Hi, can u please tell me if my port dimension will be OK? the supplier catalogue is saying that a vented box should have a net Vb=3.5ft^3 and a Vent dimension of: 4" ID and 7" long, port area is OK? I used online calculators and found out that with such port dimensions=> my tuning freq is...

Hi guys i own a clarion pxw1552 DVC, 15",each coil is 4ohms, total power of 750rms, 1500 max power. those are the specs: Fs=23.28Hz Qms=5.927 Vas in(L)=193.07 Qes=0.6018 Qts=0.546 Vd=0.21ft^3 Xmax=12.5mm . . . the supplier catalogue is saying that a vented box should have a net...

Anyone please?? i am very spectical about bying woofers before having the chance to listen and feel the bass they output. The problem is i am gonna have it shipped to my country, so i dont know how they will sound. I have a 15" SVC Clarion woofer/ 300 rms, the ones i am getting are DVC 750rms...

Hi i am getting the Clarion subwoofers PXW1552 dual 4ohm coils, 750 rms. I wanna know if some of you have already tried them....thx

Hi, i have a 15" clarion sub with following specs: Qts=0.27, Qes=0.28, Fs=26.5, Vas=48.0253Liters, Pmax=600W, Xmax=7.5mm, and i am getting a sealed box volume results of 8.4Liters, thats too ****ing small for a 15" no??? where is the prob?:S Thx

Thx guys, thats what i though was true, battery will **** the amps it needs, so it ont fry. But i used to use some Battery chargers in my house and there is a button where i can increase the ampere....to pick a fast or low charging rate, and they always recomended the low rate. Whats the...

Well i have a monitor in my car and on the bass, boum the monitor light is dimming a lot i dont want it to fry out man. i want to get rid of this voltage drop, by having more current ( juice), when the load needs too much current more than what the source can provide, this will result into a...

Hi, lets assume my battery is 50 ampere-hour, and i have a load of 20amperes( lights...) the alternator should at least provide (50+20)/3=23.33amperes? many people tole me i must add the total load and alt must provide at leat 1/3 of the load. In some site they say: charging rate is between C/10...

Dont be too accurate and start thinking how to hit the 30Hz with sub filter lol. just set it somwhere in the midle of the frequency range of the sub filter:D:D:D

dude if u have a seald box, turn off the subsonic filter, for a ported box i guess around 30Hz if u dont know ur tuning box freq bla bla bla....u dunno how to use a dmm???:S well just pick AC voltage on the DMM and start testing. It has the following symbol ~ V, where ~stands for alternating...

Geezzz, y am i always having verrrrrrry poor results when setting gains using a 0dB,-3,-6,even -10dB test tones( specially with woofers, they are barely moving)...now i am only setting gains by ears, after setting the amp i tried to insert a test tone and used a DMM i had voltage double then the...

Thx for all of u who have replied...i only set my amplifier gains by ear( listening to music) i always had very very poor results when i have used those calculations+ test tone cd of 0dB, i always set my gains very far from what the DMM method requires....and i have never burned any...

How can we consider the inductor ( voice coil) a simple resistor? in AC current the power P=V.I.Cosine(Phi) and the cosine(phi) is equal to 1 only when we have a pure resistor not inductor:S there is the apparant power, real power etc...so heh i am lost baby. we are considering the inductor as...

anyone?

Hi, how are we saying that P=V.I =v^2/R and that V=R.I, well we have AC current not DC and also the speakers voice coils are inductors not resistors right? . With AC current the voltage and current are not in phase when we have voice coil ( inductor) its not a simple resistive circuit. Can we...
