Both systems you mentioned will not play loud. Get some horn loaded megaphone
In my definition, loud means you are nauseated. I can achieve that with my system at reference level playing Telarc 1812 DVDA, but I don't want to repeat it.
What speaker is 70dB (1w/1m) ? That's horrible efficiency.
The onset of nausea is not going to occur in most setups. Think about it. With efficiency of 105 dB (1W/1M) 135 dB will need a 1kW amp. 145 dB takes 10kW. :Q
It's possible to achieve really loud SPL at low frequency in the cabin of a motor car since you're effectively coupled (like sitting INSIDE the bass bin!) - so 125 dB with 1W is not out of the question. A HiFonics Colossus bridged 4 ohms is 1.8 kW - the max possible SPL would be 157.55 dBUW. :Q
Of course if you really want it foolishly loud you shoot for continuous pink noise output. I doubt any sane human would want to be anywhere near something pumping out 150+ dB of pink noise!
To simulate even louder sounds of LARGE artillary shells, bombs, and other exploding things only takes a pair of headphones and a capacitor. It's rather self explanatory but the results are damaged hearing. Don't do this unless you want to be on Jackass III.
