Martin Clayton Posted February 8, 2014 Report Share Posted February 8, 2014 Heleeelllpp!!! Im ready to pull my hair out designing this box. I have a max useable space of H 17" W 35" D 15" and im trying to get it to tune to 34hz thats with two alpine SWR-12D4's. If anybody would be kind enough to point me in the correct direction it would be much appreciated I also don't know wether to use a slot or a round port. I think the recommended vented enclosure on the specs is 1.5cuft but could be wrong.

In this range, human hearing is not very sensitive, so sounds in this range tend to be felt more than heard" Link to comment Share on other sites More sharing options...
Joe X Posted February 9, 2014 Report Share Posted February 9, 2014 Yes it can barely be done: But port area is not too great, 4" of free airspace in front of the ports is needed. Everyone has more than 15" deep so I would take some space to do a slot port. Link to comment Share on other sites More sharing options...
Martin Clayton Posted February 9, 2014 Author Report Share Posted February 9, 2014 Thanks for your help joe, so you think a slot L port is not possible?

Joe X Posted February 9, 2014 Report Share Posted February 9, 2014 If the box is 17.5" deep then it can be done. Link to comment Share on other sites More sharing options...
Martin Clayton Posted February 9, 2014 Author Report Share Posted February 9, 2014 What if i went 18 high 16 deep? Or would that not help? I could go 17.5 deep but would have to find another place to mound my amps :S "Sub-bass sounds are those approximately below 60 Hz and extending downward to include the lowest frequency humans can hear, typically 20 Hz.
