HZ.....How low for full range music???

I have an elaborate array of subwoofers, and for some music, organ in particular, they have plenty to do. But, my main speakers are Maggie MG1.6, and they fall off fast at 40 Hz. However, the Maggies, when used without subwoofer help, (but with a 600 watt amp) actually sound as if they have "good bass" for most music. I have heard it said that their SMOOTH frequency response is the reason.

My experience indicates that the quality of the bass response is more important than how low it goes. Measures that a speaker designer can use to extend LF response can achieve that goal, but often results in "boomy" bass that sounds impressive in the showroom, but becomes annoying at home.

GREAT INFORMATION!!!!!!!!!!! THANKS A BUNCH

It is awfully hard to find "full range" speakers that go down to
20Hz and the ones that do, are usually very expensive. I agree with
Eldartford, I would rather have limited range speakers than speakers that do
bass badly -- and, to my ears, there are many, many speakers that do bass
badly. If you are listening to rock music, you probably want some bass slam.
Getting that slam will be a function of two things; Speakers capable of that
bass and amplifiers that can control the speakers. Most likely, you're talking
about solid state amplifier and you'll need a fair amount of power. I would
call any speaker that can give a relatively flat response down to the mid
twenties, "full range."

As far as room response, you can go to various web-sites and feed the
dimensions of your room into a simulator and it will predict the frequency
response of your room. Having fed lots and lots of dimensions into these
simulators, it seems to me that most rooms have large peaks and valleys
between 35Hz and 100Hz.

This is why many acoustical consultants recommend using a sub-woofer with
a parametic equalizer -- to smooth out the bass response in the room.

Here is one of those room simulators --

electric bass goes down to 41 hz. organ can go down into the 20's. it depends what you listen to. blues , rock, jazz and most music are happy with 40 hz performance. pro sound PA and bass gear is built to go down to 40 hz, so other than organ and home theater we don't get to hear much music below 40 hz, live or recorded.
