RE: SINE BASS mixing problem.

Take a deep breath and sit down for this:
If the bass is too low for you to hear, then it isn't a very important part of the mix, and should probably be cut.
If you are making dedicated 24-bit DVD audio club mixes or hollywood movie soundtracks that require significant subsonic content for explosions and dinosaur stomping, then you need a good full-range monitoring system. Little nearfield monitors won't cut it, there are no two ways about it, and there is no way around it.
If you are making conventional music recordings for popular release, for people to listen to on home hifis and car stereos and ipods and the like, then very low-frequency stuff is not going to be reproduced by the playback systems, and is going to take up a lot of your headroom. Best case scenario, they simply won't hear the bass, and your record will sound 12dB quieter than everyone else's because you have all this useless subsonic content eating up your dynamic range. Worst case scenario, your record blows their speakers. Most likely, what will happen is that those subsonics will overdrive the amplifier but not be transmitted by the speakers, resulting in a distorted, warbly playback, something like compressor pumping or running your whole mix through an LFO.
Most conventional playback systems, even ones with subwoofers, only really reproduce frequencies upwards of between 60-150 Hz, depending on the system. Moreover, below 200 cycles or so, human hearing tends to be very vague and poor at pitch perception, and people tend to "feel" rather than hear the bass. A little bit of content down there goes a long way.
There are techniques you can use to get that "throbbing" bass sound or the "punch in the chest" kick drum using commonly-reproducable frequency ranges. The Good Lord created tone controls and subwoofer controls for a reason. Let your audience crank up the subsonics if they have the equipment and the desire to do so.
That's my $.02, anyway.
Cheers.
