At this point there's a thing I'm wondering about.
Considering the following isophonic curves
showing the behaviour of human hearing at different sound frequencies and pressure levels (the lowest represent the average perception threeshold, the other are for sounds perceived as having equal intensity), I have to deduce that spectrum analyzers used for trace out frequency response curves for studio monitors have to take the isophonic in account, and not use the simple db sound pressure level values.

This explain why bi-amplified reference monitor speakers have amplis with huge differences in power for basses and highs
***ADDED***
Not just for that.
Bass freqs need more power than high, even to reach the same sound pressure level (like even in telecomunications a cell phone operating in the GHz band need more less power than a citizen band transceiver operating in the MHz band, to cover the same distance).

on those curves you can see the ear's response to frequencies below 70Hz is really bad.
These frequencies are perceived by the body (solor plexus region in the first place, if my memory serves correctly), so as already mentioned one needs big monitors for simulating the club PA sensation.
For the playback on 'crappy' 2.1 systems and the like (imho) you'll quickly get the experience to corelate your monitor sound to what it sounds like on that gear.
First of all (most of) that gear isn't exactly quality stuff, and second it's owners don't care anyway (otherwise they'd bought something else)
cheers, Tom

I may be a simple guy, but I'm very glad with my active (ADAM) subwoofer, and I didn't change anything to my room.
I know I should, it would help a lot to get a better sound impression.
Still it's a great help when balancing the subs in comparision to the rest of the sound
What I wanne say is, to have a subwoofer in an untreated room is still of much more value than without...
I just activate the woofer when I wanne have a close look to the subs of the sound, I don't need it when just working on a song

Once I bought a cheap Altec Lansing multimedia speaker system. 2 satellites and one powered subwoofer.
The subwoofer survived and today it is just connected at the tape rec out of my amplifier.
It is enough for me to get an impression of the body of a track.
Also it worked on smaller live jams very well.
I will not miss a subwoofer anymore.
