Review: Acapella Triolons Speaker


Category: Speakers

I currently own the Acapella Campanile Highs and have used them as a reference for about three years and hear Acapella Violins weekly at a friend's home. The remainder of the equipment and speakers were auditioned over a 30 hour, 3 day listening session. All amps mentioned and all equipment listed were listened to on the Triolons, carefully varying one component at a time with the Triolons remaining the one constant during the 3 days. The other speakers listed with the exception of the Campaniles and Violons were auditioned during the same weekend with the same equipment but for much shorter periods. The Coltrane Supremes were breaking in; the Coltranes were fully broken in.

The Triolons are an imposing sight. Two woofer towers, each 14" by 28" by 7' tall, each weighing 650# plus a cross piece holding a plasma tweeter attached to the woofers and a sword bearing two horn loaded speakers, one horn 30.5" in diameter, the other 18.5" in diameter. The Triolons can be driven by a single amps of 18 watts or higher power but must be triwired and have an efficiency of 97 db. Each side weighs 850# total. The crossover points are 200, 700 and 5000 hz.

The sound from 200 hz up to 40,000 hz emanates as a spherical wavefront. The Campanile Highs are similar but crossover to their woofers at 500 hz, use the plasma tweeter plus a single horn and are much lower in efficiency (92 db). The Triolons are typically a 6 ohm speaker but have an impedance at 30 hz of 28 ohms. The same is true of the Campaniles. Neither is a particularly easy load for an amp to drive; however the greater efficiency of the Triolons does open up the possibility of driving them with the right low power amplifier.

In my experience it takes a high power, high current, low output impedance amp to make the Campaniles come alive, with the exception of the Einstein OTL's which are used at the Acapella factory and do an admirable job of driving both speakers. The Triolons are much easier to drive than the Campaniles, but also more revealing of the associated equipment used to drive them. Different combinations of equipment resulted in different tradeoffs. Generally, the more expensive set ups involved fewer tradeoffs.

Another Audiogon poster has developed a nomenclature characterizing various pieces of equipment using the terms "workhorse", "realistic", and "magical", with magical suggesting that the system does some things so well that it results in a suspension of reality - you are no longer listening to reproduced sound in your room, but are somehow transported to the event. I have a bad tendency to think/listen in terms of how well a system does certain things and how well it avoids doing things which irritate me, which is to say that I have a bad tendency to focus on the pieces rather than the whole. In those rare instances when a system is so good that I stop analysing the sound and just listen to the music, then I know that something is right.

I am told that my initial reaction to listening to music on the Triolons was to stop talking and get a silly grin on my face. I don't know about the goofy grin but I do know that I did not say a word until the piece of music ended. If you know me, that says alot. I have now lived with the Campanile Highs for a number of years and they are by a significant margin the best speaker that I have ever owned. They are a difficult speaker to make work properly. They require a large room and are hard to drive. Amps that drive the woofers well do not ever seem to work as well on the midrange horn and plasma tweeters. The happy medium is either the best solid state amp which you can find or an OTL with at least 60 real watts of power (read the Einstein). The two types of amps sound different on the Campaniles and have different strengths and weaknesses.

The prime goal of the Acapella design team on the Campaniles was to get the best match between the woofers and the midrange horn and not the most extended bass response (the Campaniles are reasonably flat down to about 40 hz but drop off rapidly after that).

All of this is a prelude to talking about the sound of the Triolons. What makes the Triolons special? In many systems the soundstage is either localized between the inside edges of the speakers or perhaps extends to the outside edges of the speakers. With the Campaniles and the right equipment you can get a soundstage that extends from wall to wall and has excellent depth. Focus and image specificity are good but never pinpoint. Image size is believable, i.e. no sopranos with mouths the size of a baby grand. If the Campaniles have a problem in this area, it is that without proper set up and the right equipment some frequencies can localize on the horns. This is most problematic during the time when the speakers are breaking in but can happen with the wrong wire or associated equipment and is set up dependent.

