S75 classic
M100 pop
want more bass buy MS150 or another brand

Well now, that was succinct and to the point.

Like most people, I enjoy all types of music and choose my music system based on which one will play the capricious choice of the moment.

Based on your comments perhaps another brand is what I should be considering. Fortunately I have the time as it is going to take months before all my equipment is fixed.

Actually Jeff, I think you'd like the sound of the JAMO POWER series of the 1980s.
I use two pairs of the POWER 555 myself.
They are considered disco boxes but will actually play almost anything you throw
at them with quite pleasant results, plenty of bass and all the volume you'd like.
I use them for all possible kinds of music, classical, jazz, pop, disco and all the new stuff.
They've never let me down, parties included, and they seem a fine match for the B&O amplifiers.
The 555s furthermore are extremely easy to drive. 0.8W/96dB/m so with four of them connected to
my BM8000, well... I have some quite understanding neighbours.
Even small amplifiers will produce a quite impressive volume.

They are danish too.
- And they will also need refoaming to the woofers.
Make sure to get some with the original woofers, even if in need of refoaming, - they are specifically
produced for JAMO and have silly specs.

Their design can be discussed but that's a different story.

I live in an apartment builing.
If I even would play a third of what the M75 can do, the neighbours would call the police. 

The bass comming from the M75 is the dryest most detail bass sound I have ever heard, even comparing to hugly expensice top of the line Genelecs.  that cost like a new car.

Jamo Power M555, 0.8Watt 96dB

1.6watts 99dB
3.2 watts 102 dB
6.4 watts 105 dB
12.8 Watt 108 dB
25,6 Watt 111 dB
51.2 Watt 114 dB
102,3 Watt 117 dB
150 Watt BM 8000 118,5 dB, most likely 120 dB peaks

yup, you can blows your ears off with that combo, an actually cool combo 😕

Have never heard that speaker, but remember in the 80th that i was so curious, as it was a big bang for the buck at that time.

Hi Martin,

It sounds like you know me…. and of course you do.

Disco, ah yes, guilty as charged, hence the love affair with bass. But as you know I also LOVE classical, pop, show tunes, Spanish Guitar, etc.

I checked out JAMO on eBay and found nothing. Zip. So I checked out several suggested sources which all that the current offerings, all black squares.

I’ll keep researching this suggestion, and thank you.

As mentioned I am in no hurry as my Beomaster 4500 spent 5 days sitting uselessly in Atlanta and then went to Miami. (I wish I had known it was going to Miami as I gladly would have met it and gotten out of this frozen weather.)  

I don’t know but on MY map Miami is due south of Atlanta so the BM 4500 is heading in the wrong direction. No wonder the USPS is losing money with that sort of sense of direction. This was said in jest, but in reality, is no laughing matter.

The BM 4500 will replace the BM 2400 while it heads south for a suntan and repair in suburban Atlanta.

I won’t have a speaker issue until I send the BM 4400 in to be rebuilt and it returns.

Thanks for the much appreciated suggestion.

Hi Jeff As a flag flyer for M100's and an owner of S75's, I can tell you the M100's beat the S75's hands down for bass in a mid to large room.

I am someone who always likes to know they have the power 'on tap' if they need it for parties,etc. The real issue here is room size, in my small 3x3m listening room the S75's provide bucket loads of bass and lovely detail, especially in the midrange since being recapped, in my 6x5m living room, they are 'just right'. In the same size room the M100's provide an abundance of bass, you couldn't wish for more (well you could but then you'd only be hearing bass).

So where are you going to put these new beasts? If its a medium, large or small room?

If you are speaking B&O, the S75 will always put a smile on your dial in a small to medium room (which you would know), the M100's will almost blow the walls out of a small room and would be too much - they would take up half the floor space (aussie humour) but in a medium to large room they are very satisfying and you always feel like you have more on tap, plus they have overload protection unlike the S75 which use fire as overload protection (more aussie humour).

I have not experienced but have no doubt the MS150's would provide a similarly pleasing result as would the M75. Issues with the M100's are aging caps and the 4 inch phase link driver (directly atop the woofer) suffers from foam rot, its not a standard foam size so I think most repairers either trim the cone or trim a surround to fit, they are known for being a high quality driver. In one mates set of M100's the driver had been replaced by some AL brand generics which sound fine, my other mate had his M100 phase links refoamed, I cant tell heaps of difference between the two. The M100's have rubber woofer surround so no issues there. I would try for a Mark 2 version as it has some subtle changes such as an overload LED (no mechanical switches to die).

