Hi Romy,
I'm Autotech (Lukas Lewandowski) friend who manages technical correspondence and do design part. Personally I'm interested in all horn designs down to 20Hz and I do see some interest in multi-way horn designs from eg. Hungary. IMG_350...

Spend a few hour last night and have all the things connected and laid out in the way how I think would be “properly”. It turned out to be noise and elegant. I changed the location of the components to make the shorter paths for power cables and for ...

Here we go, I will be telling you that I am looking or that I have found the “best” cable to use for bass channel? Sound like a stupid thing to tell you and sound like a stupid thing to read at my site. Still, I will be obnoxious enough to insist...

After going through the anal pains of the Image Gallery upload (it is sohuge now that my browser slows down 10000x times loading it and it ocasionally kicksmy router out of this world; can we do something about it?), here are some picsof my assault o...

About importance of impedance curve and current delivery of amplifier i agree you but generally we have some numbers (watt for spl) for average condition.
Live or dead rooms and bass extension are also change the numbers .
My numbers come ...

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

[quote user="Romy the Cat"]You decided to go with mA or are they mV against 1R resistors?
I prefer the second approach personally and I feel that I can moderate the quality
of resistor and I can’t moderate the quality of the milliampere meter coil....

It took a LOT of time in CAD using what I had learnt from building the power supplies and then adapting it to match the requirements of the rest of the system. I have decided to mount the DSET on the horn stack and direct connect the speaker cables....

And The first thing I did was I grabbed the multimeter and started measuring what JJ suggested. I think we're on the trail of "something". I discharged all the capacitors in the amplifier and with the amplifier turned off, when I put the red tip ...

I will be making another experiment tomorrow and will try to install a new dedicated power line for audio. I say “another experiment” as the dedicated line that I installed as soon I move into the hour did not sound good, I have no idea why.

I had yes today a meeting with a rep from out local solar company. I am kind of greenish pussy and have a house with a big rood turned to south – so I was wondering to put in there a large array of solar panels. Massachusetts has a very wide coll...

Ok, Andrew, this is allergy something. I would highly advise you in future before you post any discrete updates, questions, and ideas about what you to inform about the holistic objective of your project, sort of a view from 50.000 feet...

[quote user="Stitch"] When you look at the data sheets, you see, that they have different Hz range with different weight. A reason why I added some more mass to my Micro which is sitting on a VP. [/quote]

I spent a bigger part of day today to finish the “End of Life" Phonostage, there were many things to do but it is now over. Done! Complete! Amen! I it closed up and sat in it’s permanent place.
A few observations looking back. First, I spent a LOT...

Dear Antonio,

An "F" type connector is provided exclusively for use with the optional Sansui FA-7.

Playing recently with setting up the new 6-ch Milq I again got an interesting feeling about my Fundamentals Channel. The in Injection Channel partially overrides some benefit of the Fundamentals Channel and I have a partial feeling that it would be p...

I have noted before that the quietly of sound that I’m getting from FM broadcast, or even from the regular FM transmissions of the regular CDs, is insultingly beautiful and not really compatible with Sound that I get out of my CD and LPs.

All that I will be saying are the subject of my own experience with horns and my personal observations. You shouldn’t agree and most likely you will not. That is fine with me. I have lot of reasons behind what I will be saying and opened for some cla...

Hello Rich,
I've done a quick modeling for a LeCleach horn Fc=100, and that thing is 2 meters wide and 1 meter deep !!!
Its double the width of other contours.
The conical flare is very nice but colored by the reflections from the mouth.

[quote user="drdna"]I have found the next obvious glaring problem, which is contributing to the muddy sound I described earlier. There is a mismatch between the two channels. The right channel is very slightly softer than the left with a ...

[quote user="TonyB"]I disagree. I think it depends on the turntable. If I did not try it on MY turntable, I would not believe. My Verdier uses a DC motor "sloppy" mounted on grommets. The drive is linen thread. I have tried silk, different threads, 1...

I did an interesting experiment today trying to learn if those Melquiades driver tubes have even gain. The Russian tubes are notorious to have very widely spreading specification, so….
I took 14 6E6P. Some of then were new, some used and some violen...

Ok, how to start. First of all we have to understand that out subject of attention will be a region between approximately 80Hz and 500Hz or something that shape the fundamentals of the “melody range” within your playback. Search my site I have writte...

Well, Jim, it is time to say “Oops!” I told to myself do not make any posts early morning unit I eat a bagel but this mooring I disobeyed the rule. Anyhow, I do not know how I come up with 28.5V RMS. Defiantly it was peak-to-peak on the scope and I r...

There is a popular myth that all horn people in one way or another subscribe to. They believe that reflections from higher frequency horns off the bodies of lower frequency horns is unavoidable destructive price to pay for horns time aliment.
