It has a light easy sound, a little warm, not so "shaped" so it will suit the listening tastes of many people. Its cone gives much musical detail and makes a very clear sound. The driver has a medium efficiency of 85.5 dB at 8 Ohms making it easy to use on nearly all small to medium power amplifiers. The driver can easily fit into Bass-reflex and Vented box sizes from 4.4 liters to 10 liters internal volume. Many technical improvements have been made. Improved stiffer frame. New cap design with a new improved fitting method. New Japanese designed coil. New spider for improved bass. The new CHR-70 Gen. 3 is an excellent high-end and multi-purpose driver.

        Brilliant fullrange… I used it instead a Seas driver in LX Mini speakers clone and it performs excellent

        Gut verarbeitetes Breitbandchassis mit Kunststoffkorb. Stabile Anschlüsse, Befestigungsschrauben liegen bei. In meinem Projekt wurden vier gleiche Lautsprecher gebaut. 2 wurden mit dem Markaudio bestückt und zwei mit einem TangBand Breitbänder. Später konnten beide Lautsprecherpaare direkt miteinander verglichen werden. Für den Preis spielt das Markaudio sehr gut und kann für weitere Projekte empfohlen werden.
