Why are hi-end active monitors not more popular?

AGGHHHHHHH!!!

Anyhow this is why:
1) You need a wall outlet for each speaker - any active speaker.
2) As someone mentioned I think, most are voiced to be listened to in the direct field as near or close-field monitors. I do not know how much the designers takes into account reverberant field which makes up 50% or more of the sound you hear.
3) Most are voiced for studio monitoring not home listening. That means they are voiced harsh or bright to hear into the mix. Maybe some people like this voicing, but I don't and I don' think it is a natural sound.
A perfect example is Tannoy. The rep told me their active monitors are voiced with an elevated "presence region" ( I think that is what it is called) in the 3khz region. This is so you can hear into the mix. Tannoy voices the identical home speaker to be flat or recessed in this region. Different voicing for different intended use.
4) I did not say ATC's were poorly implemented. I said

"Good concept / bad implementation is the usual problem."
the most common problem is how they are implemented, not the basic concept.

5) Cheap amps that are bright and lack harmonics, delicacy, or natural sound as this is unnecessary for studio monitoring. A perfect, and surprising, example were ATC active 20's. The dealer also had the identical passive version. He *did not* want me to hear the passive run with ATC's 300 wpc integrated. He did agree but used lamp cord and whatever to make them worse. But the passives beat the actives because of the better amp. The ATC dealer in Canada verified the same thing. Customers preferred the passive version.

I think active speakers are great and the ATC 100's one of the best speakers I have heard. I even asked the big wheels at Stereophile show in NYC years ago. They thought active was good only for home theater since you don't have to make shelf space for 5+ amps.
This is another reason why I like single driver. One driver / one amp = "active speaker". Especially with no x-over or baffle step correction.

I have also heard KRK, Genelec, Dynaudio, Mackie, Truth, Tannoy, and maybe more. The Genelec was the best as far as neutral. the Dynaudio BM5 where spectacular, especially for the price - they blow away the comparable passive and are cheaper all things considered but dark. KRK V6 were nice for the price but I do not like woven cones like kevlar.
One thing they all had in common was amazing bass depth (for the size) punch and impact that hardly any passive monitor can match.

Here is another good article written by none other than Billy Woodman of ATC on the virtues of active speakers:

Ok,this is gonna be a long post ,so i split it in two parts. Part one: Fundamentals:Most people forget,that the only one ,who has clear perception of what real instruments or performers sound alike ,are the Talented musicians/performers + mixing/mastering eingeneers.The professional field has the advantage of comparing ,what is the real instrument/performer sound alike ,right in the next room? Or on the stage...Most of the recordings we hear,are done via expensive equipment(and some Grammy Award recordings have been mixed via generic equipment or headphones).The professionals are not easy to fool.They are looking to price/performance ratio and how the recording translate via the monitors they use.Using active monitors,at some point you will reach the point of diminishing return.For me,that comes at +$3000 (see my second part for comments).Some brands release monitors,that have a lot more to do with their :house sound: that they are ready to admit.Dynaudio,Focal,Adam,Jbl come to mind...
They dont use the latest audiophile valve/digital amps,but what they give you, is a:look inside:in the mix/recording.Some people like that,some dont.I,ve seen reports,that active monitors are designed for near field.With over 105 db spl ,i dont see how is that a problem.Move your listening position back,or raise the volume knob(is there for you to use it).Active monitors are used for mixing purpose(in general)on or near mixing console.Mastering usualy is done via fullrange speakers(and some use monitors+sub for that purpose).Do not confuse your room (my included) with professional studios.They employ a lot of bass traping or acoustical treatment in general.Products like Tact,Deqx, are being employed in active monitors like Focal,Genelec,Jbl(different RMC at a price).I,ve always kept my ears and eyes open toward professional field.Many products have come from them.Analog stages,AD/DA converters,monitor controlers,they all come from people,who use them every day.Personal evaluation is very important(for speakers/monitors).The closest Guitar center has some monitors for you to evaluate(not perfect conditions,but is a start).If you prefer :euphonic:sound (as are most of passive monitors/speakers voiced:) you will be better off with passive monitors/towers(at a price).Active monitors are not fullrange capable, but they can work (provided your room permits) with subwoofers.I mentioned certain price/point and after that,you may prefer passive/monitors/speakers.Digital domain.com. Here is Bob Katz(mastering )using Lipinski 707 with Velodyne DD subwoofers(Pass Lab amps on the monitors).Even if you are not critical/audiophile listener,you may become one(using active monitors) if that is your thing. Cons: Yes, they are black boxes,but there are exeptions..Power cords/interconnects- not a problem,unless you are audiophile willing to spend $1000 on them. Part 2:For the last 5 months i,ve been lucky to audition some active monitors in my room 15/24/12.Arcam C-30 sterteo preamp/laptop/Dac-1(loan) Rme Adi-2(loan)/Hag USB.Monitors : Event ASP-8/Dynaudio BM-6 mk2/Yamaha dsp-7.Events are very engaging monitors.Good midrange,strong bass response,wiil work with classical recordings(extension bellow 40 hz),Dynaudios are worthed well above their price range(all speakers are $1000-$1200).Dynudio: loses lower extension to the Events,but has clear midrange and top(compare to Dynaudios at $2000+).Yamaha:strong midrange And top(even via Arcam).I,ve also auditioned Adam-7,in different set up(studio),very good ribbon extension(top),upper midrange very good,lows not prominent.In my room, monitors where at 12 feet+ from my listening position.Best position was at roughly 15 feet,there goes the nearfield design for active monitors...I mentioned my price/performance ratio in the first part... $3ooo.That is the price of what i consider good professional monitors.I was looking to audition the Focal Solo6 monitors, but by pure sheer of luck i,ve heard the Focal Twin6(home set up/Arcam Av-8) and thats why the price/performance figure.They come at $2800 with 2 /150w + 1/100w amps + BE top. Perfect...? No... but i,ve not heard better at that price and no I,m not audiophile.Due to my room set up I think that Focal Solo6 might be even better(2 way at $1800) but I,m going for the Twins. In the end,lets not forget, that all the equipment we use is just that-a tool to REPRODUCE music. I,m sold on the price/performance ratio found in the quality studio monitors... YMMV.It is awlays funny to me to see systems in the :all as sault:thread,housing thousands of dollars of equipment in room without any clear conception of what the limits of your rooms are.Adress your room acoustics first,music will come later.On a different note,if you dont like MUSIC itself(THE LANGUAGE OF THE GODS), no amount of :audiophile: equipment will make it better. Sorry for the long rant, its been a long day(week/month),but i,ll say this:give me quality professional tools(heads up-Cranesong Avocet monitor controller/DAC) + active monitors above certain price and i,ll be happy man. Good luck.

Thanks for the brief post Niki (haha), I appreciate the time it took and the thought that went into it. I have spent the last week casually demoing a number of monitors (luckily I live in Southern California and LA has its share of pro audio dealers. None of them have ideal rooms or associated equipment but they are friendly and appear truly interested in helping, albeit the over/under on body piercings apears to be 10.

At the end of the day, i will try a few pair at home to see what's up. I really liked the Genelecs and the Dynaudios but I cant believe the sound coming out of the small enclosures. I will post my findings and will likely be burned at the stake as a witch but there seems to be EXTREME value to be found. Peace.
