ported box volume question

Yeah, unfortuanately for me I have no one within 200 miles that sells them so I can't hear them.  I thought I'd use the 21L @33hz because if you look at the top of the page I linked earlier it says "our favorite" for that configuration.  Again though, thats for in home environment.  I'm sure sealed will be good.  That 10L sealed I think is what DYohn used when he listened to them.  He said his kicks were .3 ft3 if I'm not mistaken, and he liked them from what I gathered."I'm Rick James bi***, enjoy yo' self Ah Ah Ah"

Look again at the graph for 21L, 33Hz.  You see that nasty port resonance?  At 300 Hz that's within the vital range of that driver, and it's a 10 db jump.  I would avoid that.Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

Yeah, I'm going to used the sealed for the car it's going to make my life easier.  I'd like to get these for the house though.  I'd also like the 4way for center channel  So many projects, so little time (and money!)"I'm Rick James bi***, enjoy yo' self Ah Ah Ah"

Stevdart, I hate to bug after all you've already done but check these out.  They seem to be real close (I think) to the extremis in the 10L sealed enclosure and much cheaper.  Am I right, or did I overlook something like last time?"I'm Rick James bi***, enjoy yo' self Ah Ah Ah"

A little bit of a difference in power handling, doncha think?  This one should go vented or IB, it looks like. Fs / Qes = 66.7 EBP  Same as the Extremis in this category, IIRC, but a huge difference in Fs and not capable of the power handling (isn't the Extremis capable of 100 watts?).  I would use the vented enclosure for efficiency with this one.  Otherwise I didn't do a spec comparison because my bet is that they are not in the same boat except maybe for the XBL^2 technology.  Email Steven Kephart about this.Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.
