As follows is my current list judged from both experience and being an active participant/reader on this forum. Of course there are alternates to each of these that I'd also recommend in a particular pricepoint - in some cases the winner could even be decided by a coin flip because the subs are so close in performance, but generally speaking these would be my 'go to' recommendation at a given pricepoint for the typical situation.
Subs in red designate models I've heard in person.
Pricepoint / Recommendation
$100 - Polk Audio PSW10
$200 - BIC F12
$300 - BIC PL-200
$400 - PA-150
$500 - Rythmik's intro subs
$600 - Outlaw's upper tier subs
$700 - N/A
$800 - N/A
$1,000- HSU VTF-15H MK2 (I've only experienced the original - but MK2 is a very worthy improvement by the specs)
$1,333 - Rythmik FV15 HP
- top shelf sound quality --- the only thing you get above this pricepoint is additional SPL and matching sound quality in my opinion. This is the first 'level' sub of my list that I could say that with subjectively. With the higher priced subs -- you are getting that same sound quality with more SPL capability.
$1,666 - N/A
$2,000 - JTR Captivator (passive) + iNuke DSP 3000 amp
- Tremendous output, lots of air movement. Fantastic sound quality, A top shelf sub all around. Usually placed first or second at every subwoofer shootout it has participated in.
$2,500 - Seaton Submersive HP
- More output than Rythmik FV15HP - same sound quality! Wins the majority of subwoofer events it participates in. Perhaps one of the, if not the, defining Internet Direct subwoofer.
$3,000 - JTR Orbit Shifter
- Prodigious output. If a 30 foot robot was stomping through your neighborhood it likely wouldn't have the impact the Orbit Shifter can muster. A pair of these subwoofers can actually physically break electronics with their acoustic energy. A pair in the 2012 blind meet broke my projector convergence, my PC's bluray drive, my HD-DVD drive, cracked my kitchen floor grout (above my theater room) and loosed my drywall. Crank these beasts to max at your own peril.
Price no object? - to my experience there isn't much value in spending more than $3000 on a subwoofer...I've not yet heard a more impressive SPL demo than a pair of Orbit Shifters at full tilt. They made the hair all over you body stand on end, the jelly in your eyes shake, they very nearly felt as though they could control your breathing. We are talking competition car audio levels -- in your HOUSE. Yes, the kind of SPL levels that quicken your heartrate to dangerous levels and invoke the fight or flight reflex.
As an alternative; you sure can do a lot these days with DIY these days if you can assemble a flat pack.
$200 range - Stereo Integrity 18 HT
$250 range - Dayton Audio Ultimax 18"
$500 range - iST Ltd. UXL-18"
$1000 range - LMS 5400 18" or Stereo Integrity HS 24"
Amps like the iNuke DSP 1000, 3000, 6000 are stellar inexpensive options with built in fully featured digital signal processing including parametric EQs, dynamic EQs, voltage limiting, HPF and LPF functions.
Frequency response tools like REW or Omnimic allow for proper integration and setup with both DIY and Internet Direct subwoofer purchase/integration.
If you want to take the time to, buy/learn the measuring tools, and learn how to set these up, you can make a comparable system for 1/2 the cost of ID with AIY. If you don't buy the measuring tools and learn how to implement PEQs as appropriate for your build in your room - you might as well buy ID - you'll be more satisfied with that experience.
I currently have eight assemble it yourself, (AIY) subwoofers. I used the Dayton Audio UM18-22 18" driver with cabinets built by a shop in Chicago. I'm using Behringer iNuke DSP 6000 amps to power the subs. My project is chronicled here:
Bought four sealed 18" cabinets on a wild hare - Direct me to a driver setup at least competitive or superior to JTR Captivators...
You can see a frequency response capture of my system below. I'm reasonably flat to 7hz with my AIY system.
As to my subwoofer experience:
• Eight, Ultimax UM18-22 subwoofers in 21" cubed wooden veneer boxes. This is the best subwoofer system I've owned - when taken as a whole system. Individually just a sealed 18" subwoofer is not terribly exciting. When eight of them are combined, and a couple are nearfield, they deliver a remarkable presentation. Link to build thread: Bought four sealed 18" cabinets on a wild hare - Direct me to a driver setup at least competitive or superior to JTR Captivators...
• Jamo 650 sub - (purchased 2012) discontinued price of $250
. This Jamo is excellent for a smaller room full audible bandwith sub system (flat down to 20hz in room)
• Pioneer SW-8 = junk but still currently own for secondary system (purchased in 2012)
• Captivator Pro pair (purchased mid 2011 -sold in 2014) Love - all around my favorite single sub I've encountered when considering value to performance. A pair for 3k and 99.9% of the audio enthusiasts group is wholly satisfied)
• SVS PB13 Ultra pair (purchased mid 2011) (sold 2011 - I didn't like them for music, but they did great in home theater!)
• Yamaha CW218V (purchased mid 2011) (sold 2011 - love for music - doesn't do much for home theater)
• Jamo D7sub pair (purchased mid 2011) (sold 2012 - liked them quite a bit for $500 price - were fantastic for music with the right settings - THX Ultra II certified - overpriced MSRP - not very capable of high SPL)
• Infinity HPS-1000 pair (purchased 2003) (very nice subs IMO, the best Infinity has ever made according to my local authorized repair shop, one 15" driver with two passive 15" radiators and a 1000 watt amp - sold 2014)
• DIY subwoofer ottoman with four 15" MA car audio subwoofers (built in 2002 - sold 2012)
• JBL PSW-D115 - 15" home theater sub (purchased 1999 - sold?)
• AIWA HTIB sub = junk (bought in 1997 - sold 1999)
• Multiple iterations of car audio subs, some I used in theater (most of my car audio stuff was in my younger days - high school/collge -- my favorite car audio drivers remain the Infinity Kappa Perfect drivers)

~ and probably more I'm forgetting ATM.
and not so recently - - - scads of car audio subs --- up to some of the best types of subs like JL w7's and competition Orion drivers -- because I and many of my friends were into car audio.
My experience with subs that I would subjectively define as being able to pressurize a room?
My thoughts on the importance of subsonic ultra low frequencies?
Advice ; goal is 8-10hz flat at -15 reference

I've heard lots of speakers, everything from pairs of speakers costing upwards of $20k for a set, to the cheaper Internet Direct huckleberries touted heavily on this forum. Some of my favorites were not the ones that were most expensive necessarily. Read the links above to see my subjective evaluations on a lot of the various gear heard.
