6.5 vs 8 vs 10 woofer

I was with you in the wideband hi-eff thread, but this 10" theory makes little sense.



~~~~~~~~~~~~
Not sure what topic i posted, that i am now of the opinion, dual 6.5's  superior toa  single 8 or 10.
The Seas Excel W18 are so well behaved in 40hz- 1500hz. that  really makes this a  full rich voicing in this critical register. 
On heavy complex  passages of 50hz/lower as in some Schnittke symphonies when all hell breaks lose, the W18's do get a  bit befuddled. 8 or 10 is better in this short passages.
But its not very often this attack of  50hz/lower makes its appearance in such an onslaught violence.
The W18 are not cheap, But as with anything in speakers, you get what you pay for. If you want the best gotta pay.
The newest Excel line is the Graphene, add  another 25%. Beasts!
So yeah dual Excel W18;'s in my opinion delivers the fullest bass of any design in the 40+ hz- say through  2000.  vs a   single bass woofer, 
Conside, how many 20-40 hz's are in your music? 
Well jazz, maybe,,,, but orchestra, not enough in that range to be noticed that its missing. 
The Excel W18's exhibit a   purity in the lower mid's  which is just laid-back, , natural, zero distortion/fatigue.
They are 87db, so only used  as a  ~filler~, adding  a ~subtle~wider/deeper soundstage in those fq's = 40hz-2000hz. when joined with a  FR. Preferably a  6.5 FR.
 But since Vox offers the 6 inch FR same price as 8, I'll opt for the 8. 

OK to recap,
A single 6.5 FR will not  offer ~slam~ in the 40hz-60hz. You will need some bass configure. 
A single 8 FR may offer some deeper bass in the 30hz-50hz, but not ~deep/rick/thick~ for some  some critical recordings. 
Bottom line: Dual 6.5's MM (skip the tweet) is the ideal bass configure for backing up a  single FR 6.5 or 8. 
A good quality FR does not require adding a  compression tweet. 
I'm kind of  joining up ~best of both worlds~ some depth in  the 40-60hz_ from the dual 6.5 low eff 87 db midbass, and then the critcal midrange of 100hz-5k with the high eff  FR. 
This configure may not work with the Vox, can't say til i acutally set it up. 
But with a  lower budget priced FR8  requires adding some sort of bass configure.

@mozartfan  I'm sorry, I don't mean to be rude, but you are clueless. 
You can certainly find An example of each of the above, but making blanket statements is naive. 

Such as ~all dome tweeters~ suffer from any number of weakness.??
The Millenium Tweeter is one of if not the best dome tweeter in production. Yet i've found its nothing vs a  high quality FR driver in the same fq's. 
Its ridiculous listening to a  tiny 1.3 inch dome tweeter trying to gather up a  full range orchestra in full power.
Its a joke.


Perhaps  a opinionated bias on my part,  but true. Dome tweeters are for jazz only. Light jazz at best. 

I agree with  with Larryi. As a speaker builder I respect his angle on design, implementation as in the right woofer for cabinet volume and other factors as in component selection. Cross over selection. Internal cabling, internal damping materials.  There are advantages in smaller drivers, and larger ones. My first were 14" Alinco Aquadag woofer with 5" mid ,2" tweeter.  The woofer had been in a larger room and was great .  I would not want them in a small room.  Now I live in a smaller space and the less efficient 8" towers I built are better suited for that room size. The bass actually goes lower on the 8" towers but in a large room would not have the same impact as compaired where they now sit.   Placing a pair of Klipshorns in a small room would be a disaster.  Matching components to the living space is very important.

@mozartfan,

" Its ridiculous listening to a tiny 1.3 inch dome tweeter trying to gather up a full range orchestra in full power."

tweeters reproduce harmonics mostly and are used over 2khz. listen to your music, turn a EQ on and highpass your orchestra at 2khz. not much energy over 2khz.

no wideband will be as even in the treble as any tweeter. and very few wideband, if any, of the zie your looking at (6 or 8") will reproduce "air" in a even pattern. Most wideband still need a tweeter for the last octave (10khz to 20khz)

its quite ridiculous to think that a wideband is suited to reproduce a orchestra at full power

Enjoy the journey, but everything is a compromise and many ways to get to satisfaction in this hobby

" Dual 6.5’s MM (skip the tweet) is the ideal bass configure for backing up a single FR 6.5 or 8."
why not dual 15", or dual 10’s or dual 8’s.

you clearly are starting to make stuff up as you go on.
