Anyone have 26-28hz songs?

Good stuff. I need to seal up my door panels bad and deaden them, I get some nasty rattling. Get that done and then make a new enclosure for my 18 (4th order bandpass tuned nice and low) and I will be golden //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Yeah I hate having all the rattle I need to deaden the hell out of my trunk and back deck. That 4th order should be real nice they always have great response curves.

Yeah I hope my peak drops a little bit (from 40 down to 37-38 would be nice). I really don't listen to anything above 50 and I roll off pretty fast at 30hz so I figured a bandpass is probably the way to go. Unfortunately I don't have a way of modeling it up though because my 18 is a custom and I have no specs for it //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

what is your cabin gain and box tuning mine is 30hz tuning and its peak range is around tuning frequency and then another peak in the upper 30's for a few notes.

I have heavy cabin gain at around 49-50. My first box was actually tuned to 27hz and then I knocked out one of the ports and brought the tuning up to 33hz. My peak was still 40hz for both tunings

I bet if you raised the port size the peak would lower I would hate a 40hz peak I rarely listen to music above 40hz. The 4th order should hopefully lower your peak to at least the mid 30's but I would try and see if you can get a peak around 30hz I really like how it sounds and when it is loud in the low 30's upper 20's it is just awesome.
