Stuck at home? Make a speaker or something for goodness sake!

Yeah I know, it's something I say twice a year at least, but I say it because I think our community is made better with more builders than with just buyers.

Hey I just finished mine.

I'd say it was a success.

Forgot to hook up one speaker's  W18  cabinet.
Still you get a  good idea how this speaker sounds.

This morning I figured out that DApolliyo and Seas Transmission line bass horn idea, was not sucha  good idea after all.
So I blocked off the bottom chamber going to the rear port, and cut a  new port in the front and 
Now we have front firing bass.
SUCCESS!!!
I'd say my front firing port is superior to DApollito and Seas's concept of rear horn port.
Dapollito and Seas figured
**gee with dual woofers and only 1 tweet, we need a  balance, lets port rear, and reflect off back wall, for a  more numanced bass respnse soas not to over whelm the single Millennium**
= wrong.
The issue is the Millennium has a  low db sens at 87 and the W18's also suffer from a  low db sens at 87.
I installeda  far superior tweet witha  Kasun 3.5 double magnet paper cone tweet at 91db and added the DL 6.5 for added boost to the 100hz-say 12khz.
SUCCESS.
Bass from the front baffel now balances out the voicing from the DavidLouis 91 wide band and Kasu 91db tweet.

Again , 1 speaker's W18's are not connected.
I'll have to make another video later

I think my speaker is~~ The~~~ Speaker to beat.

DavidLouis part 2, 
Both w18's are now Up N running, In my exceitment to try out the front firing baffel, I forgot earlier to hook up one cahnnel's w18's. 
All 4 now firing away

The vid abruptly ends as the Sony cam has tiny card memory.

The components are out there to make beautiful pure high fidelity music.
It only takes
~~~The Creative Mind~~
To seek out these possibilities and make it happen
As in my newest latest design.
You too can own a  world class SHF speaker.
Sure folks said
**ohh you can't do that**, well I broke all the rules and pay off was high fidelity.

mozartfan,
What tools do you use to design proper crossovers for these projects?

No I have no xover exp.
What I did was, tear out the brand new Millenniums, 
The xover was easy to tear out , as I had madisound redo my old xovers and had the bass xover and tweet xover on SEPARATE boards.
OK so Milleeium gone + xover partion gone
Now we are left with the fantastic dual W19E001's,. 
Remain in place
xover tweaked, took out the 8.2 installeda   10uf Supreme Silver. cut off now is like,,,say 1600hzish??
Now what are we going to do for 1600hz on up...hummm, lets try a  wide band
ceck
Order Voxativ AC1A. 
after a  10 ,,make that 5 minute trial in open and also ina  12inch1inch12inch  1/2 inch play cabinet=
Listed and sold at 1300/free ship, Gone
, back to drawing board... 
huummm back to davidLouis.. 
4 inch = SUCESS
Lets try the big brother 6.5
Success
Lets add some top end sheen
Add a  paper cone 3.5 inch double magnet Kasun
Check SUccess!!!
+ a  Mundorf 2.2 SESGO ($100 EACH!!!) ripped from Millennium xover.
Ck, sweet shiny sparkly highs, say 9kishfq =,,hummm , maybe 15k+hz's. 
DavidLouis runs wide open, no xover, just straight juice.
BBasically i have TWO!!!!!!! Caps in this Frankenstein
a  10uf/W18's
2.2/Kasun paper tweet.

Clean, clear,  near zero distortion,  near zero coloration, near zero fatigue, ona  scale of
1-100
1 being lowest possibel, ~~~~100 being like    Bose or B&W type coloration/distortion/fatigue.

It does not have as wide a sound stage as  say a  dual  W22 Graphene + DavidLouis 8 inch + Kasun 3.5 paper double magnet. . 
That speaker would compete with the best, any Wislon speaker in terms of width and breath of soundstage.

The Kasun might need a xover design to voice superior, but I have no access to any measurements nor software to design a  xover, So a simple 2.2 cap is all I can give it. 
And it sounds wonderful. Vocals accurate, clean, highs shimmer and sparkle. 
Is the Seas T35 better? I have no idea. 
I'm done with buying high priced tweets. 
The Crescendo was a huge disappoi9ntment. 
I will have it shiped to madisound for testing. If Madisound shows tweet working as new, = a  POS, sens is no more than 82db, IF THAT!!!!
Seas claims 92db.
Off by a  factor of 10db = trash. 
IMHO The kasun is the tweet to beat. 91 TRUE db sens.
