I bought these speakers to plug into a PC (with good Sound Blaster) together with a small digital amp equivalent range of SMLC brand. What to expect from brand libraries pregnant "unknown" at 160 Euros? In the case of these "Polk" really not much: the bass is almost nonexistent, the sound is certainly clear and detailed enough but nothing more. At that price Altec type of PC speakers are a much better deal. Also they are quite bulky and heavy for bookshelf speakers. To sum up I really do not recommended them.
