Yes Janos it is a pleasure to share good things....
And Lou must have much pleasure listening with the Supravox field coils.
And those are realy reliable too....
Indeed the batteries my brither uses are huge and very powerfull ..........there's a little secret about bayyery powerd electronics........indeed there might be no RIPPLE ....................BUT there's some noise generated by the chemical reaction............it is very small but can be revealed by very revealing systems and especially one does not hear it but become aware off it's presence when it is ELIMINATED !!!!!!!!!!!!!!!!
Just like you miss something after it's gone.........
How to suppress this tiny noise ???
Simply by a very small coil or a BYBEE ( the heavy ones...and if necessary two ,in parralllel but then turn and tune a coil and look on a good scope for noise on the DC ....)
Asthonishing the difference between ........magnets !! ............Ceramic ................Alnico ( has a different construction , magnet in the middle !! ) ,.......and the Field coil drivers..............
As I mentionned Tangband is also interesting.................I am not such great fan of the British Lowther speakers ( Craft paper, cone shaped instead of exponential )
There are many and even cheap speakers to begin with and discover this is quiite different way to approach audi prroduction...first what it can not do as some high end speakers but then to discover what regular speakers and of all price tags CAN NOT DO !!!!!!!!!!!
Have a nice day everyone .........
FReven modest can get you to stay awake ALL night .............even at low listening levels being captured by the magic of what should be music .....
quite different to be highly impressed by high end audio ... and sometimes want to shut it down after only 25 minutes .....................
Hello Janos and everyone...........the body , all matter is subject to the second law off thermodynamics .............buit the soul is the counterpart of matery............consiuosness and information ( creation ) is the engine ................Money tries to educate our children otherwise....
And yes a smile is more important for oneself and the other.
Music is what make life a so,ng to live and share............
Greed and competion are a trap where humanity stumbles into ...........sharing and creating together is the real goal of live........and music is the smile ...............that is the link where words are not understood.
I am very happy to share with all of you...........nobody has all the knowledge but any sharing little bit of experience is as valuable becaiuse that's the essence...........the biggest problem on this earth is unite the human souls.........because all power would loose the power over your life...
Audio is a tool ................a tool that can unite us all and real world audio is part of it.
Thank you Janos and everyone who shares the passion of music and sends a smile ...............
For those interested in quality speakers.................There is this old French manufacturer ( they equiped for years the ORTF in France )....
Splendid quality !!!!!!!!!!!!!...............SUPRAVOX.......https://www.supravox.fr/
Video demonstration follows ......
https://www.youtube.com/watch?v=eFty1A73Ck0
They have Alnico FR drivers and also FIELD COIL drivers for the very passionate under us ........
As shown in the video above, this is a demo with a field coil Full range driver ............just listen even it's on YT ...........image in real audition......
Filed coil FR drivers gives you the possibilty to adapt/change the parameters of the Loudspeaker ....( variable voltage on the coil ) ................needs a lot off attention to the quality of the current but its rewards the effort .............
Batteries are NOT cheap ( marine quality )
The James WEBB telescope brings us Closer to the wonders of the universe.....not to make the stars , planets and constellations brighter ..........this is what technology in audio should provide us...............bring us closer to t he soul of the music.........bringing us closer together ..because music as created by humans is a language of connecting our souls and not pure amplified sound...........and there's the music of nature , music of a universe we are part of........often we forget that in a ....................growing up and teached to a belief system of a material world...only.....
Every technology has it's benefits or /and shortcomings................BR is a commercial solution to produce bass levels unexpected relative to the volume of the speaker....in ( to ) many conform to the " wife acceptance factor " and to keep the peace in the household ( am I sexist ? )..as well as for financial considerations ( cheaper than bigger enclosed speakers )..............great bass from a relative smaller speaker rather than the bass of BIG high efficiency speakers /Volume monsters in " comparison " ...........everything being relative ( thanks Albert ! )........... IS it the same bass experience and expression ...........NO ! There's a BIG difference between heavy bass , controlled loud bass with impact and the very fast bass without the bumps and the rainbow of all ,the colors of the bass notes , just as RICH as in the medium ..............mostly absent in most commercial speakers.....the same dance and feelings of nuances that makes music sing in all registers.. real deep bass is not in the amount off bass delivered but in the feeling of the presence and experience of the SOUNDSTAGE.................the place where it happens .........the space be it outside or in a church , a room , a castle ............or whatever ........and the feeling of the air present when the recordings is taken..........one can sometimes feel the weather , cold or hot , rainy cloudy day , morning sun or evening atmosphere............that's what a very revealing system is capable to set a scene ..............and that's the paradise of tubes and high sensitivity speakers ...and good sources ( mostly analog ) ...........When it works .............one instantly recognizes the natural world with it's magic without the gimmicks glorified by a certain kind of high end illusions.... Well içf that suits the demand and expectations............than glorify and standardize the BR as the standard ...........Whatever ! Do I have BR speakers .....................YES I do ! ...but not only BR speakers !!! What is a good indicator for a CORRECT tuned BR enclosure and speakers is inside ......... have a look at the impedance curve.................there are TWO distinct peaks in the low part of the impedance curve...............IF ..........they are similar in value and dimensions..........then the BR was well conceived ..............Many are not ! Pushed in output volume there's a tendency to start hearing the PUfffffsssssssssssssss. Many try to limit those BR defaults...... Below the cut off frequency the BR shuts down very steeply....................Closed enclosures fall off more early but the slope goes down gradually ................so it can be compensated with a boost in the lows.........( within limits of the amplifier and the speaker output ) Bigger or huge close enclosures have the advantage in the lower registers ...........and what I like about it is the "speed" of the bass instead of the resonanced bass off the BR. But anyway as long as one can enjoy any technology ............... I am curious about the Voight pipe for several decades , Maybe it's time to think about realizing one ......... Nothing compares ...........as in that song............... A sunny day to everyone. I have a pair of P3ES ...(BR) ................and a pair off old KEF 101rr.............( Closed ) ................I listen more to one of them than the other ( proximity listening ) I position them like listening to free headphones ......or better ear speakers....and that works well in that case............with bigger speakers it doesn't, with near-field style LS3/5 it does . Does it compare to tube SET and high efficiency speakers.............NO ! But can it be enjoyable and musical with a good source and a good amplifier at a moderate listening level ?....................YES. SO everything is RELATIVE................When music flows into your heart ......ALL is OK whatever make a good combination that one can forget when listening.........
