SEAS Excel Magnesium Midwoofer 51/2 inches ROCK SOLID BASS

Just measured the  edge of surround, it is 5 1/2 inches across.
I am getting TONs or ROCK SOLID BASS.
Does anyone still believe in the woofer theory, bigger is better??

Especially taking room size into acct, Yeah if you havea  palace size room, maybe you want to fill it with bass, soa  8 inch/10 ibch might work for you
I think we should always bring up room size in discussion ofa  ideal speaker bass response.
also note, bass is bass,, well not really, Cone material and how cone is labed makes a  big difference. This SEAS Excel has FREE moving  membrane around the solid copper phase pluf. 
also in considertion is how well doesa  mid woofer/woofer  both voice the upper low fq's to meet  with either a  midrange(which i hate) and a  midtweet. 
I think SEAS hit on the perfect idea of allowing the come to move freely indepent of the solid copper phase plug. 
 Giving a  natural bass response  and adding  the fullest possible bass extention due to its undersized 5.5 cone. 
+ its my guess this magnesiusm material is superior to the old standard paper. 
I know B& W also boasts a  unique cone material, that cool looking yellow fabric,,but i am not at all keen on how their midwoofers voice the upper low fq's. Its too colored for my taste.
So yeah I bought a  sub system to catch the lowest fq's, but as my tech guy says, ,, for what? and suggested that dayton sub amp witha   Cerwin Vega 10 inch,, will only add some dull boominess, with no fidelity (have both for sale on Craiglist cheap) , I always believed maybe I should try to gather the lowest fq's missing in the 5.5 inch midwoofers,,, But really there is not much going on in the 20-30 hz area anyway. 
It would only add this dull  boomy noise.

Somehow Seas Tested and figured out the 5 1/2 inch mid is the best of both worlds,, meets the required low fq register and also meets the Millennium midtweet at a  higher fq  junction making ita  seamless transparent high fidelity image.
At least thats what i am now finally hearing after  upgrading  and repairing my newly acquired Jadis DPL.
IOW the Thors have come alive after all these 18 years when driven with high quality components. 

The Q is,  what is the advantage of havinga  woofer larger than 6/7 (foam edge to foam edge) inches in a speaker design? To what benifit?
Also we should consider how a   specific 6/7 midwoofer voices the upper low fq's that meet the midtweeter. 
This could bea  issue, where the tweet has one particular voice and the widwoifer has a  slightly dif voicing. 
=  will sound like crap.
I think Seas tested all these  critical parimeters and came up with theie Excel line, some 20 years ago,, I am now curious to their new Flagship design the Cresendo + Nextel midwoofer 2 way.
Taking High Fidelity into the 21st century and ,,,beyond.....
I am on the fence should i add this Bifrost as a 2nd speaker,,, or upgrade my Thors xover with all Mundorf Silver caps/ ULTRA resistors/ top of line coils

40 Hz down to 18 Hz

I mean, yeah OK, there does exit some of these fq's in music that go below 40hz,, but how much,, = less than 1% of the music,, = no I do not need large box speakers. 
These dual 5 1/2 inch drivers deliver heart throbbing SLAMMMM
 a  8 inch , even worse 10 inch for my size room would be over kill.  and sloppy, a  5 1/2 i inch midbass puts out tigher deeper real hifi bass vs a  8 or 10 inch woofer. 
The SEAS 5.5 midbass made 8 and 10 inch obsolete dinosaurs.  This technology over 20 years ago. 
Get with the times man,

I don't know if it's the exact same model, but doesn't Joseph Audio use these in the Perspective?
Graphene, of course, is a whole other story.

I wrote about this phenomenon in a recent thread:

Just read through some of your excellent spot on research,, My findings are indenpent and thought i was the only one here who is bringing awareness of this revelation,, = That big is not always better and in this particular case, big is NOT superior. In fact worse in most ideal listing rooms size.
The Sacnspeak Revelator says 7 incjh,,,but from  rubber surround edge to edge its as the SEAS Excel 7 inch, 5 1/5 inch. 
I have no doubt in the lower bass fq's  the Revelator may surpass the Excel,,,but then in other higher fq's , I am not so sure for MY personal preferences. That revelator is one heck of a  midbass no doubt. 
So gald you have made these observations public and thereby  bringing enlightening EDU nto us audiophiles which , as you know can be easily persuaded into thinking we really needa  8 inch woofer. 
We don't, 
The 5 1/5 inchmidwoofer is not only odeal, but is absolutely perfection  in reproducing true super high fidelity bass. 
8 inch woofer may be acceptable,, but when compared next toa  7 incj, the altter will always win out.,,,,, 10 inch is obsolete in most listening enviornments. 
This Bifrost offers a  8 inch midwoofer and is paired with the SEAS Flagship Cresendo,,But is the Nextel  8 superior to the Excel 7 ??

I have this same Jacnitha cd, and will upload a  YT vid and post it here,, you tell me which mid is superior,,keep in mind this Bifrost has far superior mic vs my Sony.
The Bifrost sounds warmer, = if warmer is your thing, maybe the Bifrost is your choice,,But then  how are the other components voicing the muisc?? 
Hard to determine.

While I think that it is good to let audiophiles know how much bass these modest mid-woofers can produce, it’s also not fair to claim it is the only way to go.

In modest living rooms, when not seeking concert level rock output these systems can be the best balanced, simplest alternatives.

At the same time, for dynamic range and deep frequencies it is also true that nothing beats surface area and displacement. The issue is the balance of the speaker to the room, and how the audiophile will deal with the issues as they come up.

I am by no means against subwoofers, or big drivers at all. I do think however that trying to use speakers that go down to 20 Hz in an anechoic is a terrible idea in the wrong room and can ruin an otherwise superb experience, much like The Cheesecake Factory has ruined cheesecake with too many extras.


Best,

if we consider size/weight/price/power draw/over all fq resiolution/soundstage, the 5 1/2 incher draws a quick gun.
