A full range speaker?

mijostyn4,659 posts07-14-2021 7:10amdjones, a rising response from 100 Hz down to 20 Hz with 20 Hz up 6 dB does not produce fat bass. Fat bass is produced by a peak in the 80 to 160 Hz region. Pushing the response up at 20 Hz gives you that sense of a live performance at less than ear shattering levels. Push it too high and the bass becomes disjointed, you know you are listening subwoofers. You should never know you are listening to subwoofers.

Yet another lzaer guided missle.
I mean this post really nails it.
Subs are *boomy** = un-musical, = anti=musical = anti high fidelity, 
Bug deal your sub goes to 10hz, I could care less. 
its Your subs 80-160hz region that makes ** fat* *Ugly* *Boomy* bass distortion, = YUCKKKKyyyy
I HATE subs.
40hz is really all you want, as pragmasi has very convincingly shown and proved.
Troel pretty much says the same thing about his dual W18's per channel MMT speakers. 
**paraphrasing **although it does not go below the 40hz, it SEEMS as though the bass hits well below 40hz**
A 6.5 midwoofer will have a  superior 80hz-160 hz voicing, cleaner, clearer vs a sub. 
Some audiophiles are obsessed with this **fantasy* 20hz-40hz region. 
This range represents only 1% of the actual music. = There is nothing there
 Why go chasing this region  employing all sorts of crappy bass woofers??
Get over it. 

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

I'm not sure why you think achieving good LF is an obsession or fantasy.

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.
