After reading about Harley haulers ib I decided to try out a pair of the kicker comp 15s. After modeling in winisd it looks ok as far as I can tell I. The 87 cuft cabinet. I just can't figure out if I need to worry about a high pass filter. I will be using a inuke 1000 to power the subs. The amp may be a little overkill but I figure if I don't push it I should be ok. I tried to model them as a ported sub but I couldn't figure that out I don't know what I should tune it to. Any input would be appreciated
Yes, much more output in vented. Here's a single Comp vented compared to a single Comp In an IB.
Each sub will need 10 cu.ft. tuned to 22 hz with two 4" round ports. Power would be 250 watts with a subsonic filter at 18 hz for each sub.
