More Power or use subwoofer to boost bass for music


Hi,   just want to know if anyone can offer their opinions on how to boost the bass when listening to 2 channel music.

I just got a pair of B&W 804 D3 and would like to get more bass out of the speakers.   I remember the bass was pretty punchy when I heard it in the dealer showroom, but I don't seem to get that in my setup.   I currently have Parasound A31 power amp with 250 watts per channel.

So the question is whether I should get a more power amp, or add subwoofer to my 2 channel music.  I'm a little bit of a purist and would prefer not to use a subwoofer for music, but I'm open to this option.

I would definitely appreciate if anyone can share their experience/opinion.   Thanks very much.

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

"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.

They do not need to be the same.

Or, as my experience and measurements have shown, you treat the room with some decent bass traps and wall coverings to ensure the treble/bass balance is correct but no.... that's too much ....???
@erik_squires I used to think that way too. Then I encountered the Swarm, and in looking into the theory behind it, realized that its the elegant approach to a vexing problem- reliably getting the bass right in nearly any room.


Duke didn't invent the idea- and he would be the first to tell you usually, but in this case I beat him to the punch. It comes from a guy pretty well known in audio engineering circles; Dr. Floyd Toole.


So this isn't a cult thing- its just that its an idea whose time has come, and all that's happening here is you've not read up on it. So I suggest you read or look at some of Dr. Toole's talks on YouTube. Here's a good place to start:

Now this link doesn't say anything about a DBA, but it does very successfully show how the bass is so important in the way a speaker presents itself. Take the time to play the whole thing (the intro is done at about 4 minutes).


In a nutshell, you put Dr. Toole down at your own peril. He's one of the top engineers in his field. So- when someone is complaining about bass, no, you don't treat a room with traps because it literally doesn't work- although prior to running a DBA you might think it does. Its not a cult, its science. Don't be that guy who contributes to the death of science- look at how Dr. Toole developed this.
