GT 2X10 L.A.

Totally designed, manufactured and optimized in Spain, exclusively using European components.

Description

GT 2X10 L.A. is a 2-way Line Array system of high performance equipped with two (2) speakers of 10” in a tuned enclosure. The HF section has two (2) compression drivers of 1”  coupled to a waveguide. The transducer configuration generates a symmetric and horizontal dispersion of 90º without secondary lobes over the frequency range. It is the perfect solution  as main P.A, frontfill and sidefill in outdoor events or permanent installation.

MOUNTING INFORMATION

• T-S parameters are measured after an exercise period using a preconditioning power test. The measurements are carried out with a velocity-current laser transducer and will reflect the  long term parameters (once the loudspeaker has been working for a short period of time).
  ** The Xmax is calculated as (Lvc – Hag)/2 + (Hag/3,5), where Lvc is the voice coil length and Hag is the air gap height.

FREQUENCY RESPONSE AND DISTORTION

Note: On axis frequency response measured with loudspeaker standing on infinite baffle in anechoic chamber, 1W @ 1m

Inside GT 2X10 L.A.

GT 2X10 L.A. is also composed by a constant directivity horn specifically designed to work with two Pro DG Systems compression drivers of 50 W RMS which are coupled to a  waveguide. The constant directivity characteristics of this model ensure the ability to cover 90º wide horizontally and 20º wide vertically, at virtually any frequency within its operational  range. To ensure freedom of resonance, this flare is constructed of cast aluminium, with flat front finish to facilitate flush mounting.

KEY FEATURES

• Designed to work with two (2) Pro DG Systems compression drivers of 50 W RMS.
• It provides uniform response, on and off – axis with a neutral and natural frequency reproduction
• Coverage angles of 90º in the horizontal plane and 20º in the vertical plane
• Precise directivity control in the pass band
• Cast aluminium construction

TECHNICAL SPECIFICATIONS

Inside GT 2X10 L.A.

GT 2X10 L.A. is also composed by two Beyma compression drivers of 50 W RMS which are coupled to a wave guide. Specially designed under our own parameters for the best  performance of the system.
A combination of high power neodymium compression driver with waveguide provides the best junction for the best performance of GT 2X10 L.A. solving the hard problem of achieving an optimum coupling between adjacent high frequency transducers. Instead of using expensive and troublesome wave-shaping devices, a simple but effective waveguide transforms the  circular aperture of the compression driver into a rectangular surface, without undue angle aperture to provide low curvature to the acoustic wave front, arriving to fulfil the necessary  curvature requirement for the optimal acoustic coupling joint between adjacent sources until 18 KHz. This is achieved with the minimum possible length for low distortion, but without  being excessively short, which would cause strong high frequency interferences.

• 4” x 0.5” rectangular exit
• Neodymium magnetic circuit for high efficiency
• Effective acoustical coupling up to 18 KHz
• True 105 dB sensitivity 1w@1m (averaged 1-7 KHz)
• Extended frequency range: 0.7 – 20 KHz
• 1.75” voice coil with a power handling of 50 W RMS

HORIZONTAL DISPERSION

VERTICAL DISPERSION

Notes: dispersion measured with two waveguides coupled to a 90º x 5º horn in anechoic chamber, 1w @ 2m.
All angle measurements are from the axis (45º means +45º).

DIMENSION DRAWINGS

Note: * Sensitivity was measured at 1m distance on axis with 1w input, averaged in the range 1-7 KHz

CONSTRUCTION MATERIALS

Rigging Hardware

The magnetic pinlock is an innovative security fixing which avoids its loss and allows an easy fit with the flight hardware thanks to its magnetic properties.
Rigging Hardware for GT 2X10 L.A. Composed by: a lightweight steel frame + 4 magnetic pinlocks + a shackle to support a maximum weight of 1.5 tons. It allows raising up a total of  16 units GT 2X10 L.A.

Flight hardware incorporated into the cabinet with different angulation grades.

Stack mode for the maximum versatility and coverage.
VERY IMPORTANT: a misuse of the frame and components can be motive of cracking that could compromise the safety of an array. Using a damaged frame and components could cause serious mishaps.

Prediction software.

In Pro DG Systems we know that making high quality speakers is an important part of our job. Then, offering the warranty of using speakers properly is another part which is also  fundamental in our job. Good tools make the difference for an optimal use of the system.
With Ease Focus V2 prediction software for GT 2X10 L.A. we can design different configurations between systems and simulate their behavior in different places and circumstances like  obtain information of: coverage, frequency, SPL and general system behavior in an easy and comfortable way. It is easy to handle and we offer training courses for Pro DG Systems users. For more information, consult our technical service at: sat@prodgsystems.com
