  • ulit ulit. anung gusto mong mangyari projectdimpreza?
  • tangalin ko sna sa setup ko ung ktm-12 instrumental, papalitan ko ng sw-125 or sw-1236 ng crown.. mga subwoofer kc to...

    kaso ung sw-125 4+4ohms ung sa specs nia.. pwede pdin ba un? kc ung midrange ska tweeters ko 8ohms e.. pwede koba isama sa crossover board ung sw-125?
  • It is possible, you can still hear a sound but it is a wrong design if you are using a 3-way CNB. The rolloff frequency for the low circuit about 800Hz which is not designed for subs. Subwoofer at least in the range of 30Hz to 100Hz. That is why if you see the label for the connectors says woofer not subwoofer :)

    Subwoofer requires different filter board to get below 120Hz to get that

    Analogy to this putting salt on your coffee. It doesn't taste good but still drinkable.
  • Correct.
  • pwede kopo ba isama sa crossover board ko ung SW-125 ng crown sub? sa specs po kc nia 4+4ohms cia.. kc ung tweeter ska midrange ko 8 ohms e.. sa pagkakaalam ko po dapat puro 8 ohms ang ilalagay ko sa crossover board?

    Subwoofer po yan SW-125 nyo eh. So you need to get a CNB designed for a subwoofer. As for the 4+4 ohms na sinasabi nyo eh dual impedance po iyan sa iisang speaker. You just need to wire the terminals in SERIES to get 8 ohms total output.

    Simply solder or short one Positive to Negative terminal. So you end up with one positive and one negative terminals na parehong OPEN.
  • @ fortoz

    tama po kau woofer nga ung label ng CNB ko pra sa LOW. i guess i need to get woofers.. instrumental kc ung nabile ko.. asar kc.. sa specs nung ktm-12 subwoofer pero instrumental pla cia.. namali tuloy ako nang bile.

    at panu po if i get a subwoofer cnb? panu na ung 3way cnb ko? could i still run the 3way and the subwoofer cnb together? halimbawa po ung mid at tweeter nlng ang nkakabit sa 3way cnb.. bakante ung sa woofer terminal nia.. tapos magkakabit ako ng subwoofer speaker dun sa sub cnb ko? pwede ba un? panu po connection nun lahat sa ampli if posible?

  • mas maganda ang instrumental kesa standard woofer. ang instrumental pagpinatigas mo malinis pa din. ang woofer patigasin mo pagalpal.
  • @ ron1221

    what do mean po pag "pinatigas" lol??? panu neo po nasabe na mas maganda instrumental sa woofer?
  • baka po matulungan nyo ako. Nung una kasi naputol yung mga pins sa likod, so mga ilang linggo ko di nagamit dahil ayaw mag power. As seen on the pic below (the cable that has the label "Right")

    Ngayon di ko alam gagawin ko pinutol ko mga pins na baluktot para ma plug ko yung cable... siguro mga 4-5 pins na lang natitira.. ayun napasok ko naman pero ayaw mag power. Ano po kaya problem at ano ang gagawin dito?
