Reproduce the Live Sound with Wooden Horn
Compression drivers can generate more energy than dome tweeters and are considered the signature of classic horn speakers. Classical 151 belongs to the flagship line from LALS. It features a computer-calculated 62cm horizontal wooden horn with a 100mm diaphragm titanium compression driver and a fast 15-inch paper cone woofer.
The titanium tweeter utilizes an accurate phase design along with powerful magnetism and an advanced chamber. The diaphragm upgrades from 50mm to 100mm can reproduce an extensive frequency range from 300hz to 20khz. This allows it to deliver crystal clear treble while producing strong, thick, and articulate midrange. The 15-inch paper cone woofers with coated fabric surrounds are made of paper and glass fiber composite. They have a 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 650Hz. Classical 151 can deliver a huge sense of sound stage. The sound is open and warm with a lively presentation. Classical 151 can easily generate a room-filling sound when pairing with 7W tube amps thanks to the high-efficiency design at 98dB sensitivity. High power amps can also drive it to obtain stronger dynamics and more authoritative sound.
With Classical 151, LALS offers sound signatures similar to Daniel Hertz and TAD.The sound dispersion and directivity are designed with precise calculation, and ideal frequency response is achieved—a true audio masterpiece.
Treble attenuator for easy tuning in different spaces
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 sounds 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 151. This way, one can easily adjust for optimal performances simply by turning the knob.
Birch plywood enclosure with high-quality finishing
The nice wooden enclosure of Classical 151 ishandmade in Taiwan with the highest standard. Russian birch plywood that is stronger and denser than ordinaryMedium-density fiberboard (MDF) is used to gain lower resonances for better acoustic performance. The high-quality wooden veneer finishing of Classical 151 makes it aesthetically appealing and is suitable for various spaces.
