[QUOTE="jsloan10, post: 976350, member: 560397"] Seriously, if you put those in a ported box they will sound completely different, they will kick all out *** actually. In this sealed box graph the red curve represents you're response curve, notice how it drops dramatically from 100hz to a total of -15db at 20hz, even with the average +12db cabin gain they will still play below the 0db baseline and basically get drowned out by the mids and tweets, good for an RTA readout but crap for listening. [IMG]http://img295.imageshack.us/img295/3476/rli10sealed6qy.gif[/IMG] In this ported box graph you see a completely different beast, the sub plays 100hz to 26hz within a 3DB variation(green line) with a plus 1DB at 26HZ. This enclosure starts where the sealed box maxes out, factor in a 12DB cabin gain and you have a nice slope starting at 26HZ an sloping down to 100HZ, basically the exact opposite of the sealed graph. Green line 1.25 cu ft net Tuned to 26 Hz 20 sq. in. of Vent Area [IMG]http://img295.imageshack.us/img295/3083/rli10vented6hg.gif[/IMG] This sub is worth the effort of getting a new box, seriously they will kick ***.
