Great video, good job.

*How many Ohms does this exact one have??* Thanks in advance

iPad Speaker test

Really is speaker used in the place of mic😮

У всех разбаланс в ту или иную сторону. Дайте нормально умереть этому архаизму

If the Spviet Union did what China is doing today, we may have had some serious contenders in the hi-fi market. Would have been interesting.

Surprisingly solid looking deck. Respect the direct drive. Is it a quartz lock system? Or just basic direct drive? Not seeing any Dolby buttons on there, lol. Does it use an alternate noise reduction system, like Dynamic Noise reduction or something similar?

Whole this isn't exactly what one would call top hi-fi, and never mind using a surround from another speaker, was it really that to find another new surround for it? Even something which fit the cone diameter, but has to be trimmed down tonfit the basket? Now personally, I like the what looks like a die cast basket, I'd just try to replace the cone and voice coil with something better. Otherwise, still a clever repair.

Interesting gear. Any chance of an in depth rundown of the controls and connectivity of the amplifier unit? Looks fun to experiment with.

Small speaker from iPad the sound is quite smoother deep bass and perfectly slam of sound with warm sound but no muddies of bass but good for DIY small speaker box to amplify the sound when connected from cheap amplifier with Bluetooth,USB,FM Radio and AUX input for wired devices and its impressive sounding with original audio output from iPad.

Dude did you upgrade this motherboard ?

Nicely done. I love that vintage look with the hand made PCB and the soviet transistors from the sixties. That's almost combining electronics and art.

👍👍

None of them sounds as good as a CD.

MP-120 beszerezve !!!!! Kimondottan szép !!!!!!!!!!!!!!! 😊😊😊😊

Hello, I have a question about the added spatial sound effect button. I saw that you have facelift version of the buttons line. I have e46 1999 and I have the whole button but dont know where all the wires go. Can you help me with that please? Thank you so much. Kaufi

GZM best to best!

Does anyone know the diameters of the foam?

so, at the end: which one is the best ?

Подскажите пожалуйста что это за колонки euromatic s150? Похожи на s90, но у них всего два динамика.

Great video👍👍👍. Couldn't find any appreciable difference excepting that the Russian one appeared to be a more detailed with some airy treble. Would like to see a video as to how you connected the resistance and capacitance with the BUM cartridge.

I took 2 Chinese models, it seems that the heads are all the same, just change the cover, BUM 1M AND STYLUS (ortofom copy) needs 12 hours of operation to start working, Stylus the more weight the more bass it produced with 3.2g, BUM 1 catilever was too deep Leaning against the magnet wall, I removed the rubber and adjusted it. the sound was pleasant

Mine doesn't have a serial number, though that could be a fake one but no it's original made in Australia. We're can I find the number that on mine is not in the back?

Hello, thank you for the video, the link doesn't work and I can't find the sizes to buy new ones

In my case the BUM M1 has better treble quality, and very good bass, even good sub bass. But...for some strange reason the BUM M1 captures the magnetic field of the power transformer of the Marantz SintoAmplifier, I changed the head for another one with an AT-95e set and then for another AT-3600 and the hum disappears. I reinstall the head with BUM M1 and move the tray from the rack mount to another base, about 50 CM (20 Inches) away and then the hum disappears. Has anyone had a similar experience?

En mi caso la BUM M1 tiene mejor calidad de agudos, y muy buenos bajos, incluso buenos sub bajos. Pero...por algun raro motivo la BUM M1 capta el campo magnetico del transformador de poder del Sinto Amplificador Marantz, cambio el cabezal por otro con un conjunto AT-95e y luego por otro AT-3600 y el zumbido desaparece. Vuelvo a instalar el cabezal con BUM M1 y muevo la bandeja desde el montaje en rack hacia otra base, a unos 50 CM (20 Inches) y entonces el zumbido desaparece. Alguien tuvo una experiencia similar?

thank you, your video is really informative. i like how you have more technical data and comparisons, but also your own anecdote. i was worried that the difference would be staggering, but after hearing your thoughts im at ease

Mostly indistinguishable to me. Why waste time on adding resistors to a faulty POS stylus/cartridge? Just throw it in the trash. AT 95e and AT-3600 win because of consistent construction.

como se pude conectar a un auto esterio?

Послушал сравнение на колонках с неравномерностью +/-2,5дб. Что тут сказать, надо радоваться той игле, что уже имеешь, а менять "шило на мыло" я бы не стал, разница не "вырви глаз" какая. Главное, что не вытекшая ГЗКУ))) У старых ГЗМ-ок часто пересыхает единственная резиночка-иглодержатель, от чего АЧХ начинает плыть, но им и лет-то сколько! Заточка ГЗМ-ок другая, это известно, зато такая заточка менее требовательная к тонарму, а он в СССР бывал укороченный (2ЭПУ65СМ).

What’s the song at the beginning

Excellent video, one of the best I've seen on KZbin. I'll be going into my HK 7.1 speakers in the near future so I ordered up a frequency generating cable for my phone and the proper glues for doing the job. I loved the sound when I got the car but it has degraded over time. New speakers are unobtanium so repair is the way to go, and, to be honest, it's probably preferred. In my research I found that if you made a 3.5mm adapter cable for your phone, and put out a 50Hz continuous tone, you can adjust the spider when you are gluing it so that the voice coil does not rub. This seems to be preferred over shimming and looks easier. There's a video on that here => kzbin.info/www/bejne/hKGwio2nYtaEhNE I haven't done the job yet but your video will help a great deal. Thank you for making it !!

В правом канале по низам перегруз проскакивает

Very nice job, but sorry the harman kardon has a very poor sound

Cool video! - did you have to change the head unit with some "special" business CD which has additional pins for Harman/Kardon, or any BMW business CD will do the job?

did you use acetone for de-gluing? it de-glues surprisingly quickly

Wow! I like how thin it is!

Good job!

Странно что этот динамик выпустил завод "Динамик"Гагарин. Их же выпускал Рязанский радиозавод. А как ход вообще? И центр шайба сильно жёсткая ли. Думал такие динамики заказать.

Amazing restoration!

Nice speaker and nice work. It sounds great!

Very nice repair. Nice looking speaker too. I'm also glad to your still doing audio therapy sessions 😄

Soviet speakers looks weird but they sound so good

Very nice work bro as always!

Nice job. 🎉

You plan on making any more comparison videos like this?

Hello, does this system have a slight right side bias when sitting in the driver's seat and the spacial surround is active?

just close your eyes and listen, and check later which cart opens up the soundstage..its the GZM.
