You might try monitoring your stuff on crap $10 computer speakers, this should give an approximation of the range of TV's internal speakers. Generally you get everything above like 250-300Hz
hi,
very important in producing for tv or radio is to beware the highest possible rate of compression you´re not hearing in the mix.
the possibility of hearing on normal car-audio-speakers is very good.
Sanx Guy's U know,i just've got cheap computer monitors before reading your suggestion,so that nice to be on right way.
Very interesting about compression too.
