Feastrex NF-5 and NF-5ex Drivers at SSI 2011

Amplifikatörler, Amfi Modelleri ve fiyatları, en iyi amfi, high end amfilikatör

We are big fans of single full-range driver loud speakers so we were excited to check out the Feastrex drivers. Michael Tang of Mike Tang Audio is importing the Japanese Feastrex NF-5 and NF-5EX drivers into Canada and had them on display at the show.


The 5″ Feastrex NF-5 ($2000CDN, shown above) uses a large Alnico magnet.  The handmade cones are made from Japanese Washi paper (a higher density fibrous paper) which is impressed in a spiral pattern with embossed ridges.  The drivers surround is made from lamb skin.


The 5″ Feastrex NF-5ex ($3000CDN, shown above) uses the same Washi paper cone and a lambskin surround, but with a motor that uses a field-coil magnet (electromagnet).  The field-coil magnet can be operated between 10 and 17V dc.  Changing the voltage allows you to change the damping of the driver.  Michael uses a 12V car battery for the field-coil magnet.  16 ohms, 95 dB, 35 to 25,000 Hz (+/- 3dB).


A Mastersound Compact 845 SET powered the 5″ Feastrex NF-5 drivers which were housed in a bass reflex enclosure (enclosure plans from Feastrex, shown below), no passive filters were used.  The speakers sounded excellent, wide soundstage and impressive depth.  The single drivers delivered superb clarity with vocals to die for. 
 
Michael indicated that he is working on a transmission line enclosure design for use with the Feastrex NF-5 and NF-5ex drivers which he plans to have ready for the TAVES (Toronto Audio and Video Entertainment Show) this fall.
