Without the help of this forum this sub would have never come into being. You guys are so good and the information received here is phenomenal. That goes for Kyle Richardson from Acoustic Visions as well. Great to work with and helped me tons in getting a sub that was going to fit my needs. Well as the subject states I built a sub that mirrors the "Denali" which is being offered through Acoustic Visions. This sub is a sub that I don't think I will be replacing anytime soon. I started off with a klipsch many moons ago, then got a sv 20-39, then moved onto Dual Triad Silver subs, and now I have settled on something that I think is the ultimate in bass replication. Man does this sub sound awesome during movies, and its presence during music is seamless. Here is a link of some pics I took of the sub: Denali Pics Thanks for all your help through posting in previous threads so that the info is there for people to read and learn. Much appreciated. A lot learned and somethings learned to late. That is in regards to the use of t-nuts, which I will stand on the position of the not recommended. I had one come out of position and I ended up using a lock nut on instead of the t-nut. Live and learn.
