Hi everybody!

I was thinking of replacing the B&W 606 S2 in my mixing studio with something else.

I love the B&W for listening to music but I found it a little too soft in the midrange for being accurate enough in the context of mixing in the studio. They are definitely Hifi, in a good way.

Now my top choice would be the ProAc SM100, since I had the chance to test the old model a few years ago and their accuracy was amazing to me.

Unfortunately they are too pricy for my budget at the moment, so I was looking for some more affordable alternative that somehow excels in the midrange as well.

Thanks for any advice...
 
Welcome to ASR. The reason you haven't received any answers yet is because you are asking an unrealistic question. I'll explain why.

If you want a loudspeaker with similar performance to that ProAc, you will need one that has the same measured performance. The problem is that measurements of the ProAc SM100 are incomplete. About the best I could find with a quick google search were some Stereophile measurements. To be honest, those measurements don't look great.

Now you need to find another speaker which comes close to those ProAc measurements whilst still costing less. There are literally thousands of speakers, most of which don't have publicly available measurements. Even the ones that have been measured, there are still thousands of them. We are not going to trawl through thousands of measurements to look for a speaker that has similar measurements to that ProAc. That is something you have to do yourself. Maybe you'll find one, but chances are you won't.

The far better approach would be to find a speaker that measures well, and is within your budget (which you did not specify!) and then go and listen to them yourself. Or, if you really want that specific sound, either save up enough money to buy them, or DIY your own.

Hi Keith, thanks for the welcome and for your honest answer.

I think my question sounds unrealistic to you, and probably to other users as you are probably right, because you are considering it from the wrong or lets say a different perspective.

The perspective in this case is not related to the intention of comparing different technical measurements of the speakers until I find the closest one, I know I can do this by myself and to be honest I would never do it at all.

My perspective was about other users experience.

In other words, a feedback from people that know that speaker's attitude.

I know that every speaker sound in its own way but at the same time I know that no speaker is perfect and each one tends to excel in certain aspects of the job of translating the sound. In this case I was focusing on the capacity of translating the midrange in an accurate and natural way, since its pretty crucial to me while mixing, unlike what happens with my beautiful B&W 606.

So, I'm not looking for a clone, but for any personal feedback into this perspective.

Maybe this forum is more related to audiophile's views and in that case maybe measuring is the first approach when evaluating speakers, if this is true I'm sorry if I asked something that is out of the context of this forum, I'm still new here.

Maybe what I'm asking its just a "feeling" about how it sounds with no objective measurements but I learned a lot by listening to other people's perception

Thanks anyway for helping and taking your time to answer me!

"Feelings" are emotional and personal, as in unique to the person involved. If there are no objective measurements to use as a baseline, then there is no correlation between two different people's emotional reactions.

I learned a lot by listening to other people's perception

Please see the sentences above.

Respect your point of view but I totally disagree.

Measurements don't tell you everything about a speaker. Its the act of listening that makes you realize how they sound.

Even if I wanted to give 100% credit to the measurements data, the psychoacoustics of our brain is so complex that you still end up evaluating listening perceptions. You listen sounds, not values.

The perceptions are directly linked to the experience, and the experience is the most crucial thing in my opinion.

Anyway I didnt want open a philosophical debate about it, just curious about some feedback from who knows both the B&W and the ProAc well enough to think of some interesting alternatives in the middle.

Tks
 
Nice pair of reconditioned Studio 100 on eBay right now for $2,500 free shipping.
Thanks!

Actually I found a pair of 25 years old ProAc Studio 100, used mainly at home for hifi listening for around 1000$ (900 € here in Europe).

Would you buy them? Any chance there's no need to fully restore them after 25 years? Unfortunately I can't test it cause the owner is very far away from where I am.
 
Would you buy them?
I own two pairs of ProAc, so I'm biased. Both pairs are beyond 20 years old and still going strong, though I don't really stress them with loud volumes. That's a good price, but it depends on condition and whether the woofers need new surrounds. It's not a particularly difficult repair, but it is beyond many peoples' comfort zone.

Welcome to ASR

A recording studio owner friend of mine likes the ProAc Studio 100 because he has used them over 20 years. He added ATC a few years ago, now the SCM45a.

ASR has a great resource in its Spinorama tests. So you can compare your current speakers, https://www.audiosciencereview.com/...kins-607-s2-anniversary-edition-review.21597/ with the ProAC using the Stereophile results mentioned in another post. Sometimes you will find reports on Spinorama.org, or Erin's Audio Corner.

If you go to the ASR Review Index, select speakers, sort by score, then you can look at the speakers in your price range, then read the reviews.

Some variables are ported/not ported, distance from the wall, and the desired vertical and horizontal listening pattern. If you have a parametric EQ in your listening chain, which is a plugin in your DAW, you can tune up your speaker. That works well with the free Room EQ Wizard and an about $100 calibrated USB measurement microphone.

Most people would say that subjective accuracy is in the frequency response, boosted highs. The ASR Spinoramas with the Klippel measuring instrument also measure distortion. The louder you monitor, the more distortion.

Depending on your location, pro audio dealers may have monitor listening rooms where you can bring your own tracks and stems and A-B monitors in the same listening room.

