I tested Vitavox S1, Altec 288-16K and Philips
5502 (see picture) Frequency range from 250Hz to 5kHz is + - 2db
!!!!!!!!!!!.
That sounds very nice and natural, (specially wooden Instruments on classic) Same Driver on the original 1505 makes a long at resonating tone at 380Hz and +3db.. I am happy with my decision and congratulate you to that fine work." " I measured that the Damping of wood (using Brüel & Kjaer accelerating equipment ) is much better than metal or fiberglas." |
