When I moved from the 2-subs @ 4 ohms to 3 @ 2.5 ohms, my amp starts to clip at hgiher volumes 15+. Does this mean i need a better amp? My amp is the eclipse XA-1000 rated @ 4 ohm 1% THD 320 watts, 2 ohm 1% THD 480W, the ED 9KV@ requires 200 RMS. I put on ohm meter on my wiring into my amp and it reads 2.5 ohm.
clipping is a bad thing....your amp clipping at higher volumes is a good thing...means more clean power
I wish we could all have an Oscilliscope in our sytems.... then it would be known when a sytem is at its limits. The Good ol Orion amps had clipping lights on them, and were very accurate...Is there a company out there that sells an external clipping indicator??? Or could one be made??????? That has me thinking....... clipping is DC from the power supply of said amp. An audio ouput stage should ONLY put out AC in any situation (escept for esoteric stuff that will actually do DC) Perhaps a few diodes, some resitors, and a few LED's, and a cap or 2 would make a nice little circuit...... Boosted, you say it clips at higher volumes.....The sytem will get a little louder with the addition of another sub, and the more power that is being put out by the amp......As for the numbers on your volume control...I am not sure. It should clip at the same point in your volume control.
uhh are you good at circuits? theres a project here http://sound.westhost.com/project23.htm also theres some info about somebody building something here http://www.diyaudio.com/forums/showthread.php?postid=14808 you have to be logged into that forum to be able to see that picture. dang it. and this project also http://www.sound.westhost.com/project57.htm which was found here http://www.diyaudio.com/forums/showthread.php?postid=612738
The signal is distorted and starts to become a square wave...not a smooth sine wave. like this at major clipping-amp puts out a dc signal http://www.bcae1.com/oscope.htm its just the basics but thats pretty much all I know...also if you play a tone and turn the gain up till your hear it change...thats the wave squaring off...then keep turning it up and it may put out a dc signal Viking will come here and put it in some highly complicated jiberish....just waiting now
amp is it that my amp is not powerfull enught to get the volume I want? I just purchased a JL 500/1, will the be a better solution for me? the amp I have no is maybe 400 watts @ 2-ohms to drive the three 9KV@ woofers.
You got it. For some reason you are expecting more from the amp than it is capable of. But typically I do not consider a couple of hundred watts as a big improvement (unless your starting with a 100 watts). Go to near doubleing your current output. Also you want a really big improvement, redesign your box. You will get 100 times better performance from a box design than you will ever get from an amp swap. My 10-cents worth anyway
According to Ed the box internal volume and port are correct. The box bangs big time, but the amp can not hndle higher volumes. it is 1.7 CuFT with a 2.o" vent tuned to 32 HRZ. Alex at ED said that the design os fine for these subs.
I was told the 500/a has been tested at 733 watts, 600 is a normal rating as per some other tests, copared to my 400, I think that is great, no?
