The new E219 subwoofer joins the steadily growing line of Adamson Systems Energia Series (“E Series”) components that kicked off with the full-range E15 (15-inch) full-range line array module, later joined by the more compact E12 (12-inch) full-range line array module and E218 (dual 18-inch) subwoofer.
An Energia system is holistic and cohesive, as opposed to an assembly of individual, unrelated elements. All loudspeakers and subwoofers are expressly designed to work with networkable Class D amplification, DSP, cable and power distribution, software integration of control, and 3D simulation and diagnostics.
There are solid engineering reasons for providing turnkey rigs for touring, one-offs, festivals, and permanent installations. Approaching “system technology” as a whole helps insure a consistently high level of performance, delivers a known, quantitative reliability index, and offers the ability to provide software updates that future-proof the investment.
Specifically, all loudspeakers are powered by Lab.gruppen PLM 20000Q amplifiers with integrated Lake digital signal processing and Dante networking capability. Before shipping, the processors are equipped with a selection of optimized frame presets that cover the most common array and subwoofer configurations, while also accommodating differing array design characteristics.
The concept has proven to be quite successful in the marketplace, with Energia systems now a staple in the inventories of sound companies around the world, regularly deployed to serve a wide range of top-tier tours, festivals, and live events.
Lighter & Tighter
Extensive customer input indicated that the line would benefit with the addition of a musically exciting low-frequency experience, which served as the genesis of what would become the E219.
It can also be viewed as a superior successor to the T21 subwoofer, a dual 21-inch design developed for the legacy Y-Axis Series. To the point, the E219 was conceived to be smaller and lighter while capable of delivering high output and exhibiting improved efficiency in its intended bandwidth.
As the name implies, the dual cone drivers have been scaled down to 19 inches, a key factor in reducing enclosure size and weight. Further, the smaller, lighter drivers are able to produce a punchier, tighter LF sonic quality than their 21-inch predecessors while also displacing “more air” than 18-inch drivers.
The 19-inch format has proven to be an ideal middle ground between the two. Directly compared to an 18-inch cone, it provides additional piston area for increased power transfer, but only a very small increase in mass, hence the rapid and impactful response characteristics.
