Need advice on adding subs

I’m looking for advice on adding subs to my system.

I listen primarily to small combo jazz and classical but I’m disappointed by the classical symphonic reproduction. I can only enjoy symphonic music on my headphones. Perhaps, I could improve symphonic on my main system by adding subs.

I don’t listen at high volume nor am I a bass fanatic. I just want the better sound. This is strictly 2 channel system. I have no interest in HT. I live in an apartment.

My system:

Balanced Power Technology BP-1 Conditioner
Toshiba lap top with JRiver feeding via crossover Ethernet to
Sonore Rendu
Wyred4Sound Dac-2
Warpspeed Optical Attenuator
First Watt J2 Output power 8 ohms30 watts 4 ohms15 watts

Reference DeCapo MM 2-way Monitors

The speakers are a simple 1st order high pass passive 3kHz x-over to the tweeter. I believe the woofer is designed to rolloff naturally at both ends of its band width.

I’m open to any ideas. Lets say up to $2000 budget.

Oh, one (I promise ;-) other thing. The Rythmik Sub is what speaker builder Jim Salk builds in to some of his models. He also offers the Rythmik Sub in his own designed and built enclosure, featuring greater internal volume (for increased efficiency) and more robust bracing (for more non-resonant sound). His finishes are beautiful real wood, much nicer than the Rythmiks (except the Piano Black Rythmik whart got---it's real nice).

My advice! Velodyne optimum series! Why!! Built in room equalizer! Volume control for leveling and blending with your system! Subs are for depth and warmth! Not to rattle Windows! If 250 hzto 20hz doesn't sound like it eminates from your other speakers, your towers, it's just not high end reproduction! Subs should be adjusted to room acoustics and blending volume! My system is krell, Bryston, Psb imagine t3 speakers! Velodyne optimum 12! Total system investment, just short of 60k! Velodyne optimum 12, around 1300.00 ! Rel the best! Rel not volume controlled ! Rel at 2300 to 2500!

Cjk5933: Pennsy here! Read my posts! My sub advice came directly from two techs at Krell electronics! If you are a higher flier than my 60k system and 5 figure electronic units, well i understand!

My B&W 803's really opened up in my main room (25x235, most of my house). Since I had experimented with various woofers for my prior electrostatics, I had a baseline.
Instead of a generic sub amp, I use a matching amp and preamp for my subs. This is not necessary, but does allow me to place the sub cabinets in a time aligned fashion with my mains. It also allows a separate volume control with no crossover issues, because, I use a mechanical, rather than an electronic crossover, many of which I still have. It consists of foam in the center of the speaker cover cloth and beat crossovers designed for my drivers, as well as Thiel sub crossover I still have., and several others which as good but not as good as my reversed cone of foam. 
    On most LP's, FM, some CDs and especially XM, it really helps fill out the sound.
Th  sub system is off for most small combos.
