  • Outline (欧浪) GTO-SUB是一款高效超低音音箱,使用2个18寸长冲程低频传感器。 采用了许多创新技术,提供优质的电声性能,包括超低功率的压缩和失真水平,在长时间内可靠地提供极高的声压级
  • 极高的输入功率(9600W AES峰值)和极高的声压级(在1m距离上产生147 dB峰值声压级)
  • 通过2个NL4(并联)和2个LKI-8(并联)连接
  • 配备高精确度、轻型的GTO吊挂系统,可以在标准(垂直)配置下吊挂16只音箱,如果项目应用需要各种不同的斜角或正/负倾斜, 可以吊挂多达12只音箱。 这两种情况都可以使用Outline (欧浪) 专利的“OpenArray”3D软件程序精确检查和调整配置
  • 音箱可以悬挂或堆叠在前方或面向后方,以便于创建心型阵列,增强低频的声场覆盖
  • 可选用斜角来优化阵列形状

  • Modular design with identical footprint to all other GTO system elements
  • The Outline GTO-SUB is a high-efficiency subwoofer featuring two 18” long-excursion low frequency transducers. It utilises a number of innovative technologies to provide premium electro-acoustic performance, including ultra-low power compression  and distortion figures, to reliably deliver very high SPLs over extended periods
  • Very high power handling (9600 watts AES peak) and sound pressure (147 dB SPL peak at 1 metre, half-space)
  • Connection through 2 x NL4 (wired in parallel) and 2 x LKI-8 (wired in parallel)
  • Equipped with the high-precision, light-weight GTO rigging system to allow a total of 16 cabinets flown in standard (vertical) configuration, or up to 12 deep if the application requires various splay angles or positive / negative tilting. In either case the precise configurations may be checked and adjusted using Outline’s proprietary ‘OpenArray’ 3D software program
  • The cabinets can also be suspended or stacked either front or rear-facing in order to facilitate a cardioid array and thus provide enhanced coverage control over low frequencies
  • Selectable splay angles to optimize the array shape


GTO-SUB是一款双18寸倒相式超低音音箱,结合多种创新的扬声器技术,使其能够在多年的最高水平上提供一致的性能。 箱体通过大面积长孔调谐低频。 这使GTO-SUB获得较宽带通,并且可以大大延伸低频。 使用这负载方法,分析技术和精心设计完全消除了与传统音箱相关的常见“端口涡流”。

GTO-SUB主要用于大型项目应用,是GTO整套解决方案的一部分。 非常适合需要不折不扣的音频质量的项目。 GTO-SUB满足了对于精确度、高清晰度低音重放的不断增长的需求。 该产品具有出色的电声功率转换能力,且密闭在紧凑箱体里。 精心选择反射排列和箱体结构,以便提高性能。 GTO-SUB可用频率范围在-10 dB为28 Hz~160 Hz,而在+/- 3 dB为34 Hz~107 Hz。 最大灵敏度为自由场97 dB,半空间103 dB。 2400W的最大连续AES功率在自由场的声压级为131dB,在半空间的声压级为137dB,而在半空间峰值声压级可达到147dB。

GTO-SUB箱体采用优质的18mm(酚醛胶合)波罗的海桦木胶合板制成,通过龙骨支撑减少箱体振动模式,提高箱体的刚性。 扬声器箱体外形的设计避免了内部共振。 表面采用防刮防水黑色喷漆处理和面罩采用反谐振钢网保护。 当与GTO主支架连接时,可集成吊挂多达16只音箱。 如果需要,可通过集成吊挂选择3°的斜角,根据声场覆盖要求调整吊挂音箱组的整体形状。

GTO推车“3只向上”的设计,有利于在平坦或不平坦的表面上装卸和运输。 箱体的侧面嵌入集成把手,在搬运过程中用于正面紧握。 防风雨保护罩也是整套方案的一部分 - 包装。 与扬声器的连接使用两种类型的连接器,成对并且全部并联连接。 分别是:两个NL4连接第一个低音扬声器的1 + / 1- 和第二个低音扬声器的2 + / 2- 接点,以及两个LKI-8连接第一个低音扬声器的A / B接点和第二个低音扬声器的C / D接点。

The GTO-SUB is a dual 18” subwoofer enclosure using phase inversion type loading, which, coupled with the use of several innovative loudspeaker technologies, allows it to deliver consistent performance at the highest levels over many years. The enclosure is tuned to a low frequency by way of a long port with a large surface area. This allows the GTO-SUB to obtain a wide passband and a considerable extension towards the bottom end of the frequency response. Analysis and careful design has completely removed the usual ‘port turbulence’ associated with traditional cabinets using this loading method.

The GTO-SUB is primarily intended for large-scale applications, as part of the GTO-turnkey solution. It is ideally suited to projects that demand no-compromise audio quality. The GTO-SUB addresses an increasing demand for accurate, high definition bass reproduction. This product is capable of outstanding electrical to acoustic power conversion but still within a compact package. The performance is aided by the careful choice of the reflex alignment and the construction of the cabinet. The GTO-SUB has a useable frequency range at -10 dB of from 28 Hz to 160 Hz, while the response is just +/-3 dB from 34 Hz to 107 Hz. The max sensitivity is 97 dB in free-field and 103 dB in half-space. The maximum continuous AES power of 2400 W gives 131 dB SPL in free-field and 137 dB SPL in half-space, while peak values can reach 147 dB SPL in half-space.

The GTO-SUB’s high quality build finish is constructed from 18 mm (phenolic-glued) baltic-birch plywood and includes bracing throughout to reduce box vibration modes and to increase the overall cabinet rigidity. The overall shape of the loudspeaker has been created to avoid internal resonances. The outer finish applied is a scratch-resistant, waterproof black paint and the front of the cabinet is protected by an anti-resonant steel grille. When used in conjunction with the GTO mainframe-bar, each element’s integral rigging allows up to 16 cabinets to be flown in standard applications. If required, a splay angle of 3 degrees can be selected via the integral rigging, thus allowing the overall shape of flown clusters to be adjusted according to the coverage requirements.

GTO trolley-board designed for ‘3-up’ aids handling and transporting on even or uneven surfaces. Recessed integrated handles in the side panels of the cabinet are used for a positive grip during handling. Weather protective shower caps also form part of the turnkey -package. Connection to the loudspeaker comes in the form of two types of connector, both in pairs and all wired in parallel. These are: two NL4s wired pins 1+/1- for the first woofer and pins 2+/2- for the second woofer, plus two LKI-8 wired pins A/B for the first woofer and pins C/D for the second woofer.
