Any opinions on loaded Fi Q 12's? Always wanted to run the Q ever since I bought my SSD.

Thanks for the replys guys. Leaning towards the X's so I can keep everything brand matching. Currently upgrading alternator so ill have to wait for the subs till funds are available.

Thinking of a pair of x 12's by sundown or a pair of lvl 3 12's by dc. What would you consider a better woofer for musical lows.

Did I give them enough port area? Well all I can do at this point is play around with box position and like you said throw some 2x4's in there to lower the enclosure volume some. Doing this may help but I think i'm chasing my own tail here being what you said about cone area. After gaining a little knowledge i'm sure I want to go bigger subs. I like the simplicity of single 15"s so i'm leaning in that direction. I'm really thinking about a DC Audio XL 15", should be close to the same size box.

First off thanks for the detailed response and I would like to clarify that they sound good just lack of output compared to my old 15" ssd. The box is double baffled so that would take up a little bit more room but not quite enough to bring it down to 2.5 cubes. How does lowering the enclosure volume affect output? I can't say for sure about the box being leaky. It is my first box that I built and my cuts weren't perfect but i used lots of caulk to make sure it was sealed but it could be leaking. It has good sound and I can't feel or hear any leaks coming from exterior of box so possible leaky port on inside but I want to doubt that. Back to air movement, air moves like mad crazy inside the port but not so much out of the port. Do I have enough port area? Makes sense that the 15 was louder because of more air movement from more cone area. Wish I knew that before getting the 10's, I foresee a 15 in the very near future for me.

I have two sundown audio sa-10s that i'm not to happy with. They're not getting very loud at all off a saz2500d and i think my box is to blame. I designed and built the enclosure myself, its suppose to be 2.5cubes after displacements tuned to 32hz but not sure how well that worked out. Im at the point where i'm considering selling the 10's and upgrading to 12's or a single 15 cause i'm frustrated with how they sound. I can try a new box but would hate to put the time and money into it if thats not the problem. Current box dimensions are 30x20x14 exterior and the port is 3x12.5x31. I would greatly appreciate some help on my situation, thanks in advance. My old system was a 15" Fi SSD in 4 cubes @ 32hz off a memphis mc1000d and it was noticeably louder.

I got 2 sundown sa-10s that im not satisfied with, looking to upgrade to a single zv415. Will 4 cubes be big enough for this sub on a saz2500d?
