GTO

Outline’s concept for GTO is to produce a large format line-source loudspeaker system that is flexible, adaptable, easy to use, and which provides audio performance that meets the demands of the most discerning engineers, rental companies and production managers.

An essential design element on the GTO is its V-shaped front baffle, for which Outline was awarded an international design patent. This ground-breaking design allows individual sound sources to be positioned, when couple in an array, much closer together.

GTO cabinets contain ten transducers in a compact cabinet with an internal volume of just 340 litres. It also features four 3-inch diaphragm compression drivers, four 8-inch mid-range drivers and two 15-inch cone transducers for low frequency range.

GTO C-12

The Outline GTO C-12 is a compact line-source enclosure designed to provide a flexible, powerful, and almost infinitely configurable loudspeaker system for professional sound reinforcement applications. It has been developed in response to customer demand for a multi-purpose loudspeaker system that can be efficiently transported and deployed, but still provide the power, intelligibility, and control necessary.

GTO-C12 develops the high transducer density concept pioneered by GTO by packing eight drive units into a remarkably compact cabinet, containing two 12″ low frequency drivers, four 6.5″ midrange units and two 3″ throat compression drivers.

The C-12 cabinet is 21.6% smaller in the vertical plane than the GTO, while overall cabinet weight has been reduced by a remarkable 30%.

GTO-DF

The GTO-DF is a proprietary ‘Down-Fill’ enclosure incorporating a newly designed waveguide based on phased audio paths. It is engineered to provide exceptionally high-quality sound to the first several rows of the audience at an event, filling the sonic gap often experienced by event attendees who are seated near the stage.

GTO-DF is mechanically identical to, and acoustically matched with, the GTO full-range cabinet, so it can be easily added to a flying array. Unique to the GTO-DF is a vertical dispersion range of zero-degrees to minus 25-degrees to ensure precision aiming of the sound into the audience and not onto the stage.

The GTO-DF is intended for large-scale applications, as part of the GTO-turnkey solution.

GTO-LOW

The GTO-LOW is bass extension cabinet which features the same dual 15” drive units, physical dimensions and rigging hardware as the GTO cabinet. The reflex ports are also in the same configuration as GTO which preserves the low-frequency continuity of the array when cabinets are combined. This allows combinations of GTO and GTO-LOW to be deployed in a wide variety of ways depending on the application, venue and available space.

The GTO-LOW is designed to fulfil two main roles as a bass-extension cabinet for GTO and as a multi-purpose low frequency array element which can be used with other Outline systems including Mantas and Butterfly.

GTO-SUB

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.

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.

Mantas 28

MANTAS 28 is one of the most recent Vertical Line Array element designed by Outline. Thanks to the great experience accumulated with Butterfly – the Outline system with the same fundamental components and characteristics – MANTAS 28 offers leading edge performance from a cabinet that is extraordinarily compact and lightweight.

Its top-grade components – two 8-inch midwoofers with Neodymium magnets and a 3-inch compression driver loaded with the well-known D.P.R.W.G. – ensure insignificant distortion levels and greater reliability.

In simple operational terms, Mantas 28 can best be described as a ‘compact, medium throw’ line-source system, delivering exceptional intelligibility, headroom and power up to around 60 metres depending on location and configuration.

DBS 18-2

The DBS 18-2 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 DBS 18-2 to obtain a wide passband and a considerable extension towards the bottom end of the frequency response.

The DBS 18-2 is primarily intended for large-scale applications, although it is also ideally suited to projects that demand no-compromise audio quality. The DBS 18-2 addresses an increasing demand for accurate, high-definition bass reproduction.

LAB 21 HS

LAB 21 HS is a loudspeaker system suited to high-quality sound reinforcement of infra-low frequencies. It comprises a NdFeB 21” long-excursion woofer magnet. Loading is a hybrid waveguide indirect radiation system able to completely recover low frequency sound pressure emitted from the rear of its 21” woofer, which means an increase in sensitivity of 6 dB SPL.

In other words, with the same input voltage, this system gives an additional 6 dB over the entire low frequency band compared to the same speaker used in a closed cabinet and, on average, an additional 3 dB compared to what the same speaker would give at low frequencies if used with a horn-loaded, reflex or band-pass system.
