So I have been in desire of adding more midbass to my set up. Currently I am using the Sundown CS6.5 set up from only. I feel that i am going to damage the 6.5 that came with this set if I do not pursue an alternative to help cover this midbass I am desireing. I will be sealing up a fiberglass enclosure on my doors. I have been looking at a a couple set ups and was hoping for some advise. I am looking for a midbass driver that will run around 50hz and up not sure where my upper cut off will end at this point. I have been looking at three speaker on is called a subwoofer and the others are called midbass drivers. well here is what I have looked at: 1.Sundown SD8 this will run sealed on my door. If I choose this route I was planning on using two of these CS6.5 as well with this. 2.Dayton audio RS180, with the RS100, and a tweeter as well 3.TB w6, 6.5 midbass driver, with a 3 or 4 inch allrange as well and tweeter Both of these options I am looking at going with a 3- 4" allrange driver to cover the Mid-High end and adding a tweeter as well. I guess my main question is am I going to get the midbass out of the SD8 that I am looking for or would it be a waste of a speaker for this situation. I had odered these and will have to see If I can cancel if it is thought that I should change my direction of focus. I am incredibly new to this active type set up I am looking at going with. So the exact interpitaitons of how these set ups will work has just been choosen through reading on this site.
