Low volume bookshelf spkrs that go from 20 to 20k?


Hi folks, My daughter (9 years) is a discerning listener and a trained singer. I want to reward her with a nice stereo system. We listen to music at low volumes. I plan on buying speakers on my next trip to the US (daughter can not audition speakers). I do not want to compromise on quality but have a budget of about $ 1,500 for the speakers. The size of the room is about 14 feet square.

Speaker requirements:
Freq response: Should cover the audible range (20 to 20khz). I think this will keep my daughter happy.
Model: Bookshelf preferred (small room)

My questions:
Will I need a sub to complement the bookshelf speakers?
Are there bookshelf speakers that cover 20 to 20khz?
What models would you suggest for bookshelf and if required a sub. A 220 volt power supply for the sub will be ideal but not a must.

Appreciate your suggestions.

Narrod: A 20hz soundwave is 27.5 feet long. It simple can't be achieved in a small room though the apparent bass can be very good in a properly treated room.

How are headphones able to achieve low frequencies?
Check out the Yamaha piano craft sereies. I wanted to see if I could put together a reasonable system at Best Buy.My friend asked me to reccomend systems for them but they always balked at highend prices.
After spending a couple of weekends at Best Buy I purchased a Yamaha cd reciever and two Yamaha powered subs(you could get by with one). The sound is amazing for that price range. ($400 for the system and $250 each for the sub.)Throw in a nice set of earphones and call it a day.
Now when my friends ask for a recomendation, I can take them to the bedroom and let them audition it right on the spot.
For an uprade you could substitute the the $399/Epos mini monitors.
Thanks folks for all your advice. I auditioned monitor speakers from the following manufacturers:
Spendor (similar to the Harbeth, but lacked clarity)
Dali (great sound but price was about $ 4000)
B & W (inexpensive but did not sound right)
Paradigm studio 20 (good but perhaps too big for my room)
Harbeth - liked them, price was within my budget too.

I ended up purchasing a Harbeth PS3ES-2 similar to the LS3/5a.

Thanks again (got to get the karma right)
