Subwoofer recommendation and wisdom

So I have a relatively difficult room 19' x 19' x 9'. I have made a bunch of sound absorbing panels which made a massive improvement. I have worked on speaker placement and landed on the 5/8 ratio......5x from the back wall, 8x from the side walls. I use Harbeth 30.1 speakers on appropriate stands, driven by a Luxman L505 xII integrated. I am very pleased with the sound but sometimes wish I had a bit more foundation on the bottom end. I will listen mostly to classic rock and jazz. I would like to consider adding a sub, but not sure where to start. I don't want sledgehammer bass, I just want a nice, blended bottom end on my music. I think that is one of the only improvements I can reasonably and cost effectively make. Looking for recommendations on a sealed sub that would have a good chance of integrating well in my room.

My preference would be for a single sub solution. Thanks

…oh, scratch that. I was looking at deep_333’s diagram and misread your room dimensions…

Buy used dual carbon specials and be settled for life. Performance across both low and high dB ends is truly amazing.

As others have said, two or more subs is preferred.  When my sub went bad and had it repaired, my dealer said I would likely be better off without it.  When I got it back it turns out he was right.  Multiple subs will cancel the room nodes which will improve your mids as well.  I currently have 4 subs with DSP and the sound is amazing.  Consider the "swarm" by audiokinesis.  4 smaller subs which will fix the bass nodes and improve your overall sound.  The price is reasonable and the service excellent.

To the OP. If your source is vinyl, go for a sub like my Martin Logan " Depth i. The opposing driver configuration, cancels out vibration.

I employ the swarm from Audiokinesis/James Romeyn.

The waterfalls below reveal the impressive degree of modal reduction, also known as ringing. There are valleys where once there were mountains.The bass extension is a nice bonus but the main gain is the acoustic benefit, since most high end subs can go as low. While I have a dedicated room now, their prior presence in the living room did not upset my wife because I could hide two behind furniture and the other two served as pedestals.
