More Power or use subwoofer to boost bass for music

Hey @audiokinesis thanks a lot for your suggestion, and also everyone else for such a colorful discussion.   :-)  

There are a lot of good information here.  One thing for sure though is I don't have the space for 4+ subs.    I definitely have space for one sub.  That is to replace my old one that I only use for movie right now.   It's sitting in the corner of my room, but partially obstructed by piece of furniture about 1 foot in front of it.   So the location is not ideal.   It will be a challenge for me to try to fit a 2nd sub in the room.   BTW, my speakers are already very close to the back wall - right around 1 foot away.    So technically, I'm already placing my speakers at a good location from the bass perspective.

Anyway,  I think I might give a new sub with EQ a try, and get myself out of this 'purist' mode :-).   Will also do some research on room treatment.   

Actually I might start with a new dedicated stereo preamp for my 2 channel music and work from there.   

There are definitely a lot of moving parts in this hobby, and a lot of trial and error to pursue the best sound.  But it's all fun stuff.  :-) 

Well unless someone here is interested in a professionally designed sound system, complete with 3D modelling of the acoustic field based on architectural drawings, industry measured material properties, and sufficient speaker models or they are trying to design tolerable audio into the latest miniscule consumer gadget and need to design and model the acoustic performance before finalizing the design and committing to tooling, or they need help with designing and implementing psychoacoustic experiments, or, and this would be unlikely, they need a device for medical or industrial "sonic" treatment (or measurement) then yes, I would be guilty about my motives. This is not the case, here.

The swarm was an interesting idea which is promoted by fetishists whose motives and honesty I question.

The truth is many modest systems achieved great bass with proper speaker placement, modest acoustics, and soemtimes a sub with an EQ long before the swarm and there will still be systems with great bass long after the swarm.

To hear the fanatics tell it, no one has even heard bass before them, and only they can fix it. Also, only they know about room acoustics. It's magic. Ignore all the previous work that has gone before, because it's bunk before the swarm.

thanks for that @audiokinesis
Duke..when using 2 subs with floor standers, do they need to be identical or can they be close models...Could i use a REL S/3 with my REL S/5 ? thanks...I also have no room for 4

heaudio123"No "sunshine", all the numbers show is that it can deliver 350 watts approx into 4 ohms with 1% distortion. Those numbers do not show output impedance which is what would actually jmpact frequency response"

As has already been sufficiently, properly, and correctly explained you are once again completely wrong even though you are partly correct but being partly correct is not fully correct. Output impedance is only one factor in this equation which you have sought to oversimplify by overlooking others factors as has been duly noted to you hear by others you’re pretending to be some kind of electronics/audio/acoustics "expert" suggests based on you’re own summation that you "perhaps" once worked for Radio Shack and are now qualified to call your self a "conskltant" even though you have such incomplete understanding of basic, rudimentary, fundamental elements involving audio and Music Reproduction Systems.
