POINT SOURCE speaker - which means you can point it and it is it’s own source … unlike an ARRAY which is meant to be part of LINE .. ARRAY speakers throw wide but not high .. Point source speakers throw a pretty even metric of sound.
The L-Acoustics X15 is a powerful and versatile loudspeaker family within the X Series, offering two variations: the X15 HiQ and the X15 HF. Both excel in live sound reinforcement and production applications, so let’s delve into their specifics:
X15 HiQ: (We have 12 of these)
15-inch low-frequency transducer and 3-inch compression driver: Delivers impactful and clear sound with accurate and controlled directivity. Enhances high-frequency directivity and reduces off-axis coloration, ensuring consistent sound quality across the coverage area.
High SPL (Sound Pressure Level): Up to 138 dB, ensuring clarity and power even in the loudest environments.
L-Vents™ laminar vents: Reduce port noise and allow for higher output without compromising sound quality.
Applications: Primarily used as a stage monitor for musicians due to its strong vocal impact and immunity to feedback.
Also suitable for near-field sound reinforcement and front-fill systems.
________________________________
Both X15 variations share some key strengths:
Rugged construction: Built with high-quality materials for long-lasting performance and weather resistance.
Two line array options we OWN at have at frost FLORIDA - the smaller one is?
Kiva L-Acoustics Kiva.
- The Kiva is a two-way system, which means that it has two drivers: a woofer and a tweeter. The woofer is a 6.5-inch transducer, and the tweeter is a 1.75-inch diaphragm compression driver. - The speaker has a horizontal coverage of 110 degrees and a vertical coverage of 15 degrees.
- The Kiva is a very versatile speaker system. It can be flown from the ceiling, stacked on the ground, or used as a ground stack.
