[QUOTE="SofireGuy, post: 4190224, member: 566724"] Ok.. So I have 2 Rockford Fosgate Punch Series 3 Subs. Info: * Sensitivity: 85 dB * RMS Power Range : 100-400 Watts * Peak Power Handling: 800 Watts * Impedance: Dual 4 Ohm * Low Frequency response: 20 Hz * High Frequency Response: 200 Hz * Diameter: 10 Inch So I wanna see what these babies can do. I had them in about a .50 or .65 Cu Ft. Sealed Box Before. They didn't seem to do to well especially with the lows. So what I need is a program or something to help me design a ported box for 1 cu. ft. and instead of tuning it to 35Hz I wanna try to get lower and tune it to 28Hz. Anyone know of any programs that can help me with this that are free or inexpensive, say no more than $20-30. [/QUOTE]
