This year Santa came earlier:

Now I have 570x twins and additionally M100.

I spent 2 days and one night listening to these speakers to compare them

and let me tell you one thing ... who the hell called the M100 the best of Beovox !!!

Here are some differences:

- High tones, 5702 sounds clearer, higher, more detailed

- Midrange, the 5702 is beautiful on the M100 ... that's probably the biggest problem

- Low tones, yes, the M100 sounds more powerful, but this bass kills all other sounds, in 5702 it is sufficient and creates harmony

- Stage, the M100 has a left speaker, a right speaker, 5702 is 3D, the speakers disappear and we are surrounded by sound

- Higher efficiency 5702, play louder at the same volume level

It is my opinion but after this a friend of mine who had always wanted the M100 to listen to these speakers came and put it in one sentence "M100 is one big disappointment" and noticed everything I wrote above. The third person to compare these speakers is the owner of the M100. After listening, he stated that "he lived in a bad awareness that the M100 is the best Beovox", "I turned on the M100 and then the 5700 and it sounds like someone took the blanket off the speakers which muffled the sounds" 

I also got to know the Beovox 3800 sound. Yes, they are weaker in power, but the quality, coherence, harmony and range of sounds also beat the M100.

So how is it with the M100 ?? A urban legend ??

And it's not that I'm trying to prove I have the best speakers. Currently I listen to music through Infinity, which I will not talk about in this thread. I just transferred my and 2 other people's impressions to this post. I also have recordings comparing both speakers on youtube.

At the end, about the sound source because it can be important.

A 2 x 50W class A tube amplifier personally transformed by Lukas Fikus (Lampizator). Beogram 1800 (5213) turntable with RIAA preamplifier from Martin (@Dillen), digital files through Musical Fidelity DAC.

but the same result of the comparison were on the NAD, Beomaster 6500 and Ayon Spark amplifier

Hi there,

I haven't heard the 5700, but compared many of the Beovox. I still have M100s and M75s alongside S45s. The M series are not very efficient. That is true and makes comparisons hard at times. You always need to crank up volume a bit to end up at the same level of volume as with the speakers you are comparing them to. I did my comparisons with a Quad where you can easily switch between speakers. The M series are balanced speakers without any weakness if you ask me. All other speakers I have listened to were less balanced. I find the midrange on M75s and M100s not lacking at all, by the way. From my point of view that is their particular strong point if anything to be highlighted. However, the S75 and S45 are also great speakers in their own right and not to far away.

Greetings,

Kai

Of course, I equaled and changed the volume level, I made comparisons at different levels, adjusting them to the connected speakers.

All these differences to the disadvantage of the M100 and the advantages of the 570x were heard by everyone who listened to them, from the very first sound.

And yes... the M100 has a middle tones but compared to the M70. Compared to the 570x, middle are hidden. This is not "this" forum, but if I am to talk about balance without losing sound, I would point to my Infinity. They play full tones like 570x and they are neutral. I cannot name a winner between my current 5702 and my RS, although the RS certainly have stronger bass.

Hi Martynka - really enjoy this thread and I love that you have compared the speakers that I have owned with the ones I now own (5702 and M100). Also that you are using Tube amplifiers - I have tried tubes with my M100's and only one was powerful enough but it gave out too much bass. I was dissapointed with the M100's as they semed to lack oomph, but i discovered that this is because they are difficult to drive. Recently i bought a refurbished Quad 303 and this made them sing compared to anything else I tried so I am keeping that for the moment as a system.

You've done an amazing job on the speakers - I wish I lived closer as would love to compare the speakers in person - maybe you could do a YouTube video? - now I am off to search ebay for some 5702s again!

Hi, 

My tube amp is enought strong because can drive my Infinity RS speakers ( it is not easy to do ) and 300 watt's  Marantz LD300 , now I have also one of the best Marantz amp, model 2270 but M100 still sound pure compare to Beovox 5702, Infinity RS 6000 and Marantz LD300.

I have video and later I will put it on YT and here.

Hi - that would be great - look forward to seeing it.

By the way - have you recapped your M100's?

Does anyone know the difference between the 5700 and the 4703, which I own?

great thread.  really love these kinds of posts.  

Hej.

M100 er specielle, de kræver en virkelig god forstærker, og som er strømstærk, og så har jeg erfaret at M100 er udviklet en del gange i delefilteret, M100-2 sker der er en del som lyde meget bedre end M100, men selv M100- 2 får lavet opdateret hen ad vejen. Jeg kører med Aragon 4004 fortærker, og det rykker, den kan køre ned til 1 ohm, det noget M100 kan lide og give dem en særklasse lyd. Så har jeg skiftet modstandene ud til sti lyd, det gav dem mere ... og når det er sket kan Beovox 5702 godtt pakke sammen, men 5702 kan køre af en billigere forstærker og lyde godt, det kan M100 og 100-2 absolut ikke. Her er en dansk test du kan læse.

Og husk at skift alle kondensator i M100, de alle færdige, som meget færdig..jeg gjorde det det jeg parallel koblet Selmic 2 kondensator så de blev bipolar, og det gav rigtig meget!
