i have plans for a box 1.5cf slot port tuned to 26 hz.if i make the box only 1 cf but dont change the length of the port what will it now be tuned to?

 

Probly change to around 33/34 hz if your volumes are net, but you might be better off sealed if you need to go that small.

What sub do you have?

an ultimate cupric 12" i wanted to do an ABC enclosure but was told that wouldnt work to good.here is a reply i got from another form heres a link


i want more ouput than i can get from a sealed enclosure.since low tuning and small boxes dont work well togther.i was going to do a slot port.
the size of the box is not an issue i just want it to sound good and and have decent spl.

 

ill be using that site as soon as i can figure out what box size and tuning im gonna be using
