[QUOTE="americannight, post: 8039723, member: 624648"] Yep, the added fiberfill gave me the effect I was looking for. I put about another .50 to .75 lb of fiberfill in each chamber. That's basically completely stuffed. I'm sure I am giving up some SPL by doing this but the sound is a lot less peaky. This week I'm going to finish doing the vinyl on the second amp rack panel and then Saturday will be the big day to install all of this in the trunk. The sub enclosure will be the very last thing I will vinyl because I do want to hear how it sounds in the vehicle with the Zed amp on it. I'll play around with stuffing the ports to simulate a sealed box. If sealed sounds better then I will probably end up removing the ports and sealing it before doing the vinyl on the sub box. At this point I'm liking the ported, though. I believe there is about 1.55 cubic feet per chamber before stuffing. I tuned the box to 32Hz with the precision ports. I estimate by stuffing the box full of fiberfill it is effectively about 1.80 cubic feet per chamber so the effective tuning is now lower than the original 32Hz which is fine by me since that seems to provide better sound quality. But gloves are off once this is in the vehicle and I get cabin gain effects, etc. We'll see how that all pans out. The ported/sealed debate is not settled yet in my opinion. [/QUOTE]
