Passive speakers - ordinary Hi-Fi speakers
We recommend Pioneer SP-BS22-LR speakers. They work very well with the Wi-Fi network music player IQaudio class D amplifier that is used in Network Music Players. Considering the pretty decent price, these bookshelf speakers offer extraordinary performance and remarkable quality to deliver a phenomenal music experience.

There are of course more expensive and potentially better speakers on the market. If you are prepared to spend over $200 USD we recommended considering these speakers:
Q Acoustics 3010i, made by Q Acoustics from UK.
Elac Debut B5.2, made by Elac from Germany.
At the other end of the price spectrum, maybe consider used speakers? There are many excellent unused Hi-Fi speakers out there, in basements, storage and garages. Check out eBay and other Internet place, thrift shops or garage sales, and you might make a real bargain.
