So,..now i must go sleep...
Stay tunned..best wishes...

the parameters of these speakers can be very overstated, mainly for electric power,
eg subwoofer with a power of 100 Watt has a coil of wire with a diameter of about 0, 3 mm tweeter with a power of 180 Watt [that gives a company producing Speakers] has a coil of wire about diameter 0, 07 mm, which is the power given by manufacturers It depends on how it is actually true physical. I read somewhere about speakers that their real electrical efficiency does not exceed a few percent, whereas for example the induction motor has an electrical efficiency of approximately 70%, toroidal transformer has an electrical efficiency of over 99, 9%. What exactly is the truth about the speakers? Has anyone thought about this?

[dimi751]

No I have not thought about this

Hi sakuszi,
The points you make about loudspeaker efficiency are really quite interesting, they're about as efficient as a Steam Engine so not the best in terms of converting inputs to outputs eh?
A quick Sneaky Beaky on Wiki for a brief synopsis on Loudspeakers reveals
Typical home loudspeakers have sensitivities of about 85 to 95 dB for 1 W @ 1 m—an efficiency of 0.5–4%.
Sound reinforcement and public address loudspeakers have sensitivities of perhaps 95 to 102 dB for 1 W @ 1 m—an efficiency of 4–10%.
Rock concert, stadium PA, marine hailing, etc. speakers generally have higher sensitivities of 103 to 110 dB for 1 W @ 1 m—an efficiency of 10–20%.
Much more information can be found if you look at Loudspeakers on Wiki, and depending how deeply you wish to explore and delve into this, there exists a massive body of literature by the A.E.S and others in which more answers can be found. Though I must say Wiki is quite a user friendly explicator of some of the more abstruse elements pertaining to a great diversity of topics, and will usually guide you to more in-depth articles for further analysis.

thanks teddy bear, that's what I was looking for and now it is at a glance! The conclusion is that the speakers are the worst commercial and consume electricity producing heat and should produce mechanical energy, if my reasoning is correct? Then how to increase the efficiency of such transducers?

Hello everybody,

my vinylrecorder is working very good and i'm very happy with it!

A few hours ago, i cut a record from a good friend of mine and now it's on youtube.

I filmed my recordplayer, and record the sound to my pc.

Then i put everything together, so you hear the result of the vinylrecorder with it's new tweeter!

Cheers Marc

yeahh .. marc, which I am very pleased. I also made a few test and I must say they are really good drivers. a few distortions are still there, but hardly noticeable. wants to again read out the frequency response. will get back to you when I did it.
The main thing is only once that your VR is running again!

Gruss Scotty

This driver tweeter is great for t560 repair...

Hi Marc


I want to buy these thanks to you and Scotty

https://www.red-carparts.de/car-hifi-auto-lautsprecher/hochtoener/phonocar-hochtoener-tweeter-pro-tech-200w-2-419

Is there any way you could post a picture of the tweeter back section where the magnet is ?

I just want to know if there is a screw hole inside the magnet this makes it easier to mount onto aluminium

I've decided to try making a cutter head from aluminium instead of abs 3D printed.

Cheers

Dimi,..
showing in my PDF EMPHASER there are the Tweeters ( Titanium ) whith Center-Swrew,..(original!)
otherwise u must make a little Centerwhole in the Magnets but better is, when u glued a fem-Srew on the magnet in backside with loctide

hey Saku,..

don´t take a 2$ Speaker for VR.
buy a tweeter whith 100 / 200w Titan Tweeter (look at DIMI´s )
or take an EMPASER Titan Tweeter ( look at my PDF )

I ordered these speakers from Germany, fly a plane across the ocean, the sea at the end of the week I'll have, and will head vinyl recorder 3, thanks very much for the support you Mr Snug Music
I have problems with the network, hum through the line, there was no grounding and a terrible noise, please listen to this [if it can be compared at all to hear ....]

hey Saku...

Humming noise made by the network. (Grounding). Did you listen to other problems?
Noise? Where does the noise? Have you checked your settings? Counterwight ect.? What is your loading weight? Have you considered your Stylus ever under the Microskop? Take a photo! Can you make times a photo of the grooves?

Ich mag die Deutschen! Vielen Dank für Ihre Unterstützung, ich freue mich auf die nächste!
Der Film ist in Ihrer Sprache! Super!
Ich griff nach 12kHz! Motorgeräusch sehr groß, aber es war die japanische Geräte [hart für mich, es zuzugeben, ....] Motor kleines Bier!
Es gibt 12 kHz, und es ist üblich Leistung. Nochmals vielen Dank! Saku
Ich lade Sie hier wieder, ohne Ende

hey Saku...

Yes, so the hum came from the engine!
the distortions come perhaps from your settings or the drivers!

PS: yes .. and I like Japan ... This year, I want as well take a vacation!
and yes! I'm a fan trekkie (star trek!) comes also my nickname Scotty ... (because I always come up with something in no way out seeds!) hehee .... smile
