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.While i don't agree as much with other posters on how subs didn't handle as much by a drastice margin back in the day (Kove Armeggedons for example) there is truth to that. But, to put it simply, 2 15's in a slightly oversized box with plenty of port area will destroy 6 15's done wrong in too small of a box, especially sealed. A 15 or any size woofer in a properly sized ported box will usually be 5-9 db's louder than the exact same woofer in a sealed box of proper size and the same amp. I also do not go along with the above poster saying 1w/1m means virtually nothing. It means a lot actually. It means with everything equal, minus a few variables that a woofer @ 85 db 1w will require twice the power to equal one that's 88db 1w IF everything is equal. Keep in mind, an efficient woofer could start out at 99db but not get any louder at 1000w, while a woofer starting at 96 db might continue to get louder up to 5000 watts. So it isn't the end all be all, but it is a factor.
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.
