I need to tell you that for a few days I been thinking about
what is going on with my channels. The measurements and listening clearly show that
I need to invert R and L lowest against each other but my guts keep telling me that
it is pure BS. The...

T, you are mistaken if you feel that I do not understand what and why you propose to do what you proposed to do. Nothing is wrong with “Audio Pragmatism” as a phrase but I feel that is not really an appropriate way to approach to problem. I mean that...

OK, I have found the problem I had with my digital and
analog crossovers, now everything is consistent. It turn out that my contractor
why built for me the IB manifold confused the polarity of right and left channels.
I was not able to use the pha...

E-v-e-n-t-u-a-l-l-y!!! Eventually the new “fundamentals channel” horn sounds as it should being incorporated in my Macondo! The key was the second order. I really never drove compression drivers to their 500Hz as I always used upperbass h...

Romy,
I tried non-symmetric crossovers (freq and slopes different for channels) but had to go back to symmetric because the phase response sounded very wrong to my ears. I learned that I could get used to a bad fr...

My experiment with midbass channel last week was wonderful
in a wild position. It proved that I have enough gain to drive my current bass tower
from Milq. Also, it proved that using a small midbass in wild position and playing
with crossovers I ca...

It’s been some time since I seriously considered hi-fi
gear in terms other than sound qualities. But I did think broadly and
specifically in terms of “current” when shopping for big amps. I have heard
some bad-sounding amps that were said to h...

[quote user="Romy the Cat"]I think it takes around 60 seconds on my amps. I have 2 minutes delay for high voltage, so it all within the limit. [/quote]
That is good to know Romy. It was quite frustrating when I tho...

[quote user="drdna"]I would not restrict myself to the idea that things need to be a certain way or a certain configuration of the drivers or ports based on theory alone. I think it is important to ask what is interesting about the sound that the new...

Brooks Audio is a reseller somewhere in Utah, I think he is Ale Acoustic US rep. Utah is reportedly a some kind region in US between Massachusetts’ Tanglewood and California. It looks like Kevin Brooks is moving and he is selling his Acoustic Sys...

[quote user="jessie.dazzle"] Assuming you go ahead with the mid-bass horn project: If you decide to run the woofer towers along with the mid-bass horns, it is logical to assume they'll produce much of the range produced by these new horns. [/quot...

A few days back an audio guy from Mexico-city visited me from. We did listen some music, talk a bit about audio. As usually I interrogated him about the problem he hears in my sound. The people who were in my room know that I do it with absolutel...

Well, I was there, which is more than The Cat can say. In fact, The Cat never heard a complete WE system first hand, so I'll have to take that into advisement when the expected foaming-at-the-whiskers rant.I always wonder why people would giv...

Although all of it has no relation to digital crossovers but still:
[quote user="cv"] On a vaguely related note: I dunno if you realise this, but conventional (ie excluding horn or large area ESL) speaker systems, even if measuring flat amplitude, i...

A woman I met last weekend asked me a question: “What you do for own pleasure, Romy?” In response I ran with her my standard “talk to women” Feline Psychiatrist scenario but with all seriousness - the question how to name what I do is not so simp...

[quote user="Romy the Cat"]As much as caps in speaker
crossovers makes deference, so do they make in coupling applications. In Milq
the cap is light duty as the amp never goes A2 and the cap is not change the
polarity, still the coupling caps do m...

Chirag, First off all you have to define what do you want from them. If at this moment you’re looking for something within $700 then very next year, when you finish you medical school you will be searching in very different price range… :-) Now a lit...

[quote user="k100"] If I were to try to find a pair of ML2's that are older production, what years of production does this include? [/quote]
All ML2.1 are the new version of ML2 and they are not good as ML2. However, I have seen the original ML2 mar...

I would be interested to hear your reaction to the same CD ripped
properly on a CD-ROM drive rather than recorded from SPDIF stream. If
your transport is VERY good, they should be equivalent... but on
damaged discs, or with bad transports, the err...

Only so much can be gained from thinking about
speaker/amp matching in the abstract. At some point we have to decide what’s
most important to us, personally. I think the idea of a “comfort zone” for
given amps and speakers is objective to a po...

Jessie, I pulled posts from Macondo Axioms thread and encapsulated them onto a new thread dedicated explicitly to your project. I hope you do not mind.

thanks I have a few questions to ask if you do not mind:
1) Did you experiment with surface of the horns and a negative contribution of smooth surface to Sound?Smooth surface are fine don't waste my time on a trival matters.

Rowuk, a couple of corrections, but I am certainly not arguing. First, the dac outputs 1.25VRMS, or thereabouts...I am going to measure it. The 0.6VRMS is because I run it at -6dB into the Placette because for some strange reason it sound...

[quote user="Romy the Cat"]To me an “installation”
is a complex set of measures and arguments that converts a listening space into
sound expressive space. [/quote]
Of course it is, well said!

The visitors of my site who have read my observations about the CES 2005

We, horn people, when we see as some kind of horn outsider begin to spill his foolishness about the horns inhalations, we always feel that out territory was violated by a primitive brain who listen a box loudspeaker. The Absolute Sound, in its ...

kodomo, there is a thing that you need to understand. The
objective to have bass channels outside is valid but it is applied to a perfect
condition when you have unlimited width. In the situation like you’re the objective to
have bass channels ou...
