diysmartdeep21's merged chip amp thread

diysmartdeep21 · 9th February 2005, 08:21 AM

I want to use STK amplifier for my 10 inch 120mm magnet 60 watts woofer is stk stable

I want to use the higher order crossovers and like 3rd order crossovers with STK ics

which is the best IC in STK series with 60watts output....

just give me the information regarding this....

best regards,
Sandeep

You need to tell us what impedance the drive unit is as the chips will have a minimum impedance rating.

I need excellent quality and even it must drive heavy magnets woofers>>>>>>>

what is the model number and aslo tell me the manufacturer...

How about STK0060 ? 60 watt continous and 200w peak.

diysmartdeep21 · 9th February 2005, 09:39 AM

impedence is 8 ohms

Should be fine with any chip then.

what ive heard about STK ICS sometimes they fail and all the DC voltage is suddenly appears accross the speakers and they finally blow up !!!!!!!! the speakers!!!!! is this true?

what must be done in order to avoid this ..... give me an advice...

ive heard that if we use the speaker protection ckt then it works firne but give me some links so that ican build a simple speaker protection ckt...

try some ti opa549 with hefty power supply.. will drive almost anything within its power limits, but has only a 36 w power rating.. sonically, its one of the finest amps you can find, provided the project is done with utmost attention to component quality and construction...

Hi sandeep,
Though I am not good at these kind of problems

I would certainly let you know if I learn something. On "how to get around this kind of speaker blowup problem." Meanwhile just try tweaking out with a fuse

rated slightly less the the current carrying capability of the speaker coil.

Peace

Deepak
