I just got a id12 image dynamics dual 4 ohm and I was wondering what box type and size you recommend for best sq ....I know youve been around these subs so I trust your direction
Either sealed, around 1.3 cu ft net, or ported 2 cu ft net tuned to 30hz. Honestly, they work very well in both enclosures and it's more about preference. I prefer low tuned ported boxes with them, but opinions will vary.
thanks Jonathan how would the lowest bass extention to the 20 hz range be in sealed?.. or should I aim for ported to control the subwoofers extension in that frequency range and the surrounding frequencies im lookin for controlled bass all the way down and ill be running 140 rms to the sub and id like to keep it that low in power but if i have too ill put a larger amplifier I have on it providing 200 rms
