Vienna acoustic morzart

Reverse polarity on your tweeters.  They have push on connectors, if I recall, so just carefully remove the screws and tweeter and switch the push on connectors.  Several of us Mozart owners have done this fix. The tweeter is good quality with a nice rich sound.  Great speaker for the money. 

I sold Vienna Acoustics at Tweeter & Magnolia & I sold many a pair of Mozarts 
without a return or complaint. I sold and currently own Sonus Faber Guarneri Homage, so I am very familiar with both brands. Regarding your Mozart experience, you either don't like the speaker or there is an issue with the tweeter. Tweeters can still make sound and be defective at the same time. If you are trying to compare the Mozart's to the Cremona, they are not in the same league. In other words, you get what you pay for. Most of the Mozarts that I sold at Tweeter were paired with receivers with no complaints  so I have hard time believing that they would sound bad with a Mac integrated amp. I happen to own a Mac stack too so I am very familiar with that brands performance and it does not roll off the highs. Both VA & SF were distributed in the US by Sumiko & and I participated in there master class for speaker set up. Both brands have silk dome tweeters that have a soft voicing that is more geared toward voice and strings. So depending on your preference & hearing, you may not like the Cremona because it to has a soft dome tweeter. The Guarneri which an Homage and step up from the Cremona does not have a dynamic sound but a harmonic richness that brings the emotion and human touch to the performance that goes beyond dynamics. That being said, neither the Mozart or Cremona is a good choice if Dynamics is your ultimate goal but if you are seeking the soul of the performance then biting the bullet for Cremona is the way to go. 

@stereo5, I've heard macs a few times I think but I never spent real time with them.  I'm just going by what many others say about the mac sound.

@jon_5912,
McIntosh does not have rolled off highs, what you are stating is a fallacy.  If you had heard a Mac you wouldn’t have made that statement. 

I've got a pair of the Mozart Grands that I got cheap at Best Buy when they dropped the line back in 2010.  They are finicky.  In my experience they can be very enjoyable but they can also be terrible.  They do very deep bass for their size but the tradeoff is that the quality of that deep bass isn't very good.  They are very room and placement sensitive.  I liked them best pretty nearfield because the small drivers don't have enough punch to sound natural from a distance.  

I've never had a Mac but my understanding is that they tend to be voiced similarly to the Viennas with rolled off highs and maybe somewhat softened bass.  I'd guess the combination would be too rolled off and too soft in the bass even for people who tend to prefer that sound.  

Good to know. I shall try. Thx again

I had a set and reversed the tweeter connections inside the speaker and viola! The highs were there now! I had read to do this on an audio thread.  

They are. I think I am trying to compare the Mozart with something that is in a different league. 

See if your tweeters are working.  Get up close!

Thanks that is good to know. Have you tried the Cremona M with a Mac and how does that sound?  I am looking for clear highs and mid. 

I own both pair of speakers.   The Mozarts and Cremona M’s are really in 2 different leagues.   The Mozart’s are a great speaker for their price and although they don’t have the bass (or bass slam) as the SFs , they should sound pretty good.  Are you sure they aren’t damaged?   Btw. I not a fan of the Macintosh sound, so my natural inclination would be to try a different amp.  I’ve run my Mozart’s using Accuphase, Hegel, and now First Watt.   The accuphase made them sing the best (sorry Nelson)
