[ Moderator's note: while this initially appears better
suited for rec.audio.tech, I think that this may be a good
starting point for a discussion of technical figures and
their relationship to quality. -- dsr ]
I have been an analog circuit designer for decades and I have recently
rediscovered my interest in speaker design. I am playing around with
a pair of cheap "full range" coax drivers for the fun of it and as a
way to gain experience in measuring Theile/Small parameters and
playing with enclosure concepts.
The question: I have read that high Qts drivers "will not work" for
bass reflex designs. I measured the small 5.25 inch drivers I am
experimenting with (typically used in car audio) as having a Qts of
1.88. Based on my reading, this is very high (is it even too high a
value to be real i.e. I screwed up the measurement?). I would
appreciate any insight or discussion on why high Qts drivers and bass
reflex don't go together. TIA, Steve
