The JA Perspectives 2 use two magnesium 5 1/2 inch Seas. The graphene is only a coating used as a corrosion inhibitor and perhaps small amount of stiffness. Mine have all the bass I like you will feel it.
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
