napatunog ko na yung Dr20W without any problem (dritso) maliban lang sa madaling uminit yung heatsink, bakit kaya?

ito video:



4" 20W @8 ohms yung speaker na ginamit ko. 3A 20-0-20V yung  trafo.
Good job bai pendot! +1 syo

madali talagang uminit ang heatsink niyan,  kung hindi pa naman napuputol ang tugtug di pa naabot ang thermal protection.

yes po sir Dandy,.pero hindi ko nakuha  ang gusto ko sa crossover from EE. ang gusto ko kasi ehh pag LOW - bass lang sana at walang boses ang madidinig at saka sa high. :) :)

pag aralan ko muna sir by substituting caps at res value. :) :)

I see...  we're looking forward to have an active cross over,  anyone to share, and I can make the PCB for it along with the parts.

Sir Pendot : Try nyo yung linkwitz relay crossover sa ESP site. Tapos yung board layout meron dito

You can find a single board implementation of this crossover here. Complete with PCB layout, bill of materials etc.

Thanks Sir for the Alert . . . . .    Wires are from China is not standard, how many got this kind of wire?   

Use voltmeter to know the correct polarity then, not on the color.  Salamat uli.

Double check talaga dapat during assembly/soldering...

I only used voltmeter if ayaw gumana...:P
