HHR Ed Posted August 10, 2012 Report Share Posted August 10, 2012 I laid out my thoughts on it in the vid. Does anyone have anything to add or subtract to the subject?

87chevyboi Posted August 10, 2012 Report Share Posted August 10, 2012 that was quite informative and ive never really understood box rise and all that but now i understand a little more than i did before lol Quote My build aka Snow White whats wrong with fat chicks? they are like mopeds, as long as your friends dont see you riding it, they are a blast! hahah I am dumb as a stump. I live in the south and we are all dumb here. Link to comment Share on other sites More sharing options...
HHR Ed Posted August 10, 2012 Author Report Share Posted August 10, 2012 Thanks guys. I didnt really go into full explanation on how various enclosure characteristics effect impedance. There wasnt much time for it and as you can tell, I mentioned that for daily music, its not important to know most of the time.

Kyblack76 Posted August 10, 2012 Report Share Posted August 10, 2012 Very well done Ed, Seems some out there are very very rise dependant...... Or,.. think they are. Great job.

bassface Posted August 10, 2012 Report Share Posted August 10, 2012 Great video man, now you mentioned amplifier circuitry that battles impedance rise. What is the name of that circuitry?. Seems the amplifier would be more important in this than a box, because the amp would fight it at all frequencies right?. After watching the video it does seem unless you are a spl burp competitor its almost a waste of time to worry about impedance rise caused by the enclosure.

After watching the video it does seem unless you are a spl burp competitor its almost a waste of time to worry about impedance rise caused by the enclosure. Amplifiers have an output impedance which will controls the voltage drop on the voice coils. To have a flat voltage, this output impedance must be low. The lower, the better. This is often called "Damping Factor" I believe the RF CP has a firmware which controls a dynamic output impedance and can adjust output current in real time.
