Thanks for posting! I'm glad to hear you're interested in Google Nest speakers; I'm glad to share this information with you.
Yes, Google Nest speakers are a fantastic addition to your Samsung Tab A9+. Google Nest speakers work seamlessly with devices running compatible operating systems (Android phone or tablet with Android 9.0 or later). This means you can easily connect your Samsung Tab A9+ to a Google Nest speaker to enjoy your audio. Please take a look at the Google Store to choose the one that fits your needs.
