I will paste the response I sent to Drunk 24/7 in IM, since it is relevant to your request:
Working within $500 Canadian(Note, I am not familar with Canadian retailers): 2x Primus 150(or Primus 140 if you need less space occupied) bookshelf speakers. These speakers have been measured by 3rd parties(such as Stereophile, refer to the measurements at:
http://www.stereophile.com/standloudspeake...ity/index4.html )
This speaker is superbly linear for the price(as cheap as $120 USD for a
pair in the USA). I recommend the Primus 160(a 6.5" 2 way, as opposed to 5"
2 way) if your desktop can handle the space. All of the Primus line speakers
are designed for identical pattern of linearity among each other; you simply
choose the one with the SPL/bass output/physical size that suits your
application(s) best.
Note: you can further increase the sound quality of the Primus speakers with
some easy cabinet modifications, such as replacing the internal acoustic
damping material with a more effective one, and adding a material like
Dynamat to the cabinet walls.
You need an amplifier, of at least 35 watts(for nearfield use) RMS output
per channel into 8 ohms. I recommend, for the cheapest solution, use Ebay
and look for a vintage stereo reciever from the 80's or early 90's, from
Onkyo, Pioneer or other reputable maker. In the USA, I can find solid 80's
Onkyo stereo recievers for around $40.
You need to crossover the Primus 150 at about 100-110Hz at 4th order, to a
crossover, for optimal sound quality. You need to crossover the Primus 140
at about 120Hz at 4th order. You need to crossover the Primus 160 at about
80Hz at 4th order. Obviously, the larger unit you get, the lower the
crossover frequency required, and easier the subwoofer integration, and the higher distortion free output can be achieved. Coupled with the subwoofer I recommend, this system will certainly be able to deafen you near field, and provide superb sound quality(relatively speaking) to boot.
You need an amplified subwoofer. I recommend(for cheapest, but still decent
unit, and with solid cabinet and amp that can be re-used later and upgrade
the driver and re-tune the port) the Dayton Audio 10" or 12" sub-woofer.

signals out to 'small' speakers and a 'subwoofer', and can specify the
crossover frequency).
Accounting for the shipping from the USA for the Dayton subwoofer, your
amount should be right around $500 Canadian. If you are interested
in the materials for modification, I can specify the optimal materials.
