TANNOY HPD385 (15'')

(Master M)

 

This is the sound of the Tannoys hooked up to the Siemox amplifier, as recorded with a Neumann stereo studio microphone positioned about 2 meters away from my hi-fi system (set-up: Tannoy HPD385's + Siemox amplifier + Uskok preamplifier + Tascam CD-701 + own DIY interconnects). No filters or effects have been applied. The music is from the CD album "Kastav Blues" by Kastav Blues Sextet (Track 1: Crekvina True Story; mp3, 01:11).
