bluetooth or wifi speakers for your audio system?

the coming of smart speakers, i saw it coming. apple has new homepod speakers, google has google home and amazon has amazon echo. you may want to know if there is a difference between bluetooth and wifi speakers.  The choice of Bluetooth or WiFi is clear. Bluetooth is a universal standard and easy to use. But, its range is quite limited and sound quality is restricted. WiFi systems have a wider range and can offer excellent fidelity. But, different systems that use WiFi are incompatible, and setup may be difficult. more information on the above mentioned smart speakers can be sought out here:
