6.5 vs 8 vs 10 woofer


IMHO I think the 8 is the ideal size cone for mid/small sized listening rooms. Even for large size listening rooms. 
The lower mid hz's seem cleaner/clearer. And  there is so little fq's in 905+ of the music we listen to, it seems to me the 8  driver is the most perfect size cone.
A 10 size cone  has the potential to become overwheling, aggressive, attacking when amp gain is pushed just a  tad too much, = Better  volume  control with a  8 vs a 10. 
The 6.5 misses some of that lower bass which a  8 can voice superior. 
After listening to several YT vids with a  10 FR, I had considered going 10, but i think  staying with a  8 avoids regrets. 
I listen at low/mid volume.

Wow!  I'm Not Sure..  Crazy!  the time we all have that is Free Time, on this..  is All..
I remember way back when...before the popularity of (invention of home) subwoofers... 8" was considered the 'proper' woofer size in many a sealed box 2 way system. 
I also agree no one size fits all!
My more 'conventional' speakers are 6.5s' with a passive for speed, to keep pace with Heil amt's.  Below that, a pair of 10" backed by a small sub for impact on demand.

The Walsh only need the sub for 'bottom'. *s*  Same for the Maggies.

Between the 3, I can adjust for the media du jour. ;)

The only 'one size fits all'....is a hanky.
Mozartfan is a very suitable handle.
His dogmatic unevidenced statements seem to be formed from the scientific knowledge available in the eighteenth century.
The voice coils caught fire less than half an hour into the first band's set. LITERALLY CAUGHT FIRE.

Richard Gray did advise , that I am going in the very opposite direction as his Atmosphere 2.8watt SWET with 83db eff speakers, 
While the Atmos owner burnt up his SET amp, <<like 3x's>>?? according to Richard's testimony, That I would witha  100 pure watt PP amplifier <<Litterally Fry the 98 db speakers>>
This morning as i awaoke, i realized, just at what vol level on the linestage jadis can I turn before i have << high db level>> 
Might have to get that Italian step attenuator for $300 have Ricahrd install, 
OR sell off the Defy7 and make a offer on Richard;s 250 tube SET amplifier he  designed, its all attached to a  piece of plywood, , but thats neither here nor there, Its how does it sound.
After I get the 8's up N running I will test the 2 amps. 

I mean even with the 6.5 Diatone, the vol knob hardly ever goes past 9 oclock, if that. 
94db, then 98 db, now i am beginning to understand all this SET vs PP paired with super high FR speakers.
Got it.
