Monitor Lizard

[massplanck]

Ok. Just got a set of Alesis M1 MK2s (I know tis all i could afford for the time being) and true to nature they are as boomy as **** and I dont think I like them (yet). At least now I have two sets of speakers (old one being nice wharfdale hifi speakers & a pioneer amp) to monitor on.
The room is an ok size. I'm just wondering where to place them in relation to the wall. I have no stands right now (well I do but the are only big enough for my old speakers) so they are gonna have to go on the table with the rest of my kit. I have heard its a good idea to raise them up a bit and have a bit of air beneath them . So i'm gonna jam a few Java & Python mega programming manuals under them to let them breath. Good idea or not?
What i want to know is.. should i pull the table a good bit out from the wall or ram it right up against and leave zero space between the monitors and the wall? I have heard the later can be good choice when you dont know what the **** you are doing (ie me).

Also I tried creating a continous sweep from 40hz up to 16khz in wavelab so that i can figure out if I'm missing any frequencies where I am sitting but for some reason wavelab refuses to make the sweep last longer than 10 secs no matter what settings I give it. Its pretty annoying. Does anyone know where I might get a wav of a sinewave that sweeps up for about 30-40secs?
