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.

I already had made an argument for them. However in an apartment a bass array has far more chance of a successful implementation and likely less obtrusive.

Uh huh..... yeah, we have nothing at all but space in an apartment, space and money for 4 subs, and the wiring.... yeah, lots of that.

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 ....???


Hahahha.  Cult.

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.

Please mark me down as some one who no longer believes those people are well meaning.  I'll no longer bother arguing with anyone of that ilk. You have convinced me of your intension$$$$$$$$$$$$.

For the record, NOBODY here has a financial interest in the Swarm except for me.

Erik if you feel that the main fetishist behind the Swarm needs to have his motives and honesty questioned, I’d like to hear you out.

Xcool, I apologize for entering your thread to squabble with someone. Erik and I are not enemies (far as I know), but we do have differences of opinion on some subjects (that NEVER happens among audiophiles, right??). Imo bass traps (absorbers) are not the solution when you’re trying to increase the net in-room bass energy, but I am absolutely a fan of GIK Acoustics.

Anyway let me try to offer some thoughts about your bass situation, taking into account that four small subs probably isn’t feasible:

Your B&W’s gently roll off by about 4 dB per octave from 100 Hz down to 30 Hz before boundary reinforcement according to Stereophile’s measurements, with the rolloff accelerating rapidly below 30 Hz. In rooms with generous boundary reinforcement, this can give bass extension down to 30 Hz ballpark.

Presumably your room does not provide generous boundary reinforcement at your listening position with the speaker positioning you have. Just for fun, you might try standing at the wall in the back of the room to see how the bass sounds there.

You asked about amp or sub. I am inclined to think that sub(s) will make a bigger difference, and a more fine-tuneable one. I was a Parasound dealer for many years and think your B&W’s are well within your amp’s comfort zone.

You might consider this: Adding two smallish subs, one along a side wall (but not centered), and another along the rear wall (again, not centered). Considering your B&W’s to be bass sources down to 30 Hz, this would give you four in-room bass sources, with two of them (your B&W’s) symmetrical with respect to one another, and the other two asymmetrically placed. I can explain why this might be beneficial if you would like.

I see now that this suggestion is pretty much a repeat of heaudio123’s post above. Nice job, heaudio123.

Xcool, best of luck with your quest.
