I was wondering if anyone out there has tried building a HST-15 4th order box. If so what ratio and tuning did you use? I currently have it in a 2.5 cuft ported box tuned to 25 hz. It sounds great. I was just curious about possibly trying a 4th order build.

I have sent Nick an email asking for his recommendations. I am just wondering if anyone has tried it yet and what their results were.

I dont know how much space you have but have a feeling it will be large. I have seen his other 4th order recommendations and they are usually 2:1 and sometimes 3:1. I have used 4th orders before, but always ask what are you trying to gain or change by using one?

I have 25" deep X 16" wide X what's needed high. My current box is 25" X 16" X 31". I am just wondering if I can gain a few more dBs. I do like the way my current box sounds. I am just always wondered about 4th orders. If I build one and it doesn't blow me away with the difference I can always go back to my current box. Also from my guess of needing one cube sealed, a 2:1 or 3:1 ratio will actually be smaller than my current box by 4-5 inches of height. Because my current box is tuned to 25 Hz my port is VERY long and makes the box quite large.
