Rel and Rhythmik are great suggestions. Whatever you do I’d highly recommend getting a pair of subs. On the cheaper end you could get a pair of SVS SB1000 (non Pro) subs from their Outlet for only $900. They’re only about 13” square but will still get you down to an honest 20Hz (-3dB), and they offer a 45-day risk-free trial including shipping both ways so you can see if they work for you. Hope this helps, and best of luck.

Recommendation for sub with high level inputs
Looking to add sub to existing system. Yamaha Aventage A6A powering center (Sonus Faber Sonetto ii) , wall height (Infinity Primus P362) , and surround (B&W DM 602), with Rotel Ra1592 integrated preout connected to power fronts (Sonus Faber Sonetto V).
I listen to (stream) 2 channel music 65 -70 % of the time - Roon with the hi-fi Rose 250 as my endpoint.
No regrets with the purchase of Sonetto V's, but after having them for a year now, I would like more low end.
I do not want to connect the sub to the yamaha, thus needing a recommendation for a sub with high level inputs to connect to my Rotel integrated which doesn't have a sub output.
2k budget?
Thanks in advance for your suggestions.
