I've been thinking about the subs in my home theater for a long time as I know I need/want more. I was also interested in seeing what I could do to move them around my room a bit instead of everything behind my screen wall.
I looked at this space behind my second row of seating and ahead of the rear bar seating and thought about what I could stick there? LilMike's Anarchy design was pretty interesting but the opening fired the wrong way for what I wanted.
Then one day a new member 1800RPM posted the hornresp data for a dual anarchy design he was playing with and I liked the look of the response curve.https://www.avsforum.com/avs-vb/attac...2&d=1297885725https://www.avsforum.com/avs-vb/attac...3&d=1297885725https://www.avsforum.com/avs-vb/showt...3#post20015653
So I decided to build it with only a single fold in a long bazooka shape to stick behind the seating and I named the project Buttzooka.
Instead of working up the design in the digital world, I took an old school analog approach.
I ripped some 7.25 wide boards and some spacers for 4 key areas. for the record the horn lengths are L1-2 20cm, L2-3 323 cm, and L3-4 70 cm.
Then I just laid them on my workbench and figured out how wide everything was going to need to be.
For L2-3 I used a piece of cord and a chinese take out lid to figure out how long various parts needed to be.
Once everything was measured, marked and cut, I assembled the beast.
The beast used a sheet of 3/4 MDF so it is heavy.
And I measured the frequency response with the Omnimic system.
Right now the last side is just screwed on with weather stripping for a seal. When I finish this thing I will round the edges, paint it black and add jacks. If I keep it I'll need an amp and probably Outlaw Audio's wireless sub-woofer bridge.
As for my front wall I have 8 MFW-15s in boxes for some kind of a build to replace my Titanic 15.
