[QUOTE="VWBobby, post: 7215944, member: 624844"] I used to be a "sealed only" type of guy for daily driver/SQ. What I've found is that some subs work better in sealed, and others in ported. Usually the woofers with loose suspension and low FS work better in sealed. A sub with a stiff suspension and a higher FS usually responds better in a vented (ported) box. If you have a sub with a weak suspension or a high sensitivity, I prefer a sealed box. A typical sub used today, seems to respond better to vented unless its a specifically designed for sealed installations. I have run several older sets of subs like SoundStream Pro 12's. When I had these in a ported box (designed for them), I noticed the low end would suffer and they would reach excursion a lot easier. When I used the same box but blocked the ports with plugs, the output was dramatically better and power handling went way up. Same subs, same box, only the porting was blocked. I would definitely agree that for pure SPL/DB output a ported box can definitely put out more DB at its peak. Its hard to tune a ported box to a completely flat response compared to a sealed unless you keep it around 28hz... [/QUOTE]
