Looking for subwoofer recommendations

As someone who owns an SVS sub, I’d prefer Rhythmic but they’re also a bit more expensive.  Do they come with integration software?

Thinking about a Rythmik sub. Seem to have a little edge up on the svs. Been watching some videos and they seem like a winner. 

White REL T5x over on usaudiomart for a few bucks less than retail. 

HSU ULS-15 Mk 2

I had a JL Audio 10" sealed sub that was extremely punchy- just a touch too much cabinet resonance that blurred the midrange at times.  

My favorite subs were REL T9i, sealed but with passive radiators.  Very fat, punchy and easy to integrate.  

Each were very musical and not special effects subs.  

Ultimately I got the punch I wanted with near full range speakers and a quality amplifier. 

That's exactly what I'm looking for, a sealed sub. 

Watching marketplace everyday for one. Seems to be a buyers market on used stereo equipment, just have yet to find what I'm looking for. Researching new ones as well. 

I recommend a sealed box design.  You get better control over the cone [surround] for quicker response and accuracy.

Wow, thank you for the suggestions everyone. I do have the svs app for my pb2000 pro. I can hear a difference when I change settings but it's not a huge difference. Hence thinking I should have bought the sealed sb1000 pro or sb 2000. Just feels like this sub would excel at movies but not music. To be honest I've gone down the surround sound rabbit hole and realized I prefer a 2.1 or 3.1 setup. Maybe if I had a different room I'd feel different. I'm kinda trying to go the musical route.

Raymundo75 asked a great question, I want realistic sounding yet clean sounding. I also like to add some punchy bass to many tracks. I don't care about rattling windows. I have a Adcom 7000 ruining my Cerwin vegas and Klipsch Synergy f30's with my Polk PSW12 when I want to decompress from work and music shake the entire house. Looking for the right partner ( s) for my B&W's for accurate yet full and powerful sounding music. Sometimes at high volumes. 

Playing around with a third system at the moment... Don't laugh it was free. A Qinpu A3 running my Klipsch kf26 towers. ( Read busy buy cheaply made)

It's amazing what 8.5 watts do with these speakers. 

Although it couldn't be my go to .

Thank you everyone for the suggestions, please keep them coming. I'm in the Flint, Michigan area, northeast and 20 mins. Not sure if anyone on here is close. 

My friend that passed away, his real name was George O. , Lived in Grand Blanc, mi. I want to say someone for this site came out for some installation for him. 

Considering additional info, add one sub on the floor like you said, and the other three different distances from the floor. Multiple subs asymmetrically located relative to corners is the key, and this includes ceilings. Might be hard for your average audiophile to put a sub 5 ft above the floor. Should be no problem for a master carpenter.

Get a REL T/9x. Its incredibly musical

The first question you need to answer is " do you want realistic sound reproduction or do you just want to rattle your windows" ?

[[baylinor   How would one connect a third sub if the first two are hooked up in stereo mode, one left, one right.]]

Most subwoofer inputs sum the left and right. Some have L/R and LEF outputs. Running the left and right outputs or left or right output would source the third sub.

I have the SB2000 Pro. Get the app! You can adjust Low Pass Filter, Phase, Polarity, Parametric EQ, Room Gain Compensation and of course the volume.

Agree with miller carbon, I have 3 subs (looking for #4) and I have it dialed in nicely....

+1 for a Vandersteen sub or two.

Using the external crossover makes it seamlessly integrate.

Yes, you will pay a bit more money, but not having to fiddle with settings (only set the crossover to your amp's impedance), makes it easy to set up.

Add to that, Vandy subs are built like tanks. Even 2w subs are still working to date, despite being 30 years old.

Aside-

I use a pair of Hsu Subs in my office. I would have put the 2wq's in, but space issues precluded that move. In any case, the Hsu subs are perform well, but not to the level that my 2wq's and Sub 3's do.

Economical custom length cable here.

This Vandersteen sub is a no brainer if you can figure out the crossover thing…

If not, you can get a SB1000 Pro from the SVS Outlet for $575 might work better in your room and still get down to 20Hz (-3dB).  Best of luck.  
 

Room size is described in my original post. It's basically L shaped, which is far from ideal but it's what I've got. 38'x19' with a 12x9 corner of it walled off  into a bedroom. I'm left with about 625 SQ ft. Not a lot of options for sub placement unless I go wireless. Previous owner drywalled the ceiling 🤦‍♂️ so getting wires across to place a sub anywhere but on the wall where all the equipment is located is pretty much out of the question. I'm a self employed master carpenter and builder. I won't drywall a basement ceiling even building for a customer. A nice heavy, acoustical drop ceiling is the way to go. Endless possibilities to run wires, etc. 

Keep your eyes open for good pricing on used REL subs. Knowing the size of your listening room would be helpful.

I've had good luck with three subs. I learned a lot from MC's post, here. My room was good with two Rythmik and one Rel. People have compared those here. Two subs wasn't enough. The third sub was the charm, positioned out near the listener chair.

If you mapped your room after the Crawl try locating the PB near the second loudest room mode and shop for an SB and locate it in the loudest room mode. 

Take care they are asymmetrical to each other and possibly facing in different directions. 

I don't see application adjustment suggestions when using both PB and SB. Contact SVS for advise assistance. 

When I added a second DSP sub the relocation and addition noticeably changed the rooms loading requiring far less output from both units. Mine are optimized individually to memory presets then run as master and slave. SVS may suggest a different approach. Your more than half way there.      

2 x REL T-Zero Mk3. Two will enhance your stereo space and load the room more evenly. These are small and effective. Wire from the speaker terminals.

My recommendation is four. 

I've done the subwoofer crawl, had SVS send me the port plugs and tuned it on the app. It digs very deep which is good but it's leaving in the punch area. More of a home theater sub I think. 

I’m wondering if that SVS sub could be adjusted and/or placed in way that you’re satisfied with. Placement and adjustments are critical. I suspect that many folks set the gain and the crossover frequency too high. A sub should augment the existing bass, not be featured. It should only be audible on the lowest and loudest bass passages.

You could also experiment with stuffing the port.
