USA consortium, and then I let the re-built cartridge just sit there in is box for another 2 weeks. When I finally went to re-mount it, I managed to snap a ver...

Looking at the drivers, and the range of adjustments, it appears that Wilson have done some things that make more sense than usual, at least to me. The MTM drivers can easily be set for "time alignment", which should help to cope with Wilson's "noto...

A few days back I visited an audio person who demonstrated to me his experiments with extreme lateral deviation of souses. Regardless if I agree or not what he was doing or trying to do the demonstration has an unexpected result. One day I was driv...

[quote user="Blaukopf"] First, Romy describes his horns as spherical. Later he names them tractrix. Are some of the profiles of the spherical wave profile? [/quote]
Yes, they are spherical, wish means not rectangular. ...

[quote user="Murataltuev"] 3. GOTO
SG-146LD in 46horn 50-400Hz
I've added 0,7m length to 2m horn, so now my
mid-bass horn has 4" throat and 1x1m mouth and 2.7m length. [/quote]
4" throat into 1x1m mouth…hmmm, you hardly
will be able t...

Spent great time and with happy with result. Not the results
are so spectacularly good but the playback is back to be operational that I was
missing for a while.
Starting with films. The damn OPPO has not enough output for
my Milq. I decided to...

[quote user="Paul
S"]Yes, insane amounts of money are wasted on "exotic" cabinet
materials and construction methods, for instance. And the misguided idea
of keeping it one narrow stack per channel does, literally, compromise the
sound, as does t...

As we are looking for our new home I am slowly simmering in
my mind the ideas about new midbass horns. It is not that I am short for ideas
but I am not sure that I will take my family on a bumpy and costly ride to build
new horns. One way or anoth...
|
|
Yep, indeed, it looks very nice. The 8 sections of bass line
array look visually slightly overweening but I think when you put the upper
bass horns in place it will visually balance the things out. I feel some sort
of envy to the way how you plan ...
|

There are some questions that I am looking answers and I do
not have a firm position so far:
1)
How the quality of reverberation channels speakers
and their amplification impact sound or the depth of the psychoacoustic trickery.
2) ...

If there is one thing that I have learned in life, and heard many times, is that making a mistake is not a bad thing if you learn from it. In addition the lesson learned is just as valuable if you learned it from someone elses...

I do not mean to be negative and criticize Romy, but he is wrong on surround sound. It is the implementation and not the concept which should cause vomiting, like with the vast majority of two track recording which are unlistenable. With the rig...

user="martinshorn"] What Klaus also highlighted, is the importance to
him to unlimit dynamics - in order to achieve the most live-alike sound. First
of all, he noticed that Goto pleases him the most with uncompressed transient
attacks more...

Yesterday I have a great listening time. I sent Amy with twins
to her parents. I put Thomas to sleep in his room and as he woke up I set him
to watch his Caillou for hours and I went to my listening room to have nice quality
time with my playback....

I want to share what I feel is a good application of an injection channel, as introduced by Romy. But this is different and also useful and i can tell you it works and very well. Of course, I do not recommend to use this application in the same exact...

The kids are growing up and twins sleep fine and walk already.
So, the Bessnow’s household is calming down, a live-in nanny for sure helps…
With more time at my heads I am trying to finalize my playback in our new home.
I spent a few hours today t...

What will be your suggestion for upper bass
channel using compression driver ? [/quote]
I do not use compression driver
for bass channel. I would like to have my system esthetically balanced, to get let
say 120H...

[quote user="Murataltuev"]Is any
technical background behind the statement that 4" driver can't
operate in 300-1000Hz because resonance is too low ? [/quote]
Well, you need to define what does it mean “can't operate”? Anything can operate anywhere...

[quote user="Paul S"]Audiopax/Avantgarde: This
room also had “good” sound, despite the tweeters were placed nearly 2’ from
time alignment. Maybe they calculated the distance and figured out the exact
point where the tweeter “came back into phase”?...

user="Murataltuev"]I did some experiments today again with GOTO in my
existing horn and it is obvious for me that I need different horn for GOTO.

To argue that time alignment is unnecessary is to go against a very basic feature of the auditory system: sound location from phase information. But if so, then the effect ought to be frequency specific, with a much lower magnitude ...

Hi Romy,Well, this is my (and my dad's) first horn system so we're learning/building one step at a time. Our motivation is simple, to use horns as low as possible.The very first DIY configuration was:TAD ET-703TAD 4002GOTO 505TTTAD 1603 Woo...

I'm following with interest the thread and must say that I'm baffled: Goto's "instructions" are - SIMPLY said - a mix between non-existent and wrong... I love what Goto's did in my system... BUT I think I did more with "my own" care, "my own" taste, ...

…but there are a few considerations that I would like to stress.
1) The ULF pressurization must not impact auditable sound in any negative way. If it does then all bets are off and ULF better do not be used.
2) The ULF pressurization ...

[quote user="T3GGG"]Romy, what is your thought on using a Tractrix flare on a Midbass horn, Fc 140HZ then maybe a Le Cleah horn above, say 400hz. To me this looks on paper to be the best of both worlds and avoids the 1metre plus midbass Le Cleac'h ho...
