5 string bass will go down to 29Hz.
Synths same or lower.
Church organs 18Hz or so. You feel below 20Hz rather than hear it.
Most speaker manufacturers roll things off as discussed above, so as not to set rooms off with boom. One size fits all..
Best thing is to measure and use DSP correction or use of bass traps to absorb booms.
I actually have +5dB at 20 Hz to get that Toccata and Fugue in D experience.
Without room correction the room / system I have would be unworkable I think.
As it is, after much measuring and tweaking, it sounds all right.

Try the opening rumble and air movement in Sting's A Thousand Years here. If you don't hear/feel it, your bass is not in the subterranean response league.
No room correction for me, just big speakers!

Love Brand New Day
Time to put it on again to check out the bass

I keep my bass response flat in the eq settings

You are one person I know John who doesn't need any more bass!!

This is one album I haven't played since I took ownership of my wonderful Milburn MkII speakers. I've just put it on, and the bass is awesome, air shifting stuff. Ali, you're in for a treat  |

Brand New Day has become a different album - even better that it was before. Bass for sure along with loads more going on, more clarity. Boss is still out so volume is still high Brand New Day track now playing - wonderful. That bass line must be the man himself |

It's another great track, Mike.

Volume and frequency response are only previews of the whole picture; all else being equal you can have two speakers that measure the same in these areas but it tells you nothing of their resolution, speed, authority, tunefulness etc.
Broadening this statement, you can say it about any component.
I was explaining this to a friend who’s interested in audio but not to the same degree as me; measurements can be a useful indicator for limited aspects of sound and potentially matching components, but after that you have to trust your ears.

We don't yet have the kit to measure what is important. Will we ever ? Have to put up with the sticky out bits on the side of the head and the lump inside |

Agree entirely with using ears to determine SQ.
BUT that not the same as understanding room acoustics by measuring and doing something about it, where there's a problem.
You might try many, many different speakers in a room and find none of them perform!
Without measurement of bass where room acoustic problems are present you are shooting in the dark.
You might be lucky and find the first pair to your liking - typically these could be rolled off commercial ones and you'd never know what you are missing..

There's always room treatment as a passive counter to room correction.

Fly in room ointment
When we first moved in here the sound was horrid.
Convinced it was speakers or room.
Nope. I stupidly had the kit running off two cheap daisy chained four way adaptors from one switched socket.
Didn't help the outside earth was barely connected either.

Was it low res / grainy or lacking oomph? |

The best one I ever had was a >20 dB boost at 35hz! I say > because it went off of the graph so will have been a tad more.
I knew nothing about acoustics prior to this situation but just knew something wasn’t right (lol). Being a small flat, there was no room for acoustic treatments and so I discovered dsp; it went a long way to curing the issue.
I look forward to setting somewhere so I can treat the room in the physical realm first.

Was it low res / grainy or lacking oomph? All of that and more. Poor quality, through curtains. Everything was wrong Forgot I *previously had the kit on a dedicated spur all with their own unswitched sockets |

Ahem...of course, you could always choose speakers that use the room to their advantage, instead of trying to play music in spite of it.

Start with the smallest pair and figure there were no room modes as the bass was so limited and work up through floor standers, ports, double wooders etc etc or find that the room mode is as high as say 120Hz and all speakers set it off to some degree? I would say that with proper correction most speakers could work to the maximum of the rooms and their potential - isn't that what we really want? |
