- Data sheet
According to the principle of the Ribbon tweeter enjoy fan circles remain very popular. Their heyday had the design in the 80s and 90s years of the last century, as the Hanoverian boxes manufacturer, Quadral drove a test victory with the early generations of volcano and Titan after another.
Connoisseurs appreciate the design because of their low moving mass, providing a wide frequency range combined with strong drives. Strength and constancy of the series were not without problems at the time.
Blown or broken off films are today a topic. The chassis used in the eighth generation is such efficiency that’s must be slowed from the crossover to up to 10 decibels. The driver works as a side effect almost constantly idle.
The bandwidth can be seen even today. Not unlike the Quadral tapes without recognizable resonances marched the Diamond Tweeter B & W effortlessly over the 40-kilohertz threshold. Stereoplay stop here to measure because the used microphones that are not designed.
However, the driver produces such high frequencies only in a narrow angle range close to the main axis perpendicular to the front of the boxes. Already 10 or 30 degrees are reached only values above 10 kilohertz.
In terms of distortion the frenulum is inferior to clear the Diamond Tweeter. Between 3 and 4 kHz, so right in the ear most sensitive area, his distortion several-fold higher.
The volcano leaves a proven cone driver with stiff Alum membrane and particularly strong drive to the middle layers. In the bass, a 12-incher is used, for reasons of space diagonally in the housing is mounted, allowing so a contemporary slim boxes front. A kind of pressure Chamber, which reduces the Watt demand in the energy-draining upper bass is located front of the chassis.
Their feudal bass driver secured the volcano great level reserves. The precious box managed the wild bass and synth-shenanigans of the Swiss group Yello (see booklet CD for the January 2010 issue) very casual and punchy.
The volcano has a penchant for vocal nuances
The rousing drums interjections here but far less Bell-clean than she was with their transparency on the B & W – tinged unrivaled front. In the bass played the Quadral stimulus, the B & W tidier and more accurate.
Also, the volcano at the homogeneity fell behind. She could clearly work out although vocal nuances, but the interplay of the parts was the B & W better. The fan base must not interfere with that. The eighth generation will find satisfied customers with their neutrality and level safety.
