A pair of 10" passive "true" subwoofers responding musical signals down to 16Hz. I am the original owner and overall in very good condition with no issues with woofers and surrounds. Only used them to support a pair of Maggies over the years and never driven to bottom out.
No boxes but do have the original manual and passive crossover to be connected to your main amp's speaker terminals and input your subwoofer power amps.
These subwoofers are made for music purpose and I wouldn't recommend them for HT use. You can power them with 40W - 300w per channel modest power amps. 40W power would deliver 109dB down to 20Hz.
Unfortunately, I can't ship them and prefer local pickup in Seattle area.
Thanks,
