From the original SUBMAXIMUS build thread
ME ! From 6-26-14 :
I just so wanna build another one SOOOOOOO bad . . .
From @Mfusick same day: Build another one. That would be epic.
From @LTD02 on 6-28 :i don't know if i'm 100% happy with the way the very bottom turned out on this one. i was hoping for a little more loading and bit more low end sensitivity. ah...my own worst critic i suppose.
@Mfusick: That is the idea that intrigues me. I want to build a really big horn that digs down that extra octave. I know it takes 4x as much space but I think I could pull it off. If I could not get that extra octave then I will probably abandon horn idea. I am not interested in doing something average
@kevings :you are the kind of guy i like having as a neighbor! ( i love the lets over do it attitude )
And @Mfusick again:So design up another... and I'll build it and test it. How's that ? But make it even more awesome so I can wreck my house with a few of them. The only issue I have is one dimension needs to be like 30" to fit behind screen wall. A few more inches probably ok. But the other dimensions can basically be about as big as you want. If you walk me through folding process that would be super cool. This idea and subwoofer is just too awesome to let it die. It needs a version 2.0
and @kingpin111: Building vertically doesn't take up much real estate.
Fast forward 2 years . . . >Yogi Berra : It's like deja vu all over again.
Only it's not
From THE V3 post #67 per LTD02
the model has the motor detuned significantly because of the inductance effects (and the cab was modified from the original for that reason). the driver may not need quite that much detuning, but it shows that the horn will have a great response even if the inductance effect significantly limit the effective motor strength. de-tuning the motor of high inductance drivers for horns was given an extensive treatment in a paper by diyspeakerguy. a search should pull up his post and the paper that several of us contributed to on the topic. bottom line, i think that we have a pretty close model here. my guess is that room effects are going to have a much greater impact than the margin of error in the model at this point.
also, be careful with this much output, as it can damage hard drives and other equipment that is sensitive to vibration damage.
And finally:
