I have a pair of Swans M5A’s. What is the best wireless powered sub to integrate with them for 900 USD or less?
Any sub you like and then add send&receive unit’s to make that sub wireless is option as well.
Example: SVS SoundPath Wireless Audio Adapter
Decent units usually are prices around 100-150.
Things to consider.
If you have plenty of mobile, wifi etc (2.4GHz) household devices between or near the source and sub location. There might be interference’s / issues with the connection.
Only way to know is to test.
