My personal opinion: If my music source consisted mainly of spinning analog records on a turntable, say around 90% more or less, I wouldn't even bother with subwoofers.
Subs, IMO, are a digital thing. ...CDs and Blu-rays. It's easier to implement them digitally with FIR and IIR filters from 1Hz to 250Hz, and the crossovers and their slopes.
Analog, me I prefer stay analog all the way ... 20Hz to 20kHz. ...Even 27Hz I'm happy music wise.
And my hearing on the top octaves is shut above around 13Hz.
If I was sixteen and my music source was a turntable, I'd be happy with speakers that can do from 30Hz to 16kHz ... sez. ...Good on and off axis.
It's a nice day today on this April 1st, 2019. It's great to be alive and see all that spring coming alive too. ...Plants, flowers, birds, trees, ....
