I think we are all getting a little off topic with the ported vs
PR vs sealed debate. Remember that the OP already has the driver and is considering a pre-made box. To summarize:
1 - Ported. Properly designed you'll get up to 6db of addotional output near the tuning frequency which would result in deeper response, less power needed and lower distortion, though if tuned much above 17hz group delay can enter the audible realm. The box will be more challenging to design and build but there are plenty of people on this site to help with this and a notch filter may be needed.
2. Passive Radiator - Everything above applies though you won't have to worry about a notch filter, port compression or chuffing. You will need to purchase a radiator or two to get the best performance.
3. Sealed. The simplest design. All of the above issues become a moot point at the expense of 6 db of output down low. According to a model earlier this would still result in 114db at 20hz anachoic and last I checked this is pretty awesome.
So there you have it. If you want tremendous output and don't mind putting in a little extra work, ported or
PR are good solutions. If this is your first build and want a simple design, go sealed.
tpaxadpom - I looked at the pro wedge you were considering. The box looks awefully small to me for a home theater application. With smaller volume you increase the system Q value which leads to extremely high trasient response at the expense of extension and efficiency. I think you'd find it to be a bit boomy. Anyone have acces to WinISD to run some quick numbers for a sealed enclosure for .707? If you don't mind building your own the MDF can be had for less than the cost of the Pro Wedge and would yield better results IMHO. Let us know what you're thinking.
