q factor?

Q(tc) = 1.0 This frequency response corresponds to the smallest box of interest.
It has a slightly peaked response.
Q(tc) = 0.707 This is a Butterworth alignment which has the flattest possible frequency response.

Iam not sure what all of that means, learning as I go

No I think lower Q = more compliance.. Q actually describes 'stiffness' which is inverse of compliance

I had a tempest in a small box and it sounded flabby. After investigating, the problem was cause by the small box. I would have thought different.
Still dont know for sure.

It's hard to relate the Q-factor of a woofer system to it's dynamic properties..
A 15 in a huge box with a Q of 0.65 MAY not sound as tight and snappy as an 8 in a small box with a Q of 1.0 or higher.
I usually suggest something around 0.80-0.85 for most people, unless they need to handle a lot of power, then I'll shrink the box for a Q of 0.95 to 1.0.
For me, I'd choose a driver that sounded good, then drop aim for 0.707 or so.. But I am into low, over loud...
Most people attribut loud boomy bass to good bass, so they want a small box.

i built a box .66 ft3. 12x12x12 3/4 mdf. I amlooking for sq and space is an issue that is why i chose sealed. As far as the question goes I see it is not an easy answer but it seems to me most are saying higher q is better for sq.