The Triolons create a massive soundstage with huge amounts of air and space. The sidewalls of the room from the plane of the speakers and the back wall disappear. Instead of recreating the recorded venue in your room, the room no longer seems part of the equation. Its almost as if the space where the event occurred is appended to the end of your room and the recorded event is occurring there ( note that this is only true with certain recordings made in large halls and properly recorded and not with every piece of music played or with all associated equipment or wire). Imaging and focus are quite good but edges are a bit diffuse as in real life. Images are very three dimensional and fully fleshed out

A friend is driving Watt/Puppy 6's with MacIntosh 501's. This combination has great punch in the midabss. My Campaniles with my equipment never had this degree of punch in the midbass. With the Triolons this is no longer the case. Their midbass is extremely detailed, fast and well controlled with excellent slam.

The Campaniles will play loud and are very dynamic from pp to fff. The same is true of the Triolons but much more so. The Triolons significantly extend the dynamic envelope with excellent microdynamics and crescendo's capable of rattling walls, all with a vanishingly low level of distortion. Detail retrieval, particularly low level ambient detail is phenomenal. I am simply hearing low level detail that I never knew existed on familiar pieces.

The Triolons are very coherent and seamless. They have an effortlessness that is reminiscent of the Goldmund Reference TT which I owned for several years. Images have a solidity and three dimensionality. In comparison to the bass of the Campaniles, the bass of the Triolons is tighter, better controlled, goes lower with more authority and is faster with greater retention of harmonics. More importantly, by pushing the horn technology down to 200 hz and dividing the range between 200 hz and 5000 hz so that it is handled by two horns, there is a significant lowering of intermodulation distortion that effects the entire range. Acapella has been able to do this in such a manner that the two horns act almost as a single unit. You cannot pick out the crossover point and there are no discontiuities as the sound moves between the horns. Bells and other percussive instruments have a steep leading edge with a with a natural reverberrant tail. In this area, the Triolons remind me of the Colibri cartridge. Voices are a joy on this speaker, both male and female. The plasma tweeter remains the best high frequency driver that I have heard and that includes the superb diamond tweeters used in the Martens and Kharma's.

Finally, a word about amps used during auditioning. All the amps mentioned at the end of this review were excellent. For my particular tastes the Lamm ML2 at 18 watts and the Audionote Kegon at 20 watts stood out. I hope to have a pair of the Einstein 60 watt OTL's sometime this spring for comparison. Note that the Edge Reference was also excellent at significantly more power. With the Triolons, it is more the quality of the amplification than the power (although 18 to 20 watts is a minimum). Also note that the Jorma Prime cabling proved an excellent match for the speakers, although the Valhalla speaker cable was excellent. With solid state amps, particularly the Edge Sigs, a tube linestage sounded best.

My listening preferences are about 50% classical, the remainder jazz, acoustic and 60's and 70's rock. One CD that served as a reference for system changes was the soundtrack from American Beauty, particularly the first two tracks. We also played a number of Verve recordings from the 50's, rock from the 60's and 70's and quite a bit of voice.

Ultimately the enthusiasm for a product reviewed is best determined by whether or not the reviewer is significantly enough effected by the product reviewed to buy it. I am currently working on arrangements to buy the Triolons.

As I mentioned in the body of the review, I was able to hear the Triolons with a variety of front ends, amplifiers and cables and to hear a number of other speakers driven by various combinations of the same equipment. This marathon listening session is more fully detailed at www.audiofederation.com/blog/ which includes pictures of the Triolons and some of the other equipment; consequently, no real point would be served in rehashing the same information. However, I would like to make several observations on the amps used with the Triolons and the effect that the amp used ultimately had on the sound.

Edge Electronics NL Reference "paramid" 800 watt solid state amps: the Reference was tubelike (here I mean classic tube sound). The highs were somewht soft, the bass somewhat less controlled, particularly from the mid bass down, very sweet and three dimensional with good detail and transparency and excellent dynamics. There was a tremendous sense of air and space. Image height was excellent. This was one of only two amps that made the side and back walls disappear. Imaging was never pinpoint but was very natural. This was one of my favorite amps on the Triolons, even though most of the other amps were more neutral. Think big and lush and fun to listen.

