I know powered speakers tend not have as good sound as wiring regular speakers to an amp yourself, but these will be for a TV just for gaming/movies. I already have a much better, real audio system for my computer for music listening. Here's what I found researching so far:
Plugable LYSB01KGPEW70 - one 4" glass fiber cone woofer and one 1" silk dome tweeter https://www.amazon.com/Plugable-Subwoofer-Bluetooth-2-Channel-Bookshelf/dp/B01KGPEW70
Thonet and Vander Kürbis Bt - 5.5" aramid fiber woofer, 1" silk tweeter https://www.amazon.com/Thonet-Vander-Bluetooth-Integrated-Amplifier/dp
Klipsch R-15PM - 1" aluminum diaphragm compression driver mated to 90° x 90° square Tractrix Horn and 5.25" copper spun magnetically shielded IMG woofer. https://www.amazon.com/Klipsch-R-15PM-Powered-Monitor-Black/dp/B01A7J534G
Also looking for a good powered sub for around $100-$200 max. Are any of these good? If not, open to suggestions....really, if there is a comparable pair of speakers AND amp I can get for $300 max, I guess I'd consider getting some real speakers and an amp if powered speakers really are bad.
