Conditionally all imaginable loudspeakers in audio could be divided by two groups:
1) The loudspeakers where the pressure from the front of the loudspeaker isolated form the press from the back (Sealed enclosures, horns with sealed back chamber...

Hi, Ronnie.
I do not know what happen with emails, you probably should not use the world Viagra in there… :-)
Anyhow, the 25w/8565-01 drivers are optimized for ported enclosures. I porously never had them and never used them, so I could not be help...

While Dima is cooking the Super Zarathustra I figure out that I would need some test speaker to be able to observe the preliminary results. I would not be able to drive the multi-channel Macondo with a single full range amplifier, so I need something...

Hi Cat,
[quote user="Romy the Cat"]I used my typical “flash” techniques and discovered some leeks in that 50 years old enclosure. Sure it the leaks were there then it would be no “acoustic suspensions” and the driver would run further. So, fixed the...

I do not feel that there is any mystery in Wilson’s bass – they sound as they shall – like crappy ported speakers and it is very unfortunate in my view. David Wilson ether do not know what and how he is listening or know very much what he does but ca...

I would like to pass some observations about my MiniMe progress. At this point it is obvious that the MiniMe project will be a success, even despite the pain of the ass with multi-amping and some other setbacks. The MiniMe will turn out to be a good ...

Well, the license of think this way was given to me by one mini-monitor that I found to sound “promising” for the objectives that I would like to achieve. In fact not even the monitor itself but the bass driver, the drive that in a way was unique cha...

Bruce Edgar, the founder and designer of California-based EdgarHorn Loudspeakers, recently announced that he discovered a new relationship between his business plan and rules of physics. According to Bruce: “The physics of sound reproduction th...

[quote user="KOTriode"] On dynamic, the 6C33C tube showed its ability to go deep in the bass on Ray Brown trio recording of Soular Energy which is excellent for a 15W SE , the 845 amp can do better, but not by much, but probably because of its 25W ou...

It looks like Wilson brings WAMM back:

Well, what can I say – it is smart. A few "jaw-dropping
reviews" from the ordinary suspects and the new WAMM will be flying from warehouses

In order to increase the rotating mass the platters have to be couple much harder then my lightly-applied reel-to-real tape. When you stress platters horizontally harder it creates own problems that do have sonic outcomes. In addition, the only way t...

[quote user="jessie.dazzle"] In my case, the CD transport (which is no slouch) is soundly beaten. Apart from using it to make the occasional comparison, I have not touched the CD transport since unpacking the DAC.[/quote]
Jessie, I see an inconsiste...

[quote user="Brian Clark"]Have you experimented with transformer attenuators Romy?[/quote]Nope, I did not. I have two purely theoretical problems with transformer-attenuators.
First I did not see any transformers that can handle LF all the way down ...

[quote user="Markus"]There's no plasma tweeter on the Cessaro. The tweeter is the TAD ET-703. The HK owner has a gold-coloured horn for the tweeter, but there's no plasma driver. I'm pretty sure the horn on the Lansche plasma tweeter is a good bit la...

[quote user="Romy the Cat"]
Possible, with all my conversation about Mantis I do not remember I ever made any guess or assumption how it might sound. In horns, I feel I am qualified to make sometimes very bold assessments with very high prece...

Today, here in NYC, ESD had the biggest, most r e l a x e d, most natural, uncolored sound I heard—in any room. By comparison, in other rooms, there were ported loudspeakers that sounded more colored and obtrusive. Bravo ESD!

[quote user="Romy the Cat"]Yesterday I was working for a half day at the part of the house were my Altec 19 are sitting and just to keep myself entertained I set up the Altec 19 to play from my add-hog playback: Sony $30 DVD player, Yamaha C2A preamp...

[quote user="Ronnie"] Did you buy the Denon?I'm curious because Denon D-M31 (speakers not included) is on a recommended components list by the Swedish LTS (Sound Technical Society).

I got my pair of F120A by-the-book bookshelves a few weeks ago and yes, in the beginning they were very much "compressed" sounding. Things improved a bit over time, but the low treble (which gives instruments their "color") is still recessed. So I ...

[quote user="Romy the Cat"]
Actually the most interesting subject in physicality of ear to me is not the cochlea damping but the fact that brain and ear are liquid decoupled and whatever brain hears is transmitted through a liquid pressure wave. Of ...

I have some strange feeling about this MiniMe idea and I really hate those feelings. The entire concept of MiniMe was to have painlessly integrated with large-speakers mini-monitor with somehow “not to revolting sound”. However, as I go slowly along ...

When companies begin to produce crap (most of the today arms) then it is the job of various marketing whores, like Michael Fremer and the similar, to invert a theory that would justify the poor sonic results or to explain to the deaf audio-cretins ou...

Generally it is very uncharacteristic subject in audio: the destiny of audio reproduction. Destiny might be only with something that has its own lifespan. Audio reproduction is in a way an imitation and therefore should hot have own destiny because i...

I was rushing when I made the last post. Wanted to share a little more about my thought process and how I arrived at doing another large-scale masochistic audio project. Making a bass horn is a huge risk - the results can vary from exceeding expect...

[quote user="HookEm"]The reproduction does not seem natural... too far away from what I would hear at a live event (e.g., female vocalist). Sort of bright and fatiguing at times. I may not be using the proper terminology to describe it, but I do...
