difference between voice coils

That was run-of-the-mill advice.  Here's some good advice: 

Are you happy with your system?  Do you like the sound?  Does it make you happy?  Is it loud?  Are your friends envious?  Do your neighbors know you're coming?

If any or all of the above is true, just tell your friends that those Audiobahns are putting out 1000 watts each and leave everything alone.  Only you and God will know the truth!

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

geepherder, I could pass my MECP on just what I've learned from you!

And, of course, my answer didn't reflect on your post but just on mine.  Actually I didn't even see the edited addition to your post...I saw it at the point where it ended with (Yes, they do make them.)   I would have chosen different wording if I did...:)

But anyway, to the original poster:  Cheers, and enjoy your system.

I don't mean to keep dragging this out, but I want to point out a misunderstanding you have here.  Just because a subwoofer (or any speaker) has a rating of RMS wattage, it doesn't mean that you have to fullfill that rating with real applied power.  Half of the RMS, or continuous power handling rating, is more than enough...and in SOME cases is just exactly what you should be giving them.  500 watts to those subs will make them perform as well as they can do.  1000 would more than likely destroy them.

Oh yeah....and to avoid any lying at all, just say "These subs are each 1000 watts and this Memphis amp puts out 1000 watts!"  Everything you said is true and you leave the number-crunching up to your audience.  Who knows, they might be thinking 3000 watts after you say that!

After I wrote this I saw your new post.  This thread is finished so it would be best to start another with your new line of questioning.  And, BTW, I will just finish this with saying that it would not be wise to add another 1000 watts.  You would be doing so only if none of the questions I asked you above were true...and if they aren't you should be considering some other improvements rather than adding more power.

Cheers, and this thread is dead.
