what is it? is it better to have a low q or high?
|
Which Q?
|
in the driver paremeters for a sealed enclosure a .66 sizes gives a q factor of 0.707 a 1 ft sixe gives a q factor of 0.589. What is a q factor?
|
the menu:
Qts Qes Qms or Box alignment Q (used for decribing sealed box low frequency characteristics) |
i would think that he is refering to the q of the box

Ok, what you are looking at is a value for comparing the driver's resopnse before rolling off. A value of 0.707 is considered perfectly flat frequency response wise with a 12db/oct low freq. roll off rate. A value of 0.59 is going to have a less pronounced low frequency roll off (it will sound deeper) but will have less midbass punch to it. A value of 1.0 is widely popular in car audio due to it's enherent punch or boost in the midbasss region. This gives a stronger amount of kick on music transients, but less low end extension. |
so a choice between the two if you had it would be the .707? Sorry still trying to understand

There is cabin gain to consider here as well.

What PEI describes is a side effect of box Q, IMO..
The total Q for your woofer system describes the compliance of the driver in the box... A higher Q will have better transient response... (better accuracy, 'tighter' sound) a lower Q will give you a sloppy boomy sound... As PEI mentioned, this is directly related to the frequency response of the box with a given woofer as well... If I were you I'd stick with .707 [img]graemlins/thumb.gif[/img] [ November 22, 2004, 06:36 AM: Message edited by: Haunz ] |
