How would a sub sound if it had a Qtc of 1.01 in a sealed box?

"higher" "tighter" "snappier" but less low end output and more of a peak. The smaller the sealed enclosure, the higher it likes to play but the larger the peak. The larger the sealed enclosure, the lower and flatter the responce. Larger also means much more efficient, less power required to get the same excursion (output). IMHO, a large box means more efficiency, not a loss in power handling.

How bout the same box that gives 1.01 Qtc but it has a low xmax such as 11mm one way? Is it going to produce much bass if pushed with roughly what the sub can handle?

What sub are you referring to?

Audiobahn AW151T (flame excursion)
The Soundsplinter 15" Rl-s is even better than the audiobahn in about 8ft3 but it cost 5 times as much and needs more power.

Thread moved to the DIY Subwoofers forum.

They say a Q of .7 is the best for music and for HT a Q of .5 gives more low end. I imagine a Q of 1 would sound punchy in the mid range frequencies.

what if the sub was crossed over at 60hz though? I am going to make the enclosures and tinker with things.

What is it your looking for in this sub?
