Single Sealed
I want more bass would a ported and sealed box sound good together?
I have a pair of Infinity Reference 1252w 12" speakers in a ported box hooked up to a infinity 611a mono block amp (657wRMS) and everyone tells me how great they sound and they do sound great but, I noticed that the hit very well on some notes and others not so much, the ones that don't hit as hard hit well in sealed enclosures. so I wanted to add 2 more 12" in single sealed boxes in the sides of my trunk maybe even the same speakers and amp. Would this sound weird or interfere with my ported set up or will it hit hard on every note like I want? Or should I get a bigger amp? The port is on the side of the box heres a pic. http://i48.photobucket.com/albums/f236/StackinMoney/Car%20audio/skeet8.jpg
Like said above, do not try this. It will not give you the results you desire.
It sounds like your Ported Enclosure is "peaky". By that I mean that the enclosure design makes the subs sound better at some frequencies then others, like you described. This is the result typically of a tuning frequency that is too high. This means you will have Great Bass in a limited frequency band and not so good at other frequencies.
The way you can fix this is to get a new enclosure. You could either go with a Sealed Enclosure or a ported enclosure that is tuned lower/designed better. That should fix your problem and give you even bass at all frequencies.
You could also check your amp settings and make sure you don't have your subsonic filter set too high or your high pass filter set too low.
Good Luck!!!
