Odd subwoofer question.

I am not a sub woofer guy. Have played around with a few. Both high end and mid level. They never did much for my primary system (Aerial Acoustics 7B towers, AR tube pre, Levinson amp). But, I don’t really know anything about subs or how to optimize them.

Anyway, in my living room my secondary system for casual listening consists of a pair of inherited Aerial Acoustics 6T towers driven by a Sonos Amp. I know. Long story. But in truth the Sonos Amp does a really good job and ties the 6Ts into the house system.

I’d say 75% of the time I am totally happy with how this system sounds. At times I’m amazed how good it sounds. But, sometimes I do wonder if a sub would add anything.

My audio fetish is tight, precise bass.

I’m looking for advice on a sub woofer to try. Given the nature of this system I am not looking for anything high end or complicated. But also wondering if a modestly priced sub is just going to muddy the waters. All advice appreciated.

The Sonos Amp does have sub output.

Thanks.