Edge Electronics Sinature One (400 watts): more detailed than the NL Reference, tighter bass, more accurate frequency response, more transparent but unable to recreate the sense of air and space that the NL Reference amps created. Lower image height, smaller soundstage, more pinpoint imaging but not as lush as the NL Reference. Very accurate but not as emotionally involving or fun.

Lamm ML1.1 90 watt push pull amps: closest sonically to the Edge NL Reference, but with flatter frequency response, but less power in the bass. The bass is tighter than that of the NL Reference. The ML1.1 has a better sense of depth and imaging than the Edge Signatures and a better sense of air and space but the air and space never equalled that of the NL Reference. This was a very nice amp and the best bargain of the amps used on the Triolons. This amp uses solid state rectification. Never as emotional or lush as the Edge NL. The micro dynamics were exceptional.

Lamm ML2 monos, 18 watts per channel, single ended, tube rectification: these amps are extremely dimensional with an excellent sense of air and space; very good in differentiating drum heads; excellent image height; very delicate and extended top end; very harmonically neutral; really glorious midrange; not quite enough power on big music like The Gladiator, but otherwise glorious; very clean with vanishingly low distortion; very sophisticated and emotional. Clearly and by a fairly significant margin, the best amp on the Triolons of the ones mentioned thus far.

Audio Note Kegon amps, 20 watts, single ended, tube rectification: clearly and by an audible margin the best sound heard on the Triolons during the entire listening session. How can a 20 watt tube amp have better control of the bass of the Triolons and better micro and micro dynamics than the two Edge solid state behemouths? This was the best bass of any of the amps auditioned, effortless. There was not a single area in which the other amps beat the Kegon. A truly synergistic match for the Triolons. I was told by the owner that the magic was in the silver wire transformers.

Further thoughts: I hope to hear the Einstein 60 watt mono OTL's in the spring.





Some additional technical information: the crossover point from the woofers to the midrange horn for the Campanilies is 700 hz so that the frequency range from 200-700 hz is being handled by the four 10" SEAS drivers which also handle the lower frequencies. The same 200-700 hz range in the Triolons is covered entirely by the 30.5" horn. This difference has major consequences in the sound of the two speakers as detailed in the review. The impedance curve for the Triolons is essentially 5 ohms from 100 hz up to the limits of audibility; however, there is a very narrow Q peak at 30 hz of 28 db which rapidly decreases to 1.9 ohms at about 70 hz and then flattens out to 5 ohms by 100 hz which makes the Triolon very amp sensitive, particularly below 100 hz.
I travelled to Sacramento on Sunday to help uncrate/set up my Campaniles in the home of the audiophile who bought them. This allowed me to finalize the purchase arrangements for the Triolons which should arrive sometime after CES. This also allowed me to hear the Campanile Highs in another system which in some ways was very different from mine. The components in the buyer's system included the latest versions of the Zanden transport and D/A with the latest clock, Levinson 33 amps, an Audio Research Ref 3, Transparent Opus interconnect and speakerwire, a Krell subwoofer, and a full Isoclean AC set up in a room about 30% larger than my listening room.

The Krell is extremely flexible and crossed over at 60 hz mated seamlessly with the Acapella's. The Levinson amps also mated exceptionally well with the speakers as did the Opus speakerwire. The 33's tonal balance (at least in this system) was different from that of the Parasound JC-1's, more biased toward the midbass, darker, richer but not as extended at the very top, somewhat slower and less detailed but with excellent depth and good focus. All in all the amps and the rest of the system complimented the sound of the Campanile's.
After many months of weather induced delay, the freight company delivered my Triolons last Saturday (3 very large crates, 2@200# each and one at a whooping 1500#). The crates are currently in my garage awaiting the piano movers who will come in this weekend and move the speakers into the house. Given that each of the woofer towers weighs 650#, this seemed prudent. Hopefully I will be able to get the Triolons up and running over the weekend.
