Engineering and design at the service of your senses, so you can perceive sounds with enhanced intensity and power. Vertrag™ is a new way of listening to music. Its technological and acoustic innovations enable you to perceive every detail of your favorite music.SOUND QUALITY:Vertrag delivers a high quality sound, with a high response and performance. It has the ability to harmonize perfectly the extreme treble and bass frequencies, allowing a pure playback of music. It´s essential for those who seek high performance equipments in the home audio system range.DESIGN:In Vertrag we can appreciate a geometric design where the fine details in the lateral angles add a fresh and dynamic note. Medium sized, exactly 161 x 190 x 240 mm, it has the ability to provide class and elegance to every room of your house.UnltdSOUND:At T&V we develop our products to satisfy our users needs. All of our products are designed and produced with the best acoustic components. We are known for providing high quality and powerful speakers, and our developments stand out for having a minimum distortion when played at high volumeHOWL BASS:Howl Bass technology extends low frequencies delivering a more natural, deep bass and surrounding sound. This development makes it possible to reach well-defined bass in a compact size, offering a powerful sound in your living room. You can experience the sound like in a real theater.HDAA (HIGH DENSITY ACOUSTIC ABSORBER):It is a natural polymer of high density that when combined, generates a more rigid and dense material than the MDF manufactured today. These properties prevent vibration and leakage of sound, enabling a more accurate, efficient and sustainable performance.ANTIMAGNETIC SHIELD:It is a technology that allows you to isolate the sound of external interference, allowing a pure and crystal clear sound flow without noises irruptions.MESH:This protective cloth works as a shield,protecting the drivers from any damage and from all kinds of harmful agents. This helps to take care of both sound quality and equipment performance.BASS REFLEX:The Bass Reflex Sound enhances the sound expelled through the rear of the diaphragm. This way the resonance system increases the bass response of the controller and optimizes the efficiency and performance of low frequencies.TWEETER:The 0.5 inches tweeter is made entirely of polyethylene micro sheets, which provide precision and detail on treble.WOOFER:Each speaker has a 4-inch woofer made of cane lignin fiber. This natural polymer is ultra-durable and lightweight, optimizing the driver´s performance. The upper suspension ring is made of rubber, allowing greater displacement sensitivity.DUAL RCA STEREO INPUT:Each playback device needs different types of amplification, according to the intensity of its output. For devices with weaker signals (mp3, smartphones, tablets) input one is used to maximize its output. Input two is used for devices with strong signals (TV, DVD, semiprofessional sound plates). The speaker adapts to the different inputs for better performance while minimizing distortion.CONTROLS:Ergonomic controls are made of cutting edge materials, which allow optimizing the selection range by regulating in a precise and detailed way the volume, bass and trebles. Perfect to control the sound of your movies, videos and favorite music.POWER SWITCH ON/OFF:Saving energy is part of the preservation of the environment, one of our main goals. That´s why our equipments have an on/off switch that completely interrupts power to the equipment. This allows energy savings when the speaker is not being used.Thonet and Vander Vertrag Specifications:
