  1. I have two Fi 12" old x series woofers the ones sold on the black fiday special. My question is, what is the recomended enclosure volume per speaker for a ported box? I have had them in a sealed 1 cubic foot per sub box since I bought them on black friday. Which has been ok for the time being, but I have moved to a hotter climate, and need a ported box to help cool the woofers as well as get the most spl out of the woofers.

    I got new 2 Fi 18's Q series unloaded, no options on them at all. whats the most amount of RMS power I can put on each one???? Im getting the Audiopipe 3000d amp and wiring them at 2 ohms and that would put 1500 rms on them.

    Well,I just ordered a Q15 dual 1 ohm sub for my car. I had a 12w6v2 in a jl spec sealed box but after hearing the Q10 in a sealed boxed that I bought for my wife's car (hers goes lower and sounds better than my 12" ,just not as loud)I decided to go Fi also. I have a 06 Jetta and I wanted to run a sealed enclosure.I have lots of trunk space. I know that the spec sheet says 2-2.6 ft3 but is there anyone running larger and how does it sound. I want to focus on sq and very deep lows.

    Can someone tell me if this port size is right for what I want. Box size is 12.91 cubes after subs and port displacement. the port size is 23hx7wx14.56d = 32Hz. Is this right? 2-18'' Q's will be used in this box. Looking for it to hit really hard and will this box hit loud and hard? the subs will see about 6.45 cubes each. Is this box good for the Q's to hit really hard in?ready to build today....

    I'm looking at picking up 2 SSD's (15"), the box will be roughly 7 - 7.5 cubes. I would like to find out what the optimal size for the port. Still deciding between slot and aero, might need some suggestions there. Let me know the dimensions of the port you would use for mainly SPL in a 7.5 cube box. Thanks!

    Whats a good port length for the BTL as a daily driver tuned around the recommended 32 hz and 14in^2 per cube? 2000rms power. Enclosure will be glassed into the side of my trunk and I have around 4600in^3 before any displacements to work with. So should be around 2cuft after. Trying to see if I can make a ported enclosure work or not. Thanks!

My box is very small for these subs and I drive a big car (Crown Vic) so I know a new box is a good idea.

    Ok right now I have the Q 15's and I've gotten used to them so I want to upgrade to the BL series. My question is, ok i want the same freqency response as the Q's have cause I like how they perform down low, but I need to know which options in the BL should I go with to have a good daily woofer? I was thinking of going with the cooling, flatwind, daily, and universal options because I am not looking to do any competing just some really bad street beating. But Im a little skeptical about the cooling option because it says that there is less metal in the motor thus making it a little weaker? So should I just go with p/chamfer, flatwind, daily, and universal because I dont w…
