A full range speaker?

Many claim to be, but how many can handle a full orchestra’s range?

That range is from 26hz to around 12khz including harmonics, but the speakers that can go that low are few and far between. That is a shame, since the grand piano, one of the center points of many orchestral and symphonic performances, needs that lower range to produce a low A fully, however little that key is used.

I used to think it was 32hz, which would handle a Hammond B-3’s full keyboard, so cover most of the musical instruments range, but since having subs have realized how much I am missing without those going down to 25hz with no db’s down.

What would you set as the lower limit of music reproduction for a speaker to be called full range?

 I’m asking you to consider that point where that measurement is -0db’s, which is always different from published spec's.

I’m settling for 18” short throw paper cone, extremely light and ridged, right now in my studio. And at about ⅓ power it feels perfect.

~~~~~~~~~~~~~~~~~~

I'll consder looking at your 18 inch woofer, Also Lii has  some high sens 15 inch woofers on the cheap, like $300 a  PAIR!!!
I will also conisder those as a  possibility. I have no idea what the bass will be with the 8 inch wide band. The lab claims  20hz. 
If it is true the speaker goes down to 20hz, I feel no need to bring in any 15 inch/18 inch sub woofer.
Now it will all be out of balance. 
Besides, my room is only 10x12/8 ceiling. 
A 15 or 18 will not work.

For a 15 or 18 woofer, one needs at least 20x20x10/,minimum

Some audiophiles are obsessed with this **fantasy* 20hz-40hz region.
I'm not sure why you think achieving good LF is an obsession or fantasy.
This range represents only 1% of the actual music. = There is nothing there
There's more there than you realize. Once you've heard it it's difficult to forsake - LF is the foundation of the music, imo.

pragmasi196 posts07-14-2021 6:43amThis may be useful for some - here's a Sound on Sound page with a link to a frequency chart in the top right corner. Fundamental notes are within the range of 16Hz to 9kHz, with harmonics going much further up in frequency. If you don't listen to a lot of pipe organ music then a lower bound of 30Hz will include all the fundamentals

~~~~~~~~~~~~~~~~~~~~~
Intuitively I figured there was not much below say 40hz, 
And this chart shows the truth of the fq range of  clasical symphony orchesra.

This explains why I can not accepta  dome tweeter for my classical muisc. 
There is too many notes bombarding this crucial region for a  3/4 inch voice coil to handle. 

For those who listen to mostly classical music, your dome tweeter is not  **delivering the goods***
You need to go wide band to have a  orchestra symphony/chamber sound **Live**.

For jazz fans, the dome tweeter is acceptable.
But  why not go wide band, this way you get your jazz and classical voiced beautifully. 
I just do not see any more need for dome tweeters, They served us well these  past 50 years, its time to let them go.

You have to forget about fundamentals. Things like the thumb striking low E produce a thump that is below the fundamental. Percussion will do this also. Music and venues also breath. There is a lot that happens below 40 Hz that provides the sense of a live performance. Without it you will never feel as if you are at a live performance. Many people give up on this issue thinking that HiFi's can't possibly do this. Bad assumption. They certainly can. It takes the right tonal balance, imaging and low bass to pull it off. 

William53, it is much harder to control a large cone, to keep them moving in a straight line and not flexing. I prefer multiple smaller drivers. The effect is the same with less distortion. My new subs will use a total of 8 12" drivers.

Just took a pic on my CP and blew it up to read.
Man I tell you,
~~~The real meat of the muisc starts at 150hz~~~~
Sure the low string on the cello is 60hz, THE LOWEST NOTE that is,, = rarely played.

~~~~ The music starts at 160hz~~~~
Which completely validates my strong belief wide bands are the bomb.
You take + have your Wilson.s
Wide band is the only speaker I can listen to.
Why??
All the music is represented in all its fullest richest, deepest, colors. With zero coration. zero fatigue.
Wison’s $360G’s..,,oh its full range all right,, but also full of something else, called deep coloration and distortions.
