I actually work in Audio Engineering. Bit of trivia when looking at subwoofers. Most movies are mixed to a reference level of 83 db. This is from the reference standard Dolby's Ioan Allen proposed back in the 1970's
Genelec's are actually used in a TON of movie mixing rooms in the pro audio world. So those movies you watch actually had their soundtracks done on Genelecs. Movie Studios using Genelec include Sony Pictures, Pixar, LucasFilm etc... They are also used in the monitoring booth for the Grammy's.
The Genelec's have the 5.1 Bass Management built in. I recently installed a Genelec 8030 5.1 with 7060 sub set up for a business in a room that was 20K cubic feet. You can hear the system going from 70 feet away with the door open. It isn't setup for movie watching but it puts out enough bass for a room 10 times the suggested size. And that isn't even pushing it. If you are anywhere close to Michigan I'd be happy to let you check out the system. I have the 8020, 8030, 8240 monitors and the 7050 Also you can get a Genelec 6010 5.1 Setup for around $2495 and a 8020 5.1 setup for $3895 including subwoofers. I must stress audition the speakers in your own home. That is the only way to evaluate a speaker set up.
Sweetwater has those genelec 5.1 setups and also might I mention their return policy is great for home theater.

Here are the links to those prices. Now bear in mind they don't charge tax on you.... OR Shipping... So these are the set prices you'd pay. End of story out the door. (No I don't work for them)Genelec 6010 5.1
$2495 35 hz subwoofer output. Note: The Genelec 6010 Series uses RCA connections.Genelec 8020 5.1
$3895 25 hz subwoofer output.
You can also do a 7060 Sub with 5 Genelec 8020's from sweetwater for $5194 19 hz subwoofer output.
If the 19 Hz is a hard sticking point.
You can also do a 7060 Sub with 5 Genelec 6010's from sweetwater for $4349 19 hz subwoofer output.
You can even do a 6.1 setup with a 7060 Sub with 6 Genelec 6010's from sweetwater for $4699 19 hz subwoofer output.
For Audio Critical Theater installs the 6010 is rated for rooms of up to 2000 cubic feet. As is the 5040A subwoofer.
GSNR: As for a reference mastering movie suite quality audio card to run your setup. I'd suggest a LynxTWO-B. It offers 6 channels of analog output. They can be found easily online for $899 and lynx converters are used in movie and music rooms worldwide.
Also if you ever want to sell them. A pro audio speaker is going to hold it's value consistently compared to most home audio speakers which are the equivalent of cars as you drive them off the lot!
Frankly, if it were me I'd go for the following setups and my logic.
Genelec 8020 5.1 for $3895 if you can give up the extra six hertz. The bottom A key of a piano is 27.5 hz and a 7050 Sub goes to 25 so all music material is covered. (rare exception for classical piano using a bosendorfer piano or lowest notes of organs and tubas. But these are well below the threshold of human hearing. All they will do is reinforce harmonics in frequencies above that.
7060 Sub with 5 Genelec 6010's from sweetwater for $4349 will get you your 19 hz and be under the price you wanted to be for speakers alone.
And hitting your 19hz requirement and the $4700 cap for speakers. You can do the 6.1 Genelec setup with a 7060 Sub with 6 Genelec 6010's from sweetwater for $4699
I'd spend any savings you had on sub and speakers and treat your room. Your room is highly reflective and boxy. That will make any system you go with sound worse than it is. Genelecs will sound good in an untreated room. I've installed them in a bowling alley before! Acoustically what you are going to get from the Genelecs is a more comprehensive enveloping sound field that you won't get with a more directional speaker like a Focal or Adam. I've use all three of the brands over the last 15 yrs. Focal is a recent entry into the pro audio sector so they've not gotten as much penetration as Genelec has since the 1970's. They are excellent speakers and I'd rank them above adams, The adam's uses a ribbon tweeter which is a bit more harsh to some in it's upper frequencies. Focal is a beautiful speaker maker but their pro line is the only one I'd consider because they overprice their home line for the same tech found in their pro line.
