I will start with 3800 later. Now time for trumpets.

These stands are not the same like from M70. M70 trumpets are heavy and made from thick naked aluminium. All scratches I can polish. In 3800 aluminium is thin and light, easy to dent. Aluminum is covered with colorless varnish easy to scratch. When scratches are deep you can't polish it without varnish damage.

My stands are full of deep scratches and punch.

I removed all punches from botom side and removed all scratches and varnish with sand paper. 

Tomorrow I will sand blasting all surfaces with glass microgranules and after that I decide: polish or colorless paint .

Trumpet stands episode 3

When my friend called that, the stands are ready, I was in my car in 2 seconds. I couldn't wait until tomorrow. So I'm in the paint shop and my jaw dropped. 

My jaw dropped second time today, first time when I listening 3800.

When I listened through the SS amp, the transistors gave Beovox 5702 wonderful sound but my tube amp made the vocals backwards and hid somewhere on the stage ...

because I have 3800 bought for trampets and I renovated it: https://archivedforum2.beoworld.org/forums/t/42671.aspx

I conected to amp and at the sight of Beovox 3800 vocals ran back onto the stage and sang with great power and energy. The sound of the guitar that accompanies Mark Knopfler voice at brothers in Arms again got that claw that falls under the skin.

I like 5702, do you think that problems can be in 5702 xovers ?? If you remember 5700 were 2 types of crossovers. My is this older ( maybe the only ones that were in 5702 ) with impedance pick - red one.

tube amp is very sensitive on impedance changing and maybe when I change crossovers to 6253 type, my 5702 will sound better ??

This year Santa came earlier Big Smile

 

Now I have twins :

and one extra M100. 

 

All last day and half night I listened and compared sounds from these beautiful speakers. 

 

and from the first sounds in my head I had one question: Who the hell called the M100 the best of Beovox !!!

You listen to M100, then 5702 ... and you think someone finally pulled the blanket off the speakers and it started to sound. Here are some differences:

- Hi tones have more details on 5702 and larger range

- Mid tones in 5702 sound great in M100... this is perhaps the biggest failure

- Low tones, yes M100 have stronger bass but this bass kill rest of sounds, in 5702 bass is enought strong and with harmony with rest range.

- Scene, in M100 you have right speaker and left speaker, when listen 5702 you have 3D scene and speakers disappear as a sound source.

After my first listening, my friend, who has always wanted the M100, also came to listen to these speakers. When finished called the M100 a "great disappointment" ( maybe he wasn't objective because he has 5700 ) but... today one owner of the M100 also decided to listen to 5702 for the first time and said exactly what was written above and that "he lived in great ignorance thinking about the greatness of the M100" 

Between 5700 and 5702 the differences are insignificant, both models have different crossovers, I think in favor of 5702 ( very little stronger bass). 

I also know the 3800 sound which is close to 570x. Maybe the speakers have less power, but the sound quality, fullness and harmony also beat the M100 at 100%.

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

 

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) and digital files through Musical Fidelity DAC.

 

but the same result of the comparison were on the NAD, Beomaster 6500 and Ayon Spark tube amplifiers.

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.

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?

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.

Daily I use old classic Infinity speakers with my fully Class A amplifier. Impedance on Infinity is like a short circuit Smile ... and Infinity also plays better than M100. My amplifier is enough strong to play with hard to play speakers. I checked M100 with Gryphon Antileon and result was the same pure. All caps are new, foam susspenisions are new. It is not the best BeO speaker. Yes, bass is big and heavy but for me to dominant, high and middle.. I heard better. It's not only my opinion. 

The M100 is designed to works with the Beomaster 4400 (I have one), It's maybe strong, but not powerfull amp. Has problem with drive my Infinity. Maybe few years ago it was good for me... but now I appreciate the singing treble and the beautiful midrange above the bass impact. The bass is an accent, it cannot be leading. It's the reason that 5702 is better then M100. 

