Bro, hindi ko na matandaan kung same channel. Ano ba possible issue sa speaker, shorted? Tumagal naman ng 3-5 years yun amp bago nasira. 11-12 lang din ang volume setting ko kasi sa loob ng bahay lang.
Thanks for the warning.
Unbeknownst to some, voice coils heat up during operation (especially bad with tweeters and midrange drivers) and overtime, develop shorts in the coil. They still work though, but their DC resistance drops and gets worse overtime. This is partly one of the reasons why there was a marketing heebie-jeebie about tweeters having so called "ferro fluids" that serves as coolant for the coils. Anyway, this provides a heavier load to your amps and will make them work harder. The bad thing here is that you'll never know until it's too late.
Nowadays, 3-5 years for an amp is "sulit" na and sometimes mas mura pa nga magpalit kaysa hassle ng magpa repair sa service centers. Ang kalokohan kasi nila diyan they use linear volume controls instead of logarithmic to make it seem so that kahit kaunti pa lang ang volume mapapa-wow ka na sa lakas. Ang problema, hanggang dun na lang yun, pag nilakas mo pa basag na ang tunog, in audiophile lingo - walang headroom.
Sana nga masupil na nilang lahat yan mga fake, hindi naman fake pinambabayad natin pag bumibili tayo eh.
