50db/watt at 100 watts = y
I'm not an expert on this stuff by any means. If it copies/pastes well, I made a little spreadsheet. Middle column starts at 1 watt. The left column is an 88 db pair of speakers (at 1 watt) and on the right is a horn loaded pair of speakers that are 109 db at 1 watt.
Look at how much power you need for the left spekaer to hit 109 db's (about 128 watts). The horn speaker hits that at 1 watt.
Think about it a different way.... if you are driving a Honda Civic and trying to pull a full sized loaded trailer behind it.... it might do it. It might have some acceleration issues.
Take that same trailer, put it behind an old muscle car of the 70's and that car will not only be able to pull the trailer effortlessly (lower speaker distortion) BUT, it might also be able to out accelerate a normal car while at a stop light!!
Ask me how I know... I used to have a 1971 Olds 4-4-2 and had a trailer behind it after leaving college. I could easily keep up in traffic and if needed, easily pass people WHILE still pulling that trailer.
