Subwoofer suggestions for budget system?

I should add: the labels on the back of the Klipsch are not possible to read. Who designed it? I took pictures of it with my phone and DSRL and still cannot read the numbers 

what type of music do you listen to that you are missing the low frequencies for?

I am in the same boat - low budget, considering a sub - but I am not sure it would make a significant difference for me

@hilde45 shipping for a 12" sub with UPS ground anywhere in the lower 48 < $40. Not worth driving around for hours

@jl45 I just shipped a giant Yamaha subwoofer for $45 to the opposite corner of the country, 3-5 business day.

"Any subwoofer is better than no subwoofer. "

I am on the fence about starting a post with this. Is this true, always? Do I need a sub? If I mostly listen to music with little low frequencies (I think?) in a small room,

What are the rules for having to have a sub (or 2)? Why 2?

@m-db, @soix 

so my SVS SB-1000 arrived and so far it sounds terrible (worse than that). It's possible my room will never accommodate a sub. But I am not done playing with the placement and settings. It is also true that the music I listen to is mostly mid and high range of frequencies.  I understand the 2 subs argument but I have neither the space nor the budget. Not only that, my path to get there would lead to first one sub and if I am unhappy with one, I don't feel I would have the urge that I must have one more! :)

Thanks for your insight and advice, guys like you make this a great forum!

@soix I did what the manual said. It sounds better. Still reading up on it and tweaking. Maybe there is no chemistry between Dynaudio and SVS :) 

@soix 

thanks! I started the crawl and I found it to be best between the standmount speakers, by the back wall. I don't think anything is wrong with the sub. I tried a longer cable to move it to the sidewall and it was very muted. My better RCA cables are 6 feet and I am wary of using barrel connectors. On the "plus" side, my CFO told me not to get attached to it, I only got approval for trying it out and returning it :)
I am browsing used ads, I think a smaller, older unit could get the job done.

and it does sound better, especially at lower volumes, like under 80db

@m-db - I set it up according to the quick manual and no I did not map my room nodes - yet, more to learn for me.

I keep the crossover low (50-ish) since the Dyna's claim 40Hz–23kHz
I need to figure out if the phase change helps, if only my CFO would do the nob turning for me :)
I'd say the best part is, when the SVS works right, the 3D effect really kicks in. I am all about vocals so my main concern is to keep it bright, forward as if the singer was right in front of me, not behind the drums and I sense that deep bass can swallow the room easily

so I just listened to Bohemian Rhapsody and I was like: wow, it's finally come together. And then I noticed the sub wasn't on. Baby steps....

@soix so I was confused about the SVS, and went out and picked up a Klipsch Reference R-120SW sub and I am glad I did. It’s a much bigger box and sounds profoundly different. If the SVS is a bobcat, the Klipsch is a lion. It makes the room feel much bigger. However it’s very raw, aggressive, a bit tiring. I feel like I was in a DISCO for an hour and I just spent 20 minutes with it, my head is buzzing. So the ideal solution must be somewhere in between. (And I am still not a Klipsch fan but I appreciate the scale)

It feels like it’s absolutely possible to live without a sub but may not be worth all that much without it :)

thanks @soix I will look for a used Vandersteen one. I think it's hard to pair Dynaudio speakers with subs (my lame excuse) as the Evokes are so relaxed, musical and warm.  

@m-db

yes I am dealing with a lot of limitations, making slow progress.... and it's not even my post :)

@soix 

I made some progress with the SVS. The Klipsch is just too hard to blend in, I never found the sweet spot. It's very possible that it's me not the sub, and it's just a lot more testing. It seems that there is no one setting, one place that fills the room correctly for every track and genre, maybe that's why people use 2?

@soix yes it definitely adds depth, almost like going from 2D to 3D and the dynamics of changing where instrument x comes from.

Sometimes it reverbs when it just should not, which must be phasing and location issue. Maybe my room is too small to make it work (my brain is too small to make it work:) )

I feel like I should try REL before I fully blame myself: REL T ZERO MK III

that's the last step indeed, using the speaker connections. I am a bit reluctant since the sub has a monster amp but still, there would not be any phasing issues. 

@soix I did, I took a little break, I am back to tweaking again. I just figured out that  phasing and placement go hand in hand (and then I read up on it and confirmed it) baby steps :)
