pervitizm Posted May 19, 2008 Author Report Share Posted May 19, 2008 How much did you pay for your subs? I emailed rusty but he's prolly bussy finishing lvl 5's.

pervitizm Posted May 19, 2008 Author Report Share Posted May 19, 2008 The airspace for both subs is in the middle, meaning that the air pressure from each sub is cancelling out when it gets to the port. You honestly would have a better, more efficient box setup with ports on opposites sides. That box design alone is probably costing you 5-8db easy. Thanks for the advise. I will try to come up with another design later on tonight.

cichlidfort Posted May 19, 2008 Report Share Posted May 19, 2008 It would be better than your current design. So you're saying the design with the port in the middle is more efficient than my L-shaped design that I have?

pervitizm Posted May 20, 2008 Author Report Share Posted May 20, 2008 So you're saying the design with the port in the middle is more efficient than my L-shaped design that I have? I believe he was talking about my design with the port in the middle between the two subs.

cichlidfort Posted May 20, 2008 Report Share Posted May 20, 2008 My current design is a L-shaped box lol. I think you got confused. Quote 2008 Chevy Impala (undercover cop style) Setup in the makings Link to comment Share on other sites More sharing options...

pervitizm Posted May 21, 2008 Author Report Share Posted May 21, 2008 (edited) Ok here we go. This is my third redention of this box. This time I did dual ports on the side of the box. I had to adjust the depth just a bit from 24 to 25.5 inches. Let me know what you guys think. I've got Monday off and I want to get my build on So my new numbers are 24H x 49W x 25.5D. Top and bottom are double 3/4 MDF while the front, back and sides are single 3/4 MDF. The ports are 2.5W x24D x 10H.

You honestly would have a better, more efficient box setup with ports on opposites sides. That box design alone is probably costing you 5-8db easy. Is this true? If so is it really 5-8db? 5 to 8 seems awful high to me even if it is inefficient. Quote Rebuild coming soon Link to comment Share on other sites More sharing options...

The airspace shouldn't be shared for optimum efficiency. Everything else I like. Quote Link to comment Share on other sites More sharing options...
