Now let's have a look at what's listed:
Warm = Good bass, adequate low frequencies, adequate fundamentals relative to harmonics. Not thin. Also excessive bass or mid bass. Also, pleasantly spacious, with adequate reverberation at low frequencies. Also see Rich, Round. Warm highs means sweet highs.
Opposite of warm = cold. So cold = thin, lacking in bass, not rich.
Cold tends to be bright and shrill.
my mistake then , but , i will still call it cold , i think i can write one on my own . read the disclaimer , he doesnt claim these are the constants or any thing ( though i will agree to most ) . and theres no cold there .