Now M100 plays in my friend home after fully restored by me.

Du mener sikkert, at du seriel-koblede dem.
- Ellers bliver de jo ikke bipolare, og så går det altså galt.

Isn't it great, that you can pick and choose between amplifiers and speakers?
You can set up exactly what you want (money, room and time allowing) and tailor it to your preferences.

Beovox 5702 are from a time, where speakers were often the weakest link, so being B&Os top range model at the time they were made to REALLY get things going,
- and they are excellent speakers in their own right.
They have the pleasant and, in their own way convincing, sound, leaving an impression of having lots to give, not sounding as if they are being pushed - even if actually being pushed.
It's as if they just ask you to "bring it on", - don't they?
I like them a lot. Just as I also like the 4703 and even Beovox 1702 and 2702 for what they are and was meant to be.

Now "rewind forward" to 1978 and think back.
When I do so, I remember sitting in the front row at Bang & Olufsens demonstration in the local Odd Fellow mansion, next to my father.

We were both into music, not audiophools to any degree - no, we both had enough technical background and knowledge to know
what was right and wrong, but rather we were into music and what sounded good.

The brand new Beovox M100 speaker model was demonstrated, using a Beomaster 4400 and a tangential Beogram.
This fairly large room with apprx 25 listeners was filled with sound.
They played classic music, swing, piano and violin and modern pop music. I particularly remember hearing
Boney Ms Nightflight to Venus album for the first time on a "decent" (fantastic and out of this world) setup.
We were blown away.
We'd never heard anything like this before. So detailed, and yet so powerful.

A Beosystem like this was completely out of reach for us, but a year or two later my father bought a Beomaster 4000 and a pair of Beovox S60.
It worked quite well in our 20m2 livingroom.

I had already started collecting B&O a few years earlier, but of course it would be several years before I could include
my first pair of Beovox M100 in my collection.
At that time I had already bought other speakers that I was using on a daily basis, but I still remember "recreating" the
setup I experienced years before.
Hooking up what was now my own Beomaster 4400, Beogram 4002 and Beovox M100, loading the Boney M album and pushing the volume up a notch.
And there it was again...

Yes, there are better speakers (now).
Yes, there are better amplifiers (now).
Yes, there are better album recordings (now).
- But is that the point?

Hi Martin.

I really respect your voice in the discussion, always substantive and always fully knowledgeable.

I wrote about other amplifiers and loudspeakers only because it was mentioned earlier that it might be the fault of the amplifier. Of course you can find better speakers, better amplifiers, there is always something better but I tried talk about BeO.

The second thing is that we are talking about music and music reception. It is probably the most subjective sense and the perception of sounds is very individual. We are tuned in different ways.

Yes, M100 are great and powerful but in BeO enthusiast world (  not only a beoworld  ) M100 are like something saint. I tried to feel it but... 5702 are better for me and I don't understand excitement of M100. 

If I play M100 I hear music, if I play 5702 I hear and feel gooseflesh. Do you know this feeling ?? For me it's mean only one. It determines if something is better for me. Only one of the mentioned speakers gives it to me.

BeO is like a good wine - the older the better...

Here are videos, I know it is only reproduce, not source directly to your ears. If you play it on stereo or headphones you should heard differences. 

M100:

5700:

Maybe it's something wrong with my ears but for me, my family and my friends 5700/5702 sound better.

Yes, I know the goosebump feeling.
But I don't get it from B&O speakers.
With my Beomaster 8000 I use speakers from another danish brand.
That's my favourite combination.

I see that you are not alone here on forum. 

 

I feel it from Beovox when I hear 5702 after M100. For me it's a sign that something is much better. Goosebump feeling daily gives me my another set.

I started love music with first BeO, now from BeO in my home set I have only Beogram 1800 (5213) with RIAA card from you.

P.S. I use only Beogram turntable but I have still something new from BeO to restore:
