The largest consumer audio show in America's Southland, AXPONA (Audio Expo North America), returns to its roots when it opens in Jacksonville on Friday March 9. The three-day show, which launched in Jacksonville in 2010, has happily switched locations from a "not-ready-for-primetime" venue to the more upscale Omni Jacksonville.

What the hotel offers audiophiles, besides its amenities and lovely waterfront, is its neighbor across the street, Jacoby Hall in the Times-Union Center for the Performing Arts. Home of the Jacksonville Symphony Orchestra, the hall's much touted superior acoustics—mezzo-soprano Frederica von Stade has called them "sensational"—offer attendees the opportunity to refresh their ears with the sound of a live, unamplified orchestra in a very special hall. What better way to tell if the audio systems you're hearing present a reasonable facsimile of the real thing?

While listening to Boston Acoustics' A 25 loudspeaker ($299.98/pair), I kept thinking about magic.

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.

The two-way Energy CB-10 ($269.99/pair) is a bass-reflex design. A large rear-firing port has an internal diameter of 2" and flares out to 2.75". The speaker uses a 1" aluminum-dome tweeter and a 5.5" woofer with a ribbed elliptical surround, the latter said to increase excursion, decrease distortion, and create a larger piston area for greater efficiency, making the CB-10 an easy match for amplifiers. The CB-10's frequency range is listed as 66Hz–20kHz, its in-room sensitivity as 90dB, and its nominal impedance as 8 ohms. In Energy's Convergent Source Module design, the tweeter and woofer are meant to act as a coincident source working together to provide wide bandwidth, constant dispersion, and a flat frequency response. In theory, this would all add up to easy setup and satisfying listening from anywhere in the room.

Last week, I had the honor and the pleasure of interviewing Bill Frisell in front of an audience—in what’s called a “Jazz Conversation,”—at this year’s edition of the Portland Jazz Festival. Held at the Art Bar in the Portland Center for the Performing Arts (PCPA), our chat was podcast by the Oregonmusicnews.com and can be heard here.
