As a proud L12 owner, I am sure that you will love it. However, I don't believe it has speaker level connections, line-level input only:
I was going by this:
Looks like speaker input is below the controls?

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.
Velodyne has fallen far off. It's a shame , they where my favorite sub company back in the day. They build some of the very best subs on the market.
Today JL Audio took their place in the market and they are equally as good on many levels.

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…
I gotta agree with this. Martin Logan Exploded onto the Sub scene back in 2001 or so. They knocked it out of the part with ease. We all where shocked in all the models they released and how damn good they all where.
If you can grab one, get one they are remarkable.Dan

New prices of everything has gone up. SVS has a 1000 series Pro sub that is supposed to be wonderful especially for the money. It's $599 retail so if you can put together another $100 , I think you can get a really nice affordable long lasting subwoofer.Dan

Bob, different plate amps go to different models of subs they offer. The plate amp pictured below is available on the F-25 (and possibly others) as an option.
The above photo is just a photo of how direct servo works, not the plate amp that comes with the sub you ordered. Drew provided a photo of the "actual" plate amp that comes with your sub. When I looked, your sub model appears to not be available with speaker level connectors.

Y splitters on a line level connection will bypass this issue but from the looks of it, your sub is not offered in a speaker level connection.

Introduced in 1968 the Infinity Servo-Static speaker system introduced the first servo controlled subwoofer designed by John Ulrick.

Crap. Hope I can cancel the wire order placed yesterday. Attached is the description of the inputs/outputs on my preamp. I would be using the EQ jacks?

You can get a "Y" splitter and just split the signal coming out of the main outputs. One would go to the sub and the other would go to the amplifier.

Your preamp has two sets of RCA outputs, so you're golden as long as you have another set of RCA cables handy.
Simply keep the first set running to your amp and run the second set to the sub. You can cancel your speaker wire order.

But, I'm currently running two amps from those outputs. A set of outdoor and a set of indoor speakers.Yep, my name really is Bob.

Hey Bob, another possibility is RCA splitters, which I have used for similar situations in the past I have a nice pair of Audioquest that I am no longer using if you’re interested.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

Two of these on the main output should get you what you need.

Yes, I have some Audioquest branded splitters like that that I am not using…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

Keep in mind the second set of preouts is already a splitter so using another splitter could cause some issues- Not Tom ::::::: Any system can play Diana Krall. Only the best can play Limp Bizkit.

Now that I think about it, rarely run both indoor and outdoor speakers at the same time. I guess I could use the 2nd preamp out for the sub if I deisconnect the outdoor amp from the preamp. A bit of a PITA, although really not have to be done very often, but maybe a better idea than splitters?Yep, my name really is Bob.

So, with cables at 22-25' I know capacitance is something to consider. Not sure how to compare these 2 specs:
Nominal Capacitance: 39 pF/meter @ 1kHz and 17 pF/ft
The former is a SVS cable and the latter is a Beldin.Yep, my name really is Bob.

@muncybob - both of those capacitance figure are LOW, which is great for long runs.
Generally, I think runs less than 50ft. are considered short cable runs. You should be ok. Just go with the Belden, imo, unless you want a tad more bling from the SVS.CD Players: Sony CDP-211; Sony DVP-S9000ES; Sony UDP-X800M2 (x2); Cambridge Audio CXC

Just informed, sub delivery is delayed until 11/24....damn!
Really looking forward to how it plays with the SDAs and I want to also put the Vandersteens into the mix, as they are a little light in that area.Yep, my name really is Bob.

Ah, that bites. When I got mine, they were stuck out on a ship out at sea off of Galveston TX for an additional 4 days. This was way before the shipping delays of today. The anticipation, I remember well. What put me at ease was one of my favorite sayings...

Martin Logan Grotto for $575 local to me. Decent price?

The sub came a day early, had some fun last night. I think I have some more tweaking to do, but it sounds pretty good to us. Even my wife who has very little interest in sound quality said the system sounds "clearer". I must admit, that was my 1st impression too and was not something I was expecting to hear.
Using Rythmik's suggested default settings for 2 channel, I thought the lower registers were overstated....too much bass but still not what I would call boomy. The crossover setting really makes a big difference. With the SDA 2Bs I find the crossover around 50hz sounds best so far, but like I said there, is more tweaking to be done.
The sub is a silver lining in what is to be bummer of a holiday for us as the Mrs. tested positive for Covid yesterday. No trip to my daughters for turkey
More time to listen to music I guess. Yep, my name really is Bob.
