[QUOTE="helotaxi, post: 2802748, member: 550915"] Everything referenced to tuning frequency is going to depend of the sub and the system goals. There is no generic "best" tunig freq. What works really well for one sub might not have an even similar result with a different one. For each sub there is a combination of box volume and tuning freq that will result in the flattest freq response. Tune that sub above that freq and you will get a boost in peak output at and above tuning but the response will roll off more quickly below that freq. Tune lower than optimum and you end up with reduced output and you might get an improvement in low end extension. Go too low and you end up with response very similar to a sealed box. Increase box volume above the optimum and you create a response peak similar to the one created by tuning higher than opt. Go smaller than opt. and you depress the output and decrease the low end response. There are some tricks you can use. High tuning and a big box will be really efficient at one small freq range. High tuning and a small box will give fairly flat response but with limited low end extension. Larger box and lower tuning can milk a little low freq extension out of subs that want a fairly high tuning. [/QUOTE]
