Hi guys,
I have not posted in a long time and wanted to share some of my experiences with you. I try many different pieces of equipment in my theater just for curiosity and trying to get that extra something. Sometimes I succeed and other times I just waste money. I have owned many subs and other pieces of equipment and as I changed things out I have figured some things out. My favorite commercial subs that I have had experience with are Klipsch THX ultra 2 subs with amps and dual SVS 16-46cs+ subs with Samson amps. The bass was great with these subs and the performance was similar in my room. I then tried some pro subs that did not have as flat as a curve but the power from 20-80hz(my crossover) was amazing. I used to hit 115 db's with the other 2 subs from 16-80hz at my listening position and I would hit 110 db's at 15 hz with the pro subs and 125 db's from 20-80hz. Once I felt the 125 db's it was all over for me. So I called SVS wanting to know what would it take to reach these levels with the 16-46cs+ and the cost was too great. My goal was to reach 125 db's from 15-80hz. Ed at SVS pointed me toward DIY and sonosubs for a cheap solution. I ended up building four 6 feet tall and 24 inches round sonosubs using the elemental designs 190v.2 drivers which is 18 inches. I tuned them to 13.4 hz and in my room(a 2300 cubic foot room with great room gain) would extend down to 10 hz and I reached my goal. I called those my silo missles. I kept reading and hearing how great sealed subs sound and how in a sealed room could naturally extend down to 5 hz with good gain which I knew I had(after owning the pro subs). So I cut my sono's in half and ordered 4 more eD 18 inch drivers. I built 8 sealed 24 inch tall and 24 inch round(same sono) subs and I am using 4 behringer ep-2500 amps running in stereo with a 2 ohm load. I do like the sound overall and the bass seems not as powerful but then I took out the spl meter and I was over 126 db's no matter what scene I played. I am very happy and do get flat extension down to 5 hz. Here are some pics of the black canons which I have 2 in every corner.

It started with these, the silo missles.



So I turned them into these:

Holy ! this looks like the future of home theater.

Kidding (refering to the time stamp on the pics)


It does look quite impressive though.

Thanks, you are not the first with the future comment. I still have not corrected the date on that camera. I would love someone near me to come by so I can have a reference point from someone else.

Thanks, the best part is that I can use all the amps I need(not really, I have them turned down,way down) because the graphs I posted have no filters or EQ whatsoever.

Thanks, I used to run pro subs that can hit 110 db's at 15 hz and they were tuned to 25 hz so I knew this room had some serious gain at the low end. Even without it my sealed subs would be flat to 15 hz which is still great.

Thanks, If the rack was not in that corner I would have done all 4 corners like that. I am still thinking about putting 3 stacked in front for 6 in front total with 2 in the back corners.

I like the name. I am really loving the sonotube builds. Looks like you have done a wonderful job of controlling sound and lighting in that room.
