Flysub 15是为Outline (欧浪) EIDOS 265无源线阵扬声器系统（如图所示）增加清脆而细腻的低音冲击而设计的。 事实上，FlySub系统是通过业界对延伸低音扬声器的需求设计生产的，它共享了Outline (欧浪) 的中频线阵列系统的声学特性和安装硬件（FlySub的iMode版本与Mini-COM.PASS iMode阵列兼容）。

FlySub 15超低音音箱配备了长冲程15寸扬声器，专门用于低频扩声。 集成到FlySub箱体的吊挂件与

Eidos-265完美兼容，这样确保了在尽可能最快的时间内完成安装。 考虑到特定极大阵列安装上的机械应力，箱体的倾斜线可以在极大阵列中实现更宽范围的几何配置，从而确保吊挂系统的必要安全裕度。

FlySub的声学负载被计算为包括上部低音频率范围的最高端，与EIDOS 265完美匹配。这减轻了箱体的低音负荷，从而以最小的失真产生更大的系统动态范围，并产生更高的整体声音质量。 为了达到这些效果，双层的15寸扬声器，使系统坚固，经久耐用，确保多年来一直保持一致的性能。

频率响应从35Hz到550Hz（-10dB），峰值声压级在140.5dB。 FlySub 15无源低音音箱是为搭配新款EIDOS 265线阵列而设计的，EIDOS 265也是一个无源音箱，需要一个外部功率放大器和DSP处理器（Outline (欧浪) 的T-Five DSP）推动。

FLYSUB 15 is a passive subwoofer specifically designed to reinforce the low-frequency response in an EIDOS 265 LA array. It features a single 15” woofer (76 mm voice coil and double spider), customized to produce very low distortion figures at both low and high output levels. This transducer design is the result of an all around project approach and continuous cooperation of Outline with the loudspeaker manufacturers. The transducer is loaded in a bass-reflex enclosure and is mounted on an oblique baffle: this gives the loudspeaker a secondary loading which improves the overall tonal balance, making the FLYSUB 15 the right solution to extend the frequency response of a two-way MF/HF array. The accurate placement of the reflex ports, on the same baffle, eliminates air turbulence noise, allowing a superior sound fidelity, even at higher SPLs.

The FLYSUB 15 is able to handle up to 500 W AES and 2000 W peak at 8 Ω. The suggested amplifier is the Outline T5-DSP. Up to two FLYSUB 15 can be connected to the same output channel. Each enclosure has two NL4 connector wired in parallel.

The integrated suspension hardware is a combination of top quality material and treatment in order to ensure extremely high resistance to stress, corrosion and abrasion – resulting in a simple, effective, and light weight rigging system. The angle between the enclosures is selectable from 0° to 8° with a 1° steps and up to six FLYSUB 15 can be flown in the same array. It is possible to create arrays of EIDOS 265 LA and FLYSUB 15, keeping the total array weight under the stated limits.

The cabinet is built from high-quality birch plywood and strengthened by the internal structure and thus is free from harmful colouring due to internal resonances. A sturdy steel painted grille, internally covered with acoustically-transparent foam and braced with two reinforcement bars provides superior physical protection for the components housed within the front of the cabinet. Four recessed handles facilitate the handling and dedicated flight-cases make the transport easy and safe.
