SCAM ALERT For AudiogoN Sellers - Too Many Questions

Component placement for open baffles?
I design loudspeakers I use the back wave to load the room with low bass pressure as a back-loaded horn would. My OB system is 2:32 in.

What is your take on high efficient speakers vs. low efficient speakers?
It's just wrong to think that hi eff doesn't do low bass I have bass horns that can bend doors and make your eyes resonate some I designed are used in military simulators to replicate explosions and gun fire. Just because in your limited experienc... 
What is your take on high efficient speakers vs. low efficient speakers?
I use most all types of amplifiers inc SET with a 6-watt SET I have horns outputting a solid 30hz and getting room lock. Those dissing SET never used them or they SET their system up to fail.
