Keith77 Posted March 9, 2015 Report Share Posted March 9, 2015 Build a new box and tune higher around 33hz will give you more output Thats cool. Im way too old to be upset by shit like that. Your name is winston. Your own parents hated you even before you were born. My penis is bigger than your penis I'm far from loud and my roof/headliner flaps around like Adam's ass on a windy day. I think it depends more on the structure of the vehicle. Link to comment Share on other sites More sharing options...
Broke_Audio_Addict Posted March 9, 2015 Report Share Posted March 9, 2015 I honestly am surprised those x's are taking that power, kind of makes me think you got some issues with the install. I also second a different box. That being said a lot of people's definition of "music" is a clipped 30 hz sine wave with some 80 IQ knuckle head grunting about committing crimes and his genitals.

Afficionado Posted March 9, 2015 Report Share Posted March 9, 2015 I honestly am surprised those x's are taking that power, kind of makes me think you got some issues with the install. I also second a different box. Yeah, I had the 2x x-12's on about 1700 each RMS and that was plenty. I also had a box that was about 5 cube, and ALL I did was reduce box volume by a cube and I gained 1.6 db. IMO it was partially increased box efficiency and partially raising the tuning freq of the box. My 2x X-12's on my single T2500 bdCP did a 148.2 legal, but my friend who did a 147.6 on 2x Rockford 15's sounded WAYYYY louder. You'll be louder with a higher tuning frequency. If you have any questions relating to nutrition, lifting, or health in general, feel free to give me a PM and I will give you straight forward advice with no BS involved.

Krakin Posted March 9, 2015 Report Share Posted March 9, 2015 Doubling come area is a 3 dB increase. Doubling wattage is a 3 dB increase. It takes 10 dB to sound twice as loud. You won't notice a 3 dB increase on music. Redesign your box after you research done about how to even build a good one. Krakin's Home Dipole Project http://www.stevemeadedesigns.com/board/topic/186153-krakins-dipole-project-new-reciever-in-rockford-science/#entry2772370 Krakin, are you some sort of mad scientist? I would have replied earlier, but I was measuring the output of my amp with a yardstick . . . What you hear is not the air pressure variation in itself but what has drawn your attention in the two streams of superimposed air pressure variations at your eardrums An acoustic event has dimensions of Time, Tone, Loudness and Space Everyone learns to render the 3-dimensional localization of sound based on the individual shape of their ears, thus no formula can achieve a definite effect for every listener.

So if that's the case why does a 150 and a 155 feel and sound like whole different worlds?I shouldn't notice unless I went from a vehicle that did 50's to one that does 60's right? But fact is you can and do notice a difference at less than a 10 db increase.

ALPINE408 Posted March 9, 2015 Report Share Posted March 9, 2015 After 145 dbs every 3 db is noticeable difference Doubling power doesn't = 3 dbs increase it all depends on the installation if had up to 5 dbs to as low as .5 db increase when doubleing power To the op no matter what you do you will get use to the bass and will always just want a little bit more Have you ever had your woofers blown?

Krakin Posted March 9, 2015 Report Share Posted March 9, 2015 I wasnt aware of the 145 dB thing. I didn't say you wouldn't notice till 10 dB I said that is when it should be perceived as around twice as loud.