Cool...what do you like the most about your ProAc?

That's a very interesting link...thank you!

I like that I can be very satisfied with their sound at only 60-65 dB. On good recordings plenty of air and solid foundation. I live in an apartment and have to deal with tinnitus, so realism at a relatively low volume is an asset.

My Studio 125 are all the speaker I'll ever need and they were a bargain in the used market. Very hard to find now.
 
I’d get a pair of amphions, asking most people here about stuff to do actual work on is a bit of a fools errand.
thanks for the advice, I know they are good speakers but I've heard the Amphion two times in two different contexts: one was a full set with Sub in a Mastering Studio and the second one was in the mix room of a studio and they are definitely not for me, so analytical that they kinda bother me.

Best sounding speakers I listened to, for my taste and for my tasks, it was a pair of ATC SCM-25A..but that's another story.

Pretty curious about the ATC SCM12 Pro passive, but I heard they need a great amp...don't know how much it's true cause I never tested

I haven’t heard those little atcs either but from what I know they are pretty light on the bass, I’d maybe take a peak at genelec 8340a still would be cheaper than proac new and wouldn’t need an amp. In general with monitors I’d lean towards buy once cry once if you really vibe with the proacs.

It makes sense cause they gave me exactly the same feedback..."they sound great and balanced at low levels". This is a good thing for any contexts in my opinion. What I really loved when I listened in the studio was the focus on the midrange, such a natural and detailed sound, like piano and vocal reverbs were very clear.

I'm looking for passive speakers cause I already have main active.

About the Genelec, I know them pretty well, 1030A was my first par of active speakers more than 15 years ago and very often I work in a studio with a pair of Genelec 8341 (they are DSP corrected), so if I decided to go into Genelec I think I would go for the smaller 8331 and take advantage of the Dsp correction, cause they really translate well.
 
Measurements don't tell you everything about a speaker. Its the act of listening that makes you realize how they sound.

You might be correct about that. Some speakers have a "sound", and I regard that as a defect. I believe that adequate measurements will show these characteristics, but possibly you do not agree.

Although I admire all three, I do not admire Diana Damrau, Rachel Duckett and Sabine Devieilhe equally. I would like a recording that allows me to hear ... as close as possible ... the characteristics of each one. It is my opinion that an accurate system lets me know what is actually on those recordings ... warts and all. By the same token, I do not appreciate a speaker that adds an obvious "sound" that is not on the recording, if it can possibly be avoided. This applies especially to female voices.
These goals have been the aim of speaker (and recording) development since the 1930s. We're not perfect yet, but each year we get closer and closer.

So ... if I might ask ... how do you know what's on the recording and what's not on the recording?

Not sure 100% that I got your question correctly but I'll try to answer.

The premise is that I'm nobody, pretty new into the audiophile world, just somebody who's been recording and mixing for a long time, since this is my job so my experience is based on what I've seen with my eyes and heard with my own ears.

I've been to quite a few studios around and lucky enough to be also in a couple of Top studios. All these studios had great speakers, very accurate, from Full Range to Near-Field. Despite this, all of those speakers sound significantly different. So if we consider one of those systems accurate then...should we consider all those other speakers not accurate?

At Abbey Road they had B&W 800 series for a long time, those speakers have a characteristic sound not hard to recognise when compared to other great systems. Just a few days ago, for an Hifi Event, I had the chance to listen to a couple of Custom Made state of the art speakers, for the selling price of only 180K Euros: the sound was huge, amazing but I couldn't say it was more accurate than other speakers I heard, maybe very much detailed? Probably. Same day, on its smaller and cheaper version of the same system (like around 10K) I listened to "Walk in the wild side" by Lou Reed and for the first time I noticed some kinda room sound on the shaker, something that I never noticed before. It was very emotional. So which one was accurate?

What I see in the reality is not an ideal line that converge towards a single mythical point of listening neutrality, what I see its parallel lines where each speaker shares a certain level of accuracy and balance but each in their own way.

A senior engineer at Air Studios, said: "You don't have to listen to the speakers, you need to learn how to listen through the speakers..." When you work in a studio you don't compare the speakers in front of you to an ideal sound that you kinda own in a better speaker, you compare the speaker's sound to the sound that you have memory of, in your own studio or home.

And we end up how we started, the real accuracy is in our experience. At least in my personal honest opinion.

Sometimes it looks like listeners are looking for an accuracy that who made those records didn't have.

Apart from that....some records have been really recorded as if with the intent of wanting to take a photograph of the moment, in that specific space, room and moment, so the approach of wanting to "see" that same picture through your speakers is a beautiful approach and also gives recognition to a certain way of making records, so its something that I like and respect.

For production, I totally agree.
For REproduction, however, I don't.
If I have a speaker that is measurably accurate, I can be fairly sure that what I hear out of it is a reasonable facsimile to what is on the recording.
If, OTOH, I have a speaker that has "affected" sound (IOW, that is rather inaccurate), I don't necessarily know that what I hear is a close facsimile of what is on the recording.

My point, going back to those three sopranos, is that I want to hear in my home a close reproduction of what I heard in the concert hall. That's all. :)
