[QUOTE="NSTALN, post: 8611883, member: 588169"] I'm planning on building a ported enclosure for a singe Audiomobile MASS 12....the box will be 2 cubes tuned around 26hz. The subs xmax is 20mm and I'll only be feeding it 600rms. The plan is to use a 5inch PVC pipe for the port. The port will be glassed into the sidewalls of the enclosure and will be rounded (3/4 round-over bit) at both ends. The area for a 5inch PVC pipe is 19.63 inches/sq...general rule is 8-12 per cube...this puts me at just about the middle of that range. WINISD model shows max port velocity is 22m/s @ 23hz. I know some of you folks are quite good with the ported designs...do you think that will be sufficient? Thoughts/suggestions? [/QUOTE]
