Now that I have the 7.1/5.1 figured out.. I thought HD was always discrete 7.1... owell moving along...
problem 2 is clipping. for movies, as expected, I have WAY too much power @ 40hms...which is why I ordered dual 4's... so I'll *only* have 3X the power I need at 8 ohms. But right now, with movies, the sub still has too much excursion with the gain only on 14... but for music I have to turn it up to 26 to get resonable output. At 26 the sub wants more, has plenty of room...but the amp starts clipping a touch above that. 2 more clicks and it clips HARD on higher frequencies but not lower. So is my electrical bad? I have RCA to XLR. I have the receiver sub maxed at +12.5dB.
So anyway, I no longer have my helper ( NOT my wife, NOT my girlfriend...a really nice gal..that is a friend of mine..I am just as unconventional in every other aspect of my life
I don't have girlfriends or wives
Now I know many people are gonna say "how about port support!" but I am not sticking with a 6.5Hz tune! Read the entire thread before posting! I need a 5" long port with a 12" sonotube in 125 cubic feet for a 15Hz tune! 5" port length! 10Hz I think was 17"... I am leaving 5" of overhang on the outside so that I have 2 free ends... 11.25" will be just fine...but I know I will hear just as much over that as I have over my bracing. and NO I am NOT bracing anymore than those 2 little 2x4's making that X... thanks for the ideas, thanks for the suggestions, but you can say I told you so after the box explodes.
um... didnt mean to upload these but may as well post... I overcaulk initially, always...owell... then after it cures I usually go back and put a 2nd layer in the corners and smear for extra support and air tight seal...then a 3rd. Only 1 extra layer this time...it will make it easier to finish pulling them apart after they implode due to lack of bracing.
also keep in mind, these 12" ports may be taken out and increased to 14" 16" or even 18" if they can't fully support 22's
