I would let your daughter hear the different speaker choices herself. The main reason is that women in general, especially a younger one, can hear a lot higher frequencies that her dad! Do the youtube high frequency sound tests, and you will be surprised how much of a higher frequency range your daughter will be able to detect over you. So a speaker that sounds great to you, with lots of high frequency detail, may in fact hurt her ears. I’ve experienced this hearing discrepancy with my wife whenever we auditioned speakers. What sounded clear and airy to me would sometimes hurt her ears. Consequently, I had to buy speakers that she could tolerate in the upper registers. Hope this helps your search!
Speakers for daughter
I was going to buy powered small speakers for my daughter's first sound system to go with A Project Debut Carbon Evolution but now she seems ok to accept an integrated amplifier from me to power speakers. Thinking about the Elac UNI-FI UB 51 or ELAC Uni-FI Slim B5 U5 after researching similar priced speakers such as the Elac Debut 2.0 B5.2, Paradigm Monitor SE Atom, Wharfedale Diamond 12.1, and Kef 150. I have not listened to any speakers yet at the price point. Any comments?
