If you want musical, definitely go with a direct servo sub. It doesn't matter which brand IME, what matters is that the sub is a direct servo sub. Trey pointed out a very solid choice that is just a little bit above your price point.
People who have direct servo subs tend to keep them or upgrade them, which is why they seldom come up on the used market...and for good reason. There is no "boom" at the bottom but they have no problem hitting the lower octaves with complete authority.
The ugliest sub I have ever seen in my life actually got me turned onto direct servo subs and I haven't heard one in all of my travels that sounds like a direct servo sub.....but you can damned sure tell when the sub is not one by the bloated or exaggerated bass.
I own two Rythmik subs and they don't break a sweat, no matter what I have thrown at them FWIW. I would highly recommend them but again, even if you don't go Rythmik, my advice would be to go direct servo. Your ears (and your neighbors) will thank you.

Good news, the boss has given me the green light to go to $600. Any other suggestions with that budget?Yep, my name really is Bob.

If you can find a used Martin Logan grotto, those are excellent. Original ML dynamos abound an eBay and are very musical, sealed, and hit into the upper 20s. You could get a pair at your budget. That’s what I would be tempted to do…Living Room 2.2: Usher BE-718 "tiny dancers"; Dual DIY Dayton audio RSS210HF-4 Subs with Dayton SPA-250 amps; Arcam SA30; Musical Fidelity A308; Sony UBP-x1000es

So I read this statement bout servo subs. Is it referring to the sub's amp or the main rig amp? One downside to servo subs is they need " enormous amount of amp power they demand to do their job"Yep, my name really is Bob.

It's referring to the sub's built in amplifier. All servo subs will be self-powered.

The Abyss is also good, but not servo.

Direct servo subs are unlike any other. It's not like you can go to Parts Express and build a proper direct servo sub. The plate amp and the driver act as one and are not interchangeable and from what I understand, they are built specific to a certain size/volume cabinet. Both the plate amp and the driver both have to be direct servo in order to work and they need to be engineered together, not separately.
In comparison, so long as you get a regular sub cabinet's internal volume correct? You can pair any plate amp with any driver depending on what you want (Just not a direct servo driver/amp). You just cut the hole(s) to size and install each one.
Mr. Gary Koh (the owner of Genesis https://genesisloudspeakers.com/ ) and I were talking a few years back about direct servo subs and I started inquiring about his. His are all direct servo subs, FWIW. As the conversation went on, he had mentioned this sub called a "Rythmik" sub and stated that one of these would give you 95% of what his could do at a small fraction of the price. Hmmm, "Rythmik, huh?"
At the time, I had never heard of them and what started the conversation was I got to talkin' about that ugly direct servo sub....and that it was hands down the ugliest sub I had ever seen but it was the easiest to dial in and the best sounding sub I had heard to date (at that time).
Anyhoo, I went and researched into Rythmik subs and the one thing I noticed is that you do not hardly see them come up on the used market at all. When they do (or did) come up for sale, folks were either downsizing and getting rid of their gear, they were upgrading to another Rythmik sub or......well, I don't recall at the moment any other reason why folks would sell them, so those may have been the only two reasons I came across when I was in the market.
So, I got in contact with the owner of Rythmik and ordered me 2 F-25's and they were delivered in time for an audio event where my system was featured at the time. They sounded incredible right out of the box and still do today. They are incredibly tight, yet very authoritative without breaking a sweat at the same time.

The F-25's have 800w plate amps on them IIRC. That's not that bad IMO.

Once you go Rythmik you never go back.

I was gonna agree with that but I don't think it's the company Rythmik that does the subs so good. I think it's the technology of what direct servo brings to the table. That ugly sub was made by Infinity and it was no slouch...at all.
That sub literally took 5 minutes to dial in and one of the most commented on aspect of the featured rig that year was how well the sub blended into the mains/room. Subs usually take much longer than that to get dialed in correctly and still have noticeable issues that present themselves from time to time. Most people didn't even know there was a sub until we told them. That's when you know you nailed it. This (the ugly sub) was paired up with a pair of Apogee Centaurus'.

I’m happy with the REL HT1003. Sealed sub, but not servo. Tight, fast, punchy, and well-delineated bass to my ears. I think it goes down to 25Hz and available for $600.CD Players: Sony CDP-211; Sony DVP-S9000ES; Sony UDP-X800M2 (x2); Cambridge Audio CXC

The original servo sub company is Velodyne, but unlike Rythmik, not all of their models utilize servo technology.
Going off memory, Velodyne servo subs sample the driver movement 16,000 times per second. Tight, tuneful bass is the result.
Velodyne set the bar for subs many moons ago. Over the years the owner, David Hall, lost interest and recently sold the company. Velodyne is now owned by a German business man, nice guy.Political Correctness'.........defined

The room is 15X26 with the listening area apprx. 12 ' from the speakers on the 15' wall. I'm hoping the sub placement will be about 10' from the "listening chair". I know it's hard to say without actually hearing it, but would you think the Rythmik 12" 300 watt sub do the job? I like the specs, reviews and the price.
Found a few used Velodyne servos but their amps are lower powered.Yep, my name really is Bob.

After careful consideration, we decided to get the B-stock Rythmik L12. Ordered it yesterday. The Mrs says it's an early Xmas present for me. Never had a sub in the 2 channel rig, so really looking forward to this!Yep, my name really is Bob.

Awesome! That will feel like a whole new system once you get it dialed in. Leaps and bounds upgrade, IMO.

Speakers are "upgraded" SDA 2Bs. They don't lack much in the bass area, with perhaps low volume listening, but you never know what you are missing until you try something, right?
