Playa Named Joe Posted December 1, 2009 Report Share Posted December 1, 2009 So I'm looking to upgrade, and don't want to redo my box. Would a 15" Level 4 perform well in a 4^3 ft tuned 35hz box? I have seen that they like to be tuned lowwer. Quote 1994 Pontiac Grand Prix build Link to comment Share on other sites More sharing options...
JPagan Posted December 1, 2009 Report Share Posted December 1, 2009 go with 3 cubes tuned at 35hz Quote Link to comment Share on other sites More sharing options...
Playa Named Joe Posted December 1, 2009 Author Report Share Posted December 1, 2009 (edited) Well... I'm not doing another box, I need a 15" sub that'll take 1300rms in 4^3 ft at 35 hz and sound good and loud as hell. I was thinking about one the Z15s from Sundown, but site says like 3.25^3 ft max... $200 shipped is a kick ass deal Edited December 1, 2009 by Playa Named Joe Quote 1994 Pontiac Grand Prix build Link to comment Share on other sites More sharing options...

younggun69 Posted December 1, 2009 Report Share Posted December 1, 2009 (edited) I had one in a hybrid t-line that performed amazingly. I think it was like 11 cubes? Tuned to like 32ishhz.

Playa Named Joe Posted December 6, 2009 Author Report Share Posted December 6, 2009 So this is probly not a good choice for my box then? Quote 1994 Pontiac Grand Prix build Link to comment Share on other sites More sharing options...
Ben Building Posted December 6, 2009 Report Share Posted December 6, 2009 Why not change the tuning on your current box? What kind of port do you have, round or square? To lower the tuning of an enclosure of a given volume, you would need to add length (air mass) to the port. The design and shape of your current port will determine whether this is even practical, but extending the port is a viable option if you don't want to rebuild the whole box right now.

I'm not sure if I could extend the port, it would be a pain. The top is glues and screwed down really good. How could I go about changing the tuning? Would lowering the tuning like 5-3 hz really make a huge diffence, worth the effort? The box is 30 inches deep with the port being 5 inches wide and 17 inches long and 10.5 tall. Box is 30 x 30 x 12 with 3/4 wood. Quote 1994 Pontiac Grand Prix build Link to comment Share on other sites More sharing options...
