[QUOTE="Beentown, post: 8506762, member: 669477"] Yeah, I get the generals and thanks for the clear post. The thread was more of my surprise in the change of how SPL rigs are built now. Less subs and WAY more wattage. Makes sense (after reading on how much amps and subs have developed) but a complete change from what used to be on top. An entire different direction. Just really didn't know how the multiple efficient subs stacked up against high wattage subs with similar power in today's comps. Example for clarities sake: 12-12" subs that are more efficient being fed 6k watts or 4-high power subs with the same 6k. Seems to me the new (well, new to me) wave of SPL subs being feed plenty of power are the way to go. I am sure the rules for SPL events determine this to some point. Used to be that classes were determined by amp RMS rating into 4 ohm (why I ran two, Soundstream 10.2's). I have read that classes are done by cone area and/or measured wattage (don't quote me). Just like before it is space available combined with wattage you can run will determine all. All the rest is design and selecting the right components to match each other. Still a bit blown away that subs can handle that much power and wattage is this cheap. I have a Pioneer P1R in my man room...maybe I will use it as my HU. [/QUOTE]
