[QUOTE="sundownz, post: 6736820, member: 549523"] First we made a REALLY small ported box... but the tuning was too high and extended the port messed up the phase relationship... [IMG]http://www.sundownaudio.com/misc/96_Jeep/SIBM12/TWOBM/CIMG3488.JPG[/IMG] [IMG]http://www.sundownaudio.com/misc/96_Jeep/SIBM12/TWOBM/CIMG3490.JPG[/IMG] [IMG]http://www.sundownaudio.com/misc/96_Jeep/SIBM12/TWOBM/CIMG3491.JPG[/IMG] Not much better than the single woofer at it's best so we quit on this box. So... we modified one of my dual 8" woofer boxes to hold two 12s -- about 75% larger than the first : [IMG]http://www.sundownaudio.com/misc/96_Jeep/SIBM12/TWOBM/CIMG3497.JPG[/IMG] [IMG]http://www.sundownaudio.com/misc/96_Jeep/SIBM12/TWOBM/CIMG3498.JPG[/IMG] I forgot to take pictures yesterday... the port did have a flare on the end. MUCH shorter port. This is what we got : [IMG]http://www.sundownaudio.com/misc/96_Jeep/SIBM12/TWOBM/CIMG3496.JPG[/IMG] [/QUOTE]
