AVinci One




AVinci One with the finest units and audiophile crossover parts.




Review from a customer in the US...
I acquired this pair of Acoustic Reality AVinci One speakers based solely on the fact that their drivers were something you usually see in much more expensive speakers (we are talking about many thousands of dollars here). When I initially listened to them out of the box, I was very impressed with their bass extension and their driver integration, thought that their upper midrange was a little layed back, with the little woofers were having to work hard to produce really deep bass, sounding slightly mechanical, but very impressive none the less.

I don't think I was prepared for the improvements that occurred to the AVinci's after the 400 hour mark though . Of all the speakers I've owned, only Magnepans have changed as much in sound from their initial listen to full break in. To say that I am now completely overwhelmed by this little speaker is putting it mild. The slight mechanical nature from the speaker's little woofers has completely disappeared, with bass just flowing from the speaker. They image as good as anything that has come my way, with a very layered soundstage, allowing the speakers to completely disappear. The treble performance from the speakers has reset my view of what a dome tweeter is capable of, with the highs being very smooooth indeed. I had never heard the Hiquphon tweeter before, but I have to agree with Peter, that it must be one of the best sounding dome tweeters out there. Back to the AVinci's bass performance: They have the lowest bass I've ever heard from a monitor speaker bar none! I'm sure that other speaker monitors which use the larger Scanspeak Revelator woofers must have even lower bass, but the Avinci's bass is just amazing for its size!

If I had to find something to criticize about these speakers, I guess I would say that their sensitivity is on the low side, requiring a bit of power to really rock. But with my custom amps only having sixty watts per channel, they still have no problem getting these speakers loud enough to do the trick. The Ones just are less efficient than other speakers that I've owned.

As an Electrical Engineer myself who has been deeply involved in high end audio for over twenty years, I still can't figure out how Acoustic Reality can bring this level of speaker to market for $1000. This speaker is my current my reference bang for the buck monitor. The AVinci One has exceeded all of my expectations, which were quite high.

How do you find accuracy of the AVinci One? What about clarity and details?
Accuracy and detail extraction are the strongest points of the Avinci One. They are truly a reference level product, that should be compared to the best monitors available, regardless of price (in my opinion).

These speakers have allowed me to discover new details in many of my CD recordings, that I never knew existed when I've listen to them with other speakers. I have previously listened to these same recordings (extensively) on the following reference level speakers: Alon V, Legacy Whisper, Dunlavy Aletha, IVa & V, Proac 2.5, Magnepan MGIIIa, Spica TC-50, Spica Angeles and Theil 3.6.

Like I said before, this speaker has exceeded my expectations of what a monitor is capable of doing.




Feeback from a customer in Italy...
I have compared the AVinci One with ProAc Response One. The AVinci One win in all aspects!!!

These speakers are very little big jewels. The bass go better and better. The rest too. Are incredible. Almost disarming, awesome. :-)

Feedback received a few days earlier from the same customer:
This afternoon I have listen the One's for about one hours.
I thought: 1) Where is the sub? I don't remember that I have one...2) Disarming...I am listening what I see or I am listening an invisible floor standing speakers? !!! :-) Their naturalness is unbelievable. The tweeter is great. The woofer also but I was prepared. There is not discontinuity between drivers, all is fluid. The bass frequencies go better minutes after minutes and so the high frequencies. The stage is incredible for dimension and neutrality.




Feedback from a customer in Asia...
I'm still breaking in my AVinci One but I am blown away by how much detail these speakers are passing through! And, by detail, I mean the nuances of the performance, not fatiguing treble. Just this morning, in spite of being half asleep, I heard details in several classic 80's songs that stopped me in my tracks wondering "where did that come from?"

Other comments: Dynamics and treble extension are quite good, as is the bass. Midrange is smooth and voices sound very very natural. Treble is extended but not brittle or grainy (well, there's a bit but consider my cd player and amp). I've heard that it takes 500-700 hours to really break in these speakers. It took almost 200 hours (I'm guessing) to clear up the mud in the bass; initially dynamics and treble extension were also very closed-in and constrained.

I've got the Avinci's breaking in with my old NAD receiver and CD player, set up on flimsy stands on one side of my bedroom. One speaker is firing straight ahead, the other is in a corner toed in at a 45-degree angle! So, if they sound this good in such horrible conditions with mid-fi (at best) equipment, imagine how they will sing when hooked up to quality components! More to follow...





The cabinet is made MDF - 22mm baffle and 19mm sides. It is 6.8 netto liter.  The height is 11,5", the depth is 9,6" and the width is only 7". The bass reflex port is positioned on the rear side.

AVinci One
AVinci One is a true High-End reference studio monitor loudspeaker.

The AVinci one contain one of the best tweeters available. The tweeter is OW1 from Hiquphon which is called the best dome tweeter in the world of some High-End magazine reviewers; we and our AVinci One customers do understand why! The Hiquphon tweeter is without ferro fluid oil like the Vifa ring radiator tweeter and the Scan Speak 9700 tweeter. The hiquphon the tweeter is working like a ring radiator in the higher frequencies, because of its physical size and the way it is handling the acoustical phase of the higher frequencies.

The mid/bass unit is REVELATOR 15W/8530k00 from Scan Speak. It is the best 5.5" mid/woofer in the world. Because of the size and the worlds best 5.5" unit the speaker has a very fast transient response / attack.

AVinci One - shielded version
AVinci One is also available in a shielded version to be used as center speaker in surround systems, when using the AVinci One as front speaker.

AVinci One measurement:
The crossover has been fine-tuned to let the speakers be full phase coherent and to reproduce a full three-dimensional soundstage. This means that listening tests have been used to select the final optimal sound. Both Tube- and Solid State amplifiers have been used through the long crossover fine-tuning. The speaker has been listening tested in three different rooms - a small and very hard room without any damping - a true listening room with damping - a large room without any damping.

Click here to see the on-axis frequency response. The off-axis response is when the speakers are pointing directly to your ears (not optimal and not optimized for on-axis listening). The cyan curve is unsmoothed measurement result - the red curve is the smoothed measurement result.

Click here to see the off-axis frequency response. The off-axis response is when the speakers are parallel set up - the edges of the two cabinets are parallel to each other (to be used for optimal sound performance - the depth in the music and the three-dimensional soundstage are there).

Click here to see the off-axis waterfall plot. As you can see: No resonance's - everything is silent when "the water" is reaching -40dB.

Click here to see the near field measurement of the bass unit and the rear bass reflex port. The white curve is the bass reflex port. The yellow curve is the bass unit. If you imagine the complex sum of both curves then it shows the +-3dB point ( = -6dB point) is 40Hz. The -9dB point is 30Hz.

Click here to see the impedance curve. As you can see: An easy load to any amplifier - the absolute minimum impedance is 7.6 ohm.


AVinci One listening impressions and engineering comments:
The sound is "simply too good"! This is a very musical speaker and has a three-dimensional soundstage. The sound has soul and musicality. The sound is very warm, very transparent and very smooth. The tweeter is without ferro fluid oil and therefore extreme detailed in the upper octaves; the details of the instrument are amazing. The midrange is very realistic - the voices are very clear. The bass can go deep - you have not listen to any speaker before using such a small size cabinet playing the deep bass like the AVinci One.

You can expect a lot of this little speaker. The AVinci One is a little super model reference monitor with a huge sound.