The MS150 suffer from foam rot on the sub and woofer so if they haven't been replaced, that will need looking at. I haven't listened to them but would expect their output to be even more terrifying than the M100's. Issues with the S75 are resistors burning caps due to incorrect assembly of resistors sitting on top of the poly caps and wires (my conclusion), the rubber on the phase link driver goes brittle but seems to hold out ok, woofer solder tags get loose and the tweeters can be a little more sensitive to being overdriven. Construction wise, the S75 are lovely, the M100's are built like a tank with proper fiberglass board for the crossover rather than wooden project board found in the S75. The M100's are a class act. The thing I have noticed about them when driven hard, the sound doesn't 'break up', they seem to hold their integrity across the entire sound stage from low to very high volumes, they dont get muddy at loud volume.

Lots of info :) Drew

Hi Drew,

Lot’s of info indeed…. and much appreciated!

These questions may have been rendered moot by the USPS as it is possible they have lost my Beomaster 4500. If so, I won’t need new speakers. Supposedly the BM 4500 spent 5 days in Atlanta then was trucked (why in God’s name would they do that?) to Miami. Now for those of you keeping score, Miami is in the wrong direction being due south of Atlanta. The BM 4500 has spent a full 3 days in Miami where it is sunny and 81°F. (I wish I was there!!!!)

But let’s remain positive.

You asked about the room size. Well sir we are definitely going to be moving in June, but the question remains where? If it is the currently “planned” move the speakers will be in a rather large dining room with 9’ ceilings. This room is open to the living room, which even with the tasteful columns that partition the room, makes for a big open space.

After reading your lists of issues on either the M 100’s or MS 150’s the ideal thing it to find a pair that have been properly dealt with. After the MS 120.2 speakers debacle, I don’t think I ever want to work on a speaker again! Never.

I was amazingly lucky with my four S 75’s in that the first pair arrived unannounced, one at a time, as a gift from a good friend in California who thought I’d like them. This friend bought them as singles on eBay really, really CHEAP because he just “knew” I’d like them. He was right.

The second pair was found in a dumpster along with my BeoCenter 9000 and the S 45.2 speakers.

In spite of a less than auspicious beginning for any of these speakers I have not had the slightest problem with any of the S 75’s.

That can’t be said of the S 45.2’s as each had a speaker out. Thank God for my friend in California who also sent me a pair of S 45.2’s which were white and butt ugly….. UGLY but I was able to use one of these as a donor speaker…… the other is now a stand for my 8-Track.

Thanks Drew for all the info.

Martin appears to think that I will find the M 100’s insufficient in the bass department, which is always possible. However most Europeans of my acquaintance live in confined spaces: apartments, condominiums, or townhouses and as such a lot of booming bass would be unwelcome at best.

Oddly enough the place we are planning to move is a townhouse and I am beyond concerned that there will be a sound issue.  

Back to Martin, I am not certain but I kinda think that I may have overstated my desire for bass a few too many times to Martin, hence his concern. On the other hand I confess that I really did enjoy Saint-Saëns Organ Symphony at a volume that vibrated a souvenir ash tray from the Queen Mary off the ML-2 speaker.

Anyway, thanks again Drew for the information. We’ll take this one step at a time. First I gotta get my BM 4500 back, the rest will fall into place in good time.

Hi Jeff,

I am currently listening to my MC120-2 and they sound gorgeous. Voices are superb and oh that cristalline treble. Go for those. 😎

More seriously, the bass level will depend on your cubic space. Small speakers like the S45 will produce extended bass in small rooms, too much against a wall. I listen to my speakers well away from the back wall when I can. 

Even in my 35 square metre lounge they thunder when placed against the wall, not too good actually. Don't buy if you cannot try anyway.

I have the opportunity to purchase four S70 speakers with their tulip stands... I'm thinking.

M100s have plenty of bass - it doesn't boom because it is accurate - the MS150s are much the same - lots of detail. The ultimate expression of this is the Beolab 5 which has wonderful detail without booming whilst you are in the room. Be a neighbour though and you may disagree. All of these speakers encourage you to play music loud as it doesn't sound boomy.
