Kyblack76 Posted June 14, 2015 Report Share Posted June 14, 2015 output? how? control? how? cooling? how? power take? how? Little help from the gurus please.. kyle SMD SUPER SELLER The Burban Build Blazer Build sold Acura trunk build sold Link to comment Share on other sites More sharing options...
Triticum Agricolam Posted June 14, 2015 Report Share Posted June 14, 2015 Output: Port area can only negatively effect your output. Once you have enough, adding more won't change anything, but if you don't have enough its going to decrease your output around tuning due to energy lost to air resistance and increased impedance from port compression. Control: Not having enough port area will increase cone excursion around tuning (contrary to what some people believe).

Krakin Posted June 14, 2015 Report Share Posted June 14, 2015 Having more area will allow more air to flow in properly and more air exchanging more cooling. 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.

Kyblack76 Posted June 14, 2015 Author Report Share Posted June 14, 2015 so there is no such thing as too much? Only adjustments ive seen to port area...... on every forum, every build... is SHRINKING... i may be the ONLY one that should open the vent.. and even then.. i bet my gain is dick........ im more worried about cooling, and control. Output... fuck... who cares... SMD SUPER SELLER The Burban Build Blazer Build sold Acura trunk build sold Link to comment Share on other sites More sharing options...
Krakin Posted June 14, 2015 Report Share Posted June 14, 2015 In a perfect environment I don't think that you could have too much, you'll only use what is needed anyway, but not having enough the speakers will try and force enough to come in and out. Air has to be moving, you put your hand next to it you feel it... Air can compress which is known as acoustic compression when having too little. However when you have a defined displacement with a defined velocity you must have the correct area to be able to move the volume being moved by the displacement.

reedal Posted June 14, 2015 Report Share Posted June 14, 2015 I'm with you, I'm not worried about output, definitely not numbers. I build for my happiness, and that happiness would go away if the sub is damaged because it got too hot for too long or went past mechanical limits or something even on rated power.
