I have obtained the
Dayton RSS390HF-4 15", and require advice on the design.
After reading Ray Alden's speaker building book and having browsed through 100's of threads. The recommended ported box size is around 9 cu ft, which is not reasonable by any means. Going ported is completely ruled out. Same with other designs like isobaric. Which leaves me with a sealed design. For this driver with sealed, I understand I might have to compromise on the low end or something else to a certain degree. After much contemplation, the only design that I can do, is sealed. Hence this thread.
So, I have made three decisions to begin with.
- Driver is RSS390HF 15" (I already have it).
- Design is Sealed box.
- Amp is external - XLS 1500 or XLS 2002 (I have both). I also have a MiniDSP.
Next up is box size. Which is where I require advice.
Reading through numerous threads across different forums, I find the sealed box size for this driver vary widely from 2.5 to 6 cu ft.
So what is the best sealed box size for this driver and why?
