[QUOTE="wolfey, post: 76034, member: 544404"] sometimes with ported enclosures you dont get quite the punchiness that you get with a sealed enclosure, and depending on how you port it, it might not get as low either.. however thats not always true. If you've ever heard a ported sub compared to a sealed sub youd notice that ported subs tend to peak at certain frequencies a (i think between 40-60 hz usually) and thats a range which is real common for a bass line.. thus in that range you will get great frequency responce, (and can get much louder than in a sealed enclosure) but at other frequencies above and below that, ported tends to roll off a bit steeper i believe.. This is just what i've inferred, so dont take my word for everything.. i think i'm at least 1/2 accurate about that. Some people tend to like the sound of ported enclosures better than sealed.. It just depends for me. I'd say if you get a big sealed enclosure you will get nice frequency responce and a good amount of spl. That amp might be pushing your subs though.. they are rated at i think 650wrms max but thats in a small enclosure.. Just dont put your gains too high and you should be alright.. I'd recommend 1.5-2.0 sealed per chamber. If you are going to port put them in 4-6cf total and tune at or below 28hz, and make sure to use a subsonic filter to limit excursion below tuning frequency.
