Opals
System overview

Opals are fully 4-way active integrated monitor systems that can be applied to a range of applications including domestic, studio monitoring, commercial and PA. Designed to give the highest fidelity performance technically achievable, the Opal systems are also crafted to suite most environments. Custom Opal systems can be consigned for more specific applications and environments.

All Opal systems are supplied with in-built solid-state amplification and internal 4-way active crossovers. For those wanting a sweeter, warmer experience, fully 4-way active valve towers can be added.

The Opal system structure is based on a 3-way center speaker system consisting of a 2in compression driver for upper voice, ribbon or compression tweeters for harmonics and 12in flared cabinet or front loaded 15in for lower voice. Completed as a 4-way with 2 x 15in, 18in or 21in bass speakers.

Lenard 4-way active integrated sound systems create a 3D, virtual reality, fully dynamic experience. The effect is breathtaking. Hearing complete clarity and detailed separation, as though the musicians are actually present.

The Classic Black Opal system cabinets are crafted from the finest Australian hardwoods. The exponential horns are CNC machined from solid 100 year old redgum. This system is equipped with two valve amplifier towers.

The Classic Black Opal system can be replicated as a Custom Opal system.

The way we hear the natural world

4-way active is the application of dividing the music spectrum into 4 registers: bass; lower voice; upper voice and harmonics. Fully 4-way active is when the music signal is divided by an electronic cross-over prior to it being sent to the dedicated amplifiers and speakers. This allows for an experience as we hear sound in the natural world.

4-way active achieves every criteria without compromise.


Valve Amplifiers
Overview

Each amplifier cabinet consists of five 100 Watt Ultra-linear valve amplifiers. The amplifiers are mounted vertically. There is a separate amplifier for each speaker. The 2 two lower amplifiers drive the bass speakers and top amplifiers drive the higher frequency speakers; the order is logical to follow.

The amplifiers for the cone speakers (bass and lower voice) are in class AB which enables 100 Watts of power to be achieved. However the amplifiers for the upper voice 2in compression driver and tweeter are in class A which limits power to 40 Watts.

The efficiency of the compression driver and tweeter is approx 100 times greater than the lower frequency cone speakers and only requires 1/100 the power to achieve the same level.

The high frequency drivers are very sensitive to detail and it is essential for the amplifiers to be as close to class A as possible to achieve the lowest distortion figurers.

The 4 four way active crossover is at the top of the cabinet and the controls easily accessible. The crossover frequencies are calibrated to achieve the best performance from the speakers.

The level controls of the crossover are calibrated for free field which means zero room reverberation. The controls can be easily re-adjusted to give the best performance to suit the room environment and music.

The crossover is Linkwitz-Riley 4th order time aligned
