Hi;
I have made several ported speaker systems and am familiar with Thiele's alignment tables. I know the tradeoffs between higher and lower Qts in terms of Box volume and fb vs fs; ie. Qts higher than ~ 0.4 and Vb>Vas but f3<fs while lower Qts is the opposite. Is there anything more to picking a driver Qts to design a ported system than this (for instance transient response) that goes with Qts?
Systems I have made to date have had Qts of 0.38-0.57.
Currently I am looking to make a 2 Way ported system with a 6-6.5" woofer. I was considering Vifa NE180W-8, Dayton RS150 and SEAS H1217 all with Qts in the 0.39-0.47 range but read a review of the Silver Flute W17RC38-4 with a Qts of 0.24. Since it is outside of the range I have used to date I was curious the tradeoffs. $ and box size are not a consideration here, just want to know the technical tradeoffs
Thanks!
