Not quite as much experience as you but I find things pretty much continue to get worse as you age so there's nothing to worry about. As toes and ears fall off, Crazy Glue works a treat. By the time your ninety, you'll lucky if you can see the steak in the meat case and there's a good chance you won't have to worry about being able to chew the delicacy so in the long run, it all balances out.
As to the subs, absolutely there's more to be had. As we age, from personal experience, pretty much, you know our hearing sucks and with the added benefit of today's internet direct (ID) subwoofers, relatively speaking, today's subwoofers will get the energy in the lower, harder to hear, octaves. This will make it "EASIER" for aging hearing to hear those hard to hear bass notes.
A recommendation for your ears, get a subwoofer with a fifteen inch driver as a fifteen inch driver has about twice the output of a twelve in driver; more bang for the buck. If you have a small enclosed room, go with a sealed sub, if dealing the vastness of a large room with lots of ancillary rooms and high ceilings, go with a vented subwoofer.
In the price point one would find a PB-1000, I'd look to a Rythmik, LV12R. Even with this recommendation I'd encourage you to consider subwoofers with fifteen inch drivers. Yes, a bit more expensive but definitely a match that will complement those aging ears.
FWIW, I'm sixty-one. Boo-Hoo me.
