Audio SPK Thursday, August 21, 2003 TANN SYSTEM 10 DMT Retail BEST $1100 Retail BETTER $950 Retail FAIR-Good $800 DIFFERENTIAL MATERIAL TECHNOLOGY A separate research project had shown amazing results in Differential Material Technology, the science of combining different materials to achieve the required acoustic properties at strategic places in a speaker design.DMT coupled with the new 2025 design put Tannoy firmly on the worldwide map for the Dual Concentric system performing in small footprint domestic cabinet systems. At last the population could listen to recorded material and be assured that they would hear everything that the artist intended. WAVEGUIDE THEORY The Waveguide theory and research started in 1989 for the 2025 was developed in an increasingly sophisticated way using Computer Aided Design and draughting techniques coupled with mathematical modeling of Waveguide principles. Much progress was made during 1989 and 1990 resulting in a very special and totally different approach to the HF section of the Dual Concentric. The 2025 Dual Concentric provided the clues to Tannoy's direction but when the new 12" and 15" Dual Concentric drive units appeared in the Monitor Series System 12 and System 15, people realized that Dual Concentric design would never be a traditional approach again. A new range of professional monitoring systems was introduced in 1990 based on Waveguide principles: System 215 using 3833GG 15" Waveguide Dual Concentric with separate 3834 15" bass (Soffit mount monitor). System 15 using 3833GG 15" Waveguide Dual Concentric (mid field monitor). System 12 using 3133GG 12" Waveguide Dual Concentric (mid field monitor). System 10 using 2525GGG 10" Waveguide Dual Concentric (near field monitor). System 8 using 2025GGG 8" Waveguide Dual Concentric (desktop near field monitor). System 2 using 0259 tweeter and a 1668GG bass/mid 2 way discrete system (desktop near field monitor). All the system series cabinets had a revolutionary design appearance and had all the latest thinking in DMT cabinet design. <P><a href=http://members.aol.com/KDresch/audio.net.html>audio.net</a>, Used Audio Shop<P>Brands: Marantz, Pioneer, Kenwood, Advent, Apt, JBL, Technics, Magnepan, Harman Kardon, AR and many others.<P>100% Customer Satisfaction Guaranteed since 1995.
