[QUOTE="Haunz, post: 8519969, member: 576010"] So far I've looked at 13.5 cubic feet (16.7 Net) ported to 20Hz which gives a 4db bass shelf in winisd with the published specs. I also looked at 11 cubic feet ported about the same frequency tonight. I was hoping after break in response would flatten out, but you can't really know until you get there. I found one reference online stating FS of a new driver was 43Hz along with other varied parameters from the ones published. On the other hand I remember reconing a well used 12" for a guy and noting how loose the suspension was from mine which are still new. I guess all I can do is break on in a bit free air for awhile and measure the parameters myself and make a judgment call on a box, or to just sell them. I've got a Dayton T/S tester but I don't really trust it, and it seems like a piece of crap to be honest. I can measure the traditional way but I'd have to put together a jig and lookup all the calculations so I can do them by hand. [/QUOTE]
