ג'ון אטקינסון בסיכום הביקורת על האקפלה ויולנצ'לו מלפני כמה שנים, כדי לתת פרופורציה ולהזכיר שלמרות שלאקפלה יש רמקולים ממש מצויינים, אלו רמקולים מאוד מסויימים ויש להם את האיפיונים שלהם וגם את המגבלות שלהם ולפני הכל צריך לאהוב פרזנטציה של שופרים ולא כולם אוהבים. ׁ
Summing Up
The Acapella High Violoncello II is the most expensive loudspeaker I have had the pleasure of using in my listening room. With its ionic tweeter and the use of horn loading for its upper-frequency drivers, it is also the most unusual. But it is superbly engineered and massively well constructed, and offers equally superb sound quality, with well-controlled lows, a natural-sounding midrange, well-defined and stable stereo imaging, and dynamics to die for.
That ionic tweeter offers a high-frequency clarity that is rarely equaled by conventional drive-units, but even at the factory setting, its sensitivity is a little too high for a completely neutral on-axis response. This will not be an issue in a large, well-damped room, but results in too much energy in the top two octaves in smaller, more lively rooms such as my own, particularly when driven by a typical solid-state amplifier, where the low frequencies will sound slightly lean. Driven by a tube amplifier with its typically higher source impedance, the High Violoncello II's low frequencies warm up and are in better balance with the speaker's high frequencies.
A few days after I write these words, the Acapella speakers return to the distributor. I shall miss them. Highly recommended for those with deep pockets and large rooms.
