  1. What do you think?

    ive been lookin at it for the last hour and cant decide what i wanna do. obviously would do a t-line for either of them. just cant decide if i wanna go with less cone area with less efficiency with more power or go with more cone area, more efficency, with less power.. also would need a bigger box for the one 15. but i think the 2 tens with the higher fs would have a better all around sound. Also the 1 15 is going to be moving way more air, but idk if that will have any kind of diffrence.

    "An efficient speaker helps you maximize your available wattage. Believe it or not, a 3 dB increase in speaker sensitivity produces the same audible increase in volume as doubling your amplifier power. So when you're shopping for speakers, it always pays to check the sensitivity spec — especially if you have a lower-powered receiver or amp. "

    the tens have about a 5 db lower efficiency then the 15 has. so that right there make wattage even out.

    lets debate it.

  2. you can go to a hardware store and get "weather stripping" its a roll of rubber with a flat side that has tape on it. Open your window and put the sealing on the inside of the window so when you close it the one roll of rubber lands on the other roll of rubber. it may be a bit harder to close but you'll make it air tight and it wont make any noise.

    one of the ways we got Mr.P to 152.2 db :)
