This is a Roth Audioblob 2 sub-woofer (https://www.goodgearguide.com.au/review/roth/audio_blob_2/218039/). It contains a 2.1 amplifier, so it can power two external full-range speakers as well as the internal sub-woofer. It's a little bashed about, but works perfectly.
Let me know what use you can make of it and when you can collect. Please don't just ask "Is this still available?".
IMPORTANT: Please only reply if you have read this listing and looked at the photos. I reserve the right not to respond if you have clearly not done so.
