Have your ears checked first after Q-tipping; hydrogen peroxide flushing is a cheap homebrew means as a second follow-up. Age effects the ears of all, despite claims to the perfection of one’s hearing.
Putter about with some room treatments....usually ignored, but can yield some great improvements without resorting to finding your closest rabbit hole to dive into.
If you plan to reno the room anyway, get that behind you prior to any major treatments. Any treatments prior to run the risk of being ill-advised or just plain wrong and a waste of $’s and time...
Get a sub sized for the space and note if there’s still issues.
If you like what you’ve already have, it’s a good exercise to improve upon what’s at hand before taking the dive into one’s chosen ’upgrade’ options.....
At that junction, the only sound that sucks will come from the $’s passing through your wallet or cards..... ;)
