LM, TDA Chip Amps is **** Comparing with STK

LM , TDA chip amps very weak bass, but best mids and highs, very weakly produce low frequency.

lot of experiment doing improve bass, but not good result

finally understand usa europe people not like low frequency sound 🤣
 
wrong speakers? 🤣
Maybe, test lm3886 with lg 7inch 3.6ohm oem sub, concrete flow shake, bass not hearing but flow shake

test sony 6ohm 6inch 120w woofer with lm3886 very weak bass , but stk and toshiba 5200 with good bass

Test tda7294 with infinity subwoofer not produce low 40hz to 60hz, hearing 100hz bass

you say wrong speakers , why 5200 and stk with bass , lm tda without bass
 
As these monolithic power amplifiers don't feature any LF roll off at the lower audio band end (why should they?), I ask you why a chip amplifier should have some poorer bass respionse than, say, a discrete power amplifier or a STK thick film hybrid module operating at the same supply voltages?

Best regards!

thermal problem, limited bw, low power with high out,
but why 20hz to 20khz support manufacture say
 
Ci 100uf 16v
Cin 47uf 16v
Cs1 not add
Cs2 not add

in+ in- add 220pf
