Compression drivers can generate more energy than dome tweeters and are considered as the signature of classic horn speakers. Classical 12 EX features a computer-calculated 37cm horizontal wooden horn with 50mm diaphragm titanium compression driver and a fast 12 inch paper cone woofer.
The titanium tweeter utilizes accurate phase design along with powerful magnetism and advanced chamber. The diaphragm upgrades from 44mm to 50mm and can reproduce a very wide frequency range from 800hz to 20khz. This allow it to deliver crystal clear treble at the same time produce strong, thick and articulate midrange. The 12 inch paper cone woofers with coated fabric surrounds are made of paper and glass fiber composite. They have shorter stroke than ordinary drivers and can deliver ultra fast transient response while maintaining really high linearity.
The crossover network adopts high quality customized components and sets the crossover frequency at a low 950Hz. Classical 12 EX is able to deliver a huge sense of sound stage. The sound is open and warm with lively presentation. Classical 12 EX can easily generate room-filling sound when pairing with 7W tube amps thanks to the high efficiency design at 96dB sensitivity. It can also be driven by high power amps to obtain stronger dynamics and more authoritative sound.
With Classical 12 EX, LALS offers sound signatures similar to Daniel Hertz and TAD.The sound dispersion and directivity is designed with precise calculation and ideal frequency response is achieved. A true audio masterpiece. Horn speakers are highly efficient. This allows them to achieve lifelike and highly realistic sound effortlessly. In the meantime, the high energy output from the horns can sometimes lead to shouty and harsh sound in some spaces like concrete houses that have room modes emphasizing high frequencies. To better tame the treble under these circumstances, LALS has put the treble attenuators at the back of Classical 12 EX. This way, one can easily adjust for optimal performances simply by turning the knob.
