I have finally completed my Blueprint Sonosub. Next to my SVS 16-46cs+ this thing is a monster. It is built using a 20" diameter sono tube, 6" diameter flared port and 1.5" thick end caps, basically using ThomasW's recommendation on sizing. All in all it went pretty smooth, but there are a few things I would do differently next time (if there is a next time). GET a router bit that is long enough to cut completely through your end caps from one side. My bit was only 1" tall so I had to come from both sides, making sanding the edges smooth a lot of work. Other than that everything was fairly easy.
On first impressions, the Blueprint sub has tons of headroom, hell I knocked a picture off the wall in the scene where the USS Arizona blows up in Pearl Harbor. I calibrated the sub a little HOT to see what it could do. The sub is tuned to 18hz but seems to lack power under 25hz. I will pick up a BFD and EQ it, hoping this will help tame the top end and boost the low end a little.
Bottom line (so far) is the Blueprint sub is louder than 1 SVS 16-46cs+ but Im not sure it would blow away 2 SVS's. As far as pitch, the SVS seams to do a better job at 20hz and below at moderate volumes. I will do a frequency sweep on the new sub and compare the numbers, then update this post.
