Acapella Versus Avantgarde

Murray: I didn't actually "change" the Violon for another spkr. Rather, I kept my old spkrs (Genesis V, slightly modded) for two reasons:
- The cost: I *thought* I could manage the asking price -- but changing circumstances decreed that I couldn't
- (minor) Maintenance of the Ion tweet: very expensive to replace.
Otherwise, I loved the sound of these spkrs. The low end extension didn't bother me in the least (I wasn't considering the "extended suboctave" option at all): a dipole subwoof on either side blended in very well for extra energy below 50Hz. Most, if not all of the time, the subwoof wasn't mandatory for in room music enjoyment.
I found the tweet->horn integration excellent and the only cause for slight concern was the low end coupling with the horn(around 6-800Hz). Again, this is nitpicking..
I wouldn't say that the bass wasn't "tight" sounding in and of itself -- rather that coupling the horn with a dynamic woofer isn't easy and there may have been slight phase issues. In any case, I was confident that IF there was serious concern in that region, I could easily communicate w/ Acapella to solve the issue to my personal tastes quite easily & inexpensively (slightly alter the bass q...? X-over config? Change the driver for one with a stronger magnetic field? Many possibilities to play with).

Speaking for the rich, however:), the Campanile is the model to go with; the full intensity of a Mahlerian orchestra is easily felt...

According to the Aaudio Imports web site, the Acapella Violon ($35K) is twice the price of the AG Duo. By that alone, wouldn't you expect considerably more from it than the AG?

As Mike from Audio Federation suggests, the visual similarities between the two would beg comparisons. However, with the Acapella full horn line running from $26K all the way to $350K, it would seem that we're talking apples & oranges.

Those Acapella's sure are a work of art.

I am also an Acapella owner (Campagnile Highs), have a friend who owns Violon Highs and the new La Campanella and would like to address address several issues: i) maintenance of the plasma tweeter, ii) coherence of the drivers and iii) bass. In over four years, the tweeters have proved almost bullet proof. They have an automatic mode that turns them on only when a signal is running through them, thus significantly decreasing wear on the tubes and quartz rod that generates the plasma. In full time, 24 hour a day use, one might expect to retube and replace the rods after about five years. In the automatic mode, who knows? The tubes are user replaceable and dealers should be able to replace the quartz rods which are not hideously expensive.

Coherence. This is an area where Acapella has been very successful. The mating between the horn and plasma tweeter is extremely good to excellent. The mating between the horn and the woofer can be very good but is dependent on the amp used and on placement in the room and cabling. This improves greatly during break-in but it does take the woofers a long time to break-in/loosen up. As this happens, efficiency improves, the woofers play lower in frequency and are more dynamic. None of these (with the exception of the La Campanella) is really a near field speaker. They benefit from a larger room. In the wrong room with the wrong associated equipment, some sounds may localize on the midrange horn. Having said this, even the Campaniles benefit from a really excellent subwoofer but only with respect to the bottom octave. Acapella seems to have made a conscious choice to design for coherence over having the bottom octave. Normally this is not a problem, but with an really excellent sub there are gains in depth, image density and low end power where present on the software. This is a really easy speaker with which to listen to music.

As you might guess, the Acapella cables are a really synergistic match for the speakers. Acapella uses the Einstein electronics to voice the speakers at the factory and the combination is magical.

Thanks for the explanation Gregm - I have wondered what would move one on from Acapella's - no answer yet then! Hi to Fred too - good to see that you remain very happy with your Camapniles. Despite bothering everyone, over a few years, I still haven't made the jump. My room would be too small and up to now my electronics not up to the speakers, but I'm getting there slowly!

I heard the Avantgarde Trios with Basshorns just recently. I thought they were fantastic. I have Sound Labs and I didn't think the Avantgardes gave too much away in the areas of transparency and inner detail to the big electrostats. As far as integration and coherency goes, this all-horn system is seemless at all volume levels.
I can't see how a speaker like the Campanile could be as coherent across all frequencies at all volume levels when it is using 3 separate technologies. How four 10" dynamic drivers could keep up with a plasma tweeter when volume levels approach 100dB SPL is beyond me.
