The company Mark&Daniel Audio Labs has introduced a series of modular acoustics Ultrumax. These systems are based on the AMT (Air Motion Transformer) tape driver from Mark&Daniel, which provided a record low frequency limit of 200 Hz for this technology.
In fact, AMT drivers are traditionally used as tweeters. But Mark&Daniel has consistently expanded their range into the low-frequency domain. Their 1st-and 2nd-generation Dreams AMT drivers already demonstrated wideband frequency ranges of 800 Hz-20 kHz. According to the manufacturer, the Ultrumax series was inspired by the spirit of Qin, the first great Creator of the Chinese dynasty (221 BC).
Ultrumax acoustics are based on the AMT DM8a wideband driver with a corrugated membrane. These are modular systems that can include one (Ultrumax-1U model) or two (Ultrumax-2U) such drivers. Moreover, the version with two drivers can be supplemented with an Omni-directional super-tweeter (model 2U-ST), operating in the range from 7 kHz and higher.
These ultrumax-Stand tube-mounted systems can be supplemented with an Ultrumax-Sub-Ia subwoofer of a fairly traditional design with a down-pointing 10-inch WOOFER. Another option is a low — frequency module-stand Ultrumax-Sub-IIa based on an 8-inch driver.
Both low-frequency units have integrated amplifiers. One, class D and 150 watts of power, serves a low-frequency speaker — and another pair is designed to work with AMT drivers. Ultrumax acoustic cabinets, which are already traditional for Mark&Daniel, are made of very dense and heavy composite marble CAM of our own production.
As for prices, in the US, the Ultrumax-1U will cost $1,250, and the Ultrumax-Sub-IIa will cost $3,000 per pair.
