What would be the setup on my head unit for the sub crossover and for the box, would it be a perfect cube or?

Thanks for all you tips, greatly appreciated

 

yup, Creative Sound Solutions in Abbotsford.

a new and improved SDX15 is coming soon, no idea when though.

 

Just tossing the sub in a random ported enclosure is not a smart idea. It's basically the equivalent to walking into a bar, closing your eyes, spinning around a few times, walking forward until you run into a girl, and then marrying her hoping you didn't pick the crack that you saw in the corner.

Check the size of you sealed enclosure you've got in in now and see how it compares to the manufacturers recommended one. Is there any polyfill in the box?

 

preferably not a cube, ideal is a box with non parallel sides to prevent standing waves from causing resonance. A wedge works well...add about 1/2 pound of polyfill per cubic foot for added dampening, and make sure the box is well built usung 3/4" mdf or similar wood and well braced inside...again to avoid resonance that would colour the sound. Not familiar with your head unit's crossover, but it should be more versatile (adjustable) than the amp's..so i'd use that one. If it has settings at 100 hz and lower, i'd start by setting it at 100hz low pass or close to that...set the slope as high as available (may have 6,12,18,24db/oct), and then adjust from there until you like what you hear.

 

I just found this settings in the PDF



I'm gonna try this.

 

Also.. NO BASS BOOST... turn that to zero.. most amps are centered at 45hz and will cause that "boomy" ness you're experiencing.

 

you could also try putting in some sort of filler IE styrofoam blocks into your box (temporarily) to see if you like the sound of a smaller box with them subs

 

He thinks it's too boomy so he should put it in a smaller box?

 

try a smaller box??
