currently i'm using the ht-"something" by crown with 2" voice coil and only the 4uf nonpolarize capicitor attached with it. no dividing network. . . i set the frequency from 2k to 3k in my crossover sir. . .
good pm ,
anybody used crell ca 20 amps? is it true that it tends to have dc voltages in it's output thereby damaging speakers? most forum members in another forum site tags or brands the crell ca 20 as "takaw dc out" and "tiga sira ng subwoofers" and they brag more on crown's lps series amps.
thanks and more power..

crell, lexus, musik focus, seems to have bad reputations of frying woofers, maybe clip indicator not accurate?, or the output sticks to much at rail voltages during clipping causing dc, what about phonic xp series? our xp3000 seems ok still running and not frying the dual 15 tops, next test on the road will be xp5000.
if you want your woofers to be burn-out proof, then you can series connect 2 x 22000uf/100volt electrolytics in series with your woofers, this will prevent dc from reaching your speakers when clipping.....
many amps used for mobiles are always abused that it why these things happen....
sir tony msta na?, nice idea but hows the bass performance with this caps?, thanks
thanks sir, crell and lexus are the most brands i see in those iloilo battle of sounds and i see them clipping in their videos!! maybe there are lots of subs fried in iloilo already? and yet they even use ca25, anyone from iloilo here? i'm just curious coz many seems to say that it fries subs and yet in iloilo they abuse it.
At 20HZ, the caps will present an impedance of 0.72 ohms which is 10 times lower than your woofer's impedance.....plus you get that peace of mind that your woofers won't burn out because of dc....
An externally hosted image should be here but it was not working when we last tested it.[/QUO
what made ur dog drop its jaw sir jojo?
my bad.. i forgot that capacitors have lower reactance as frequency increases..
@volmax audio
try using a 2uF/250V cap in series with a 3-6ohm 20W-30W resistor, you can experiment with the value of the resistor to balance the output of the compression to that of the woofer. Thou it will shift the crossover frequency a bit, try to set your electronic xover frequency a bit higher (i.e. 5Khz)

I don't want to sound bad, but that's a sign of a poor baffle construction, A well made box box stands firm and solid even at an ungodly output, Ibig sabihin hindi lumalapat ang 4 corner ng box sa ground. Just my two cents.
