nisam siguran dali je pravi nacin...nekako mi je ostalo u sjecanju da je bilo jos nesto bitno...idem potraziti...ali evo za prvu ruku
Next we need to look at the Qts of the driver which is defined by its moving mass, the springiness of the suspension and the electrical damping from its magnetic system. Again, for a speaker in an enclosure, we would normally select a Q > 0.3 for a closed box speaker and a Q < 0.5 for a reflex design.
For an Open Baffle speaker using a passive crossover we actually require a driver with a high Qts. A Qts > 0.77 will mean that the amplifier will find it easier to drive the speaker as the frequency becomes closer to the system resonance. By careful choice of resonant frequency we can use this to extend the response below the baffle cut off frequency.
