Paul Messenger introduced Boston Acoustics' A Series in the April 2011 "Industry Update." With the creation of the A Series, Paul reported, BA wanted to create a "global loudspeaker," one that would be appreciated by music lovers worldwide.

Quiet, please, Mr. Olsen is about to describe the disadvantages of multiple–drive-unit systems. "The radiating surfaces must be separated by a finite distance, with the result that this system will exhibit peculiar directional characteristics in the overlap region where the sound radiation issues from both sources. To reduce this effect to a minimum, the overlap region must be confined to a very small range which requires an elaborate electric filter system for allocating the frequency bands of the units. The greater space required for the two loudspeakers is another important factor. The cost of two separate field structures and vibrating systems will be considerably greater than that of a single unit."

The enormous sky above Brooklyn's Prospect Park was a dazzling watercolor. Warm, soft shades of yellow, orange, and violet swept across a saturated canvas as the sun slowly dissolved into the horizon and day reluctantly gave way to night. It was the second week of August and, though no one wanted to admit it, the days had become noticeably shorter.

I walked alone through turnstiles that led to the large band shell where thousands of people would congregate for the final night of "Celebrate Brooklyn," a summerlong series of outdoor concerts. This year's season included performances by a wonderfully diverse and talented collection of artists—some obscure, some renowned, all worthwhile: Andrew Bird, Larry Harlow, Animal Collective, Real Estate, The Feelies, Los Lobos, The Bad Plus, Dr. John, and dozens of others.

Instead, most speakers work this way: Complicated electronics split the audio signal into pieces, adding various colorations and phase shifts along the way. The pieces are distributed to different drivers, each of which adds another unique set of characteristics. We then expect these fragments of electronic signal to be brought together again in a continuous, coherent reproduction of music. We agonize over different cable routings or which contact cleaner to use, and yet we calmly accept this grotesque sausage-making way of building speakers. It's ludicrous.
