First off I'm new here to the forum. And I've become interested in making a DIY Sonotube sub. I get the concept of how the sub is built but I have a few questions about a couple of things mainly how to get a correct volume for the tube. I've punched some numbers into a few different programs WinIsd Beta and the Pro Alpha, and Unibox but I'm not really sure what volume of tube I need. I was shooting to find possibly a 24" wide tube to eliminate the height of the tube . The driver I'm interested in using is the DAYTON RSS390HF-4 15" HIGH FIDELITY from PE. The T/S parameters are Specifications: *Power handling: 500 watts RMS/800 watts max *VCdia: 2-1/2" *Le: 1.00 mH *Impedance: 4 ohms *Re: 3.3 ohms *Frequency range: 18 - 800 Hz *Fs: 18 Hz *Magnet weight: 150 oz. *SPL: 90 dB 2.83 V/1m *Vas: 9.55 cu. ft. *Qms: 3.10 *Qes: .49 *Qts: .42 *Xmax: 14mm *Dimensions: A: 15-5/16", B: 14-1/8", C: 6-1/8".
According to WinIsd Beta to tune the box to 17 Hz I need a volume of 18850.2 cubic inches or 308.9 l's with a 6" port 18.5" long
According to WinIsd Alpha to get 17 Hz I need a volume of 648.4 l's with a 6" port and 7.07" long.
I might be punching in some numbers wrong. Thats one of the reasons that I came here because I've been reading a lot of the DIY threads and seen the knowledge that is being shared on the forums and figured this is the place I need to be.
And the second question is what power from an amp should I go for? I was thinking about using a power amp instead of a plate amp. I didn't know if I should match up the power to the RMS value or the Peak Power handling value. I plan on starting the project early summer maybe late spring, right now I am just doing some planning ahead so i know what to expect material wise when I go out and start my project. Thanks in advance for your input and advice
