Hello, I'm trying to build a box for a single RE SE12" I just purchased.
I'm using a Hifonics BXi1606D @ 2 ohms (900-1100 watts rms depending on who you ask)
I was looking at the RE Calculator, but I was reading this thread (http://www.talkaudio.co.uk/vbb/showthread.php?t=245710) and they mentioned their calculator tuning freq is off. I plugged in some of the free box designs found on the sticky here and I found this seemed to be true so I'm going to avoid that calculator.
Now I'm reading for the SE12 they recommend 2.0 CuFt+PD (Port Displacement) tuned to 33hz.
I took at the free sub box designs and I pretty much decided on one of the following designs:
2 CuFt @ 32hz v1
2 CuFt @ 32hz v2
2.15 CuFt @ 32hz
2.35 CuFt @ 33hz
I did some calculations and it seems they already take into account the 0.15 driver displacement of the SE12, so thats good. I couldn't find a 2.0 @ 33hz so the above 4 are the closest. I found a 2.35 @ 33hz, is it worse to have a larger box than what RE recommends?? I'm not really going for SQ or anything just some hard pounding bass. The box is going into a van so size isn't a huge issue.
I do want the option to take it out of the vehicle, so I want to do a CRX style box (I think thats what this is called) where the sub points up and the port points towards the rear of the van. This is so I don't wreck the sub while carrying it around. I found a picture of what I mean. The only problem I have is I don't know if this person did the L shaped port or not. Could the long L shaped port cause a problem mounting the sub like this sound wise? I did choose the 4 above designs based on being able to mount the sub like this size wise.
