A full range speaker?

How many W18’s?


~~~~~~~~~~~~~~~~~~
Dual, thats 2 per channel.
sens is 86 db, very low,
which is why Seas uses 2 per channel,
They use the E001 and not the EX001.
I would rather have the EX001 fora few $’s more, bigger magnet, = more kick in low bass.
I guess they wanted a balance (E001 more recessed bass vs the EX001), competeing  with the single Millennium tweet.

Best bang speaker would be
Dual W22 EX’s per channel, + a Crescendo = a Super Thor.
The Crescendo is far superior to the old Seas Flagship the Millennium. For same price. 
I have a single Crescendo now, , so that project is on hold til I find cash for a  second unit..
 which i will be running with a 8.2 cap, = 3200hz.
The W18’s roll off at say 1600hz
So the 1600hz-3200hz will be carried by the davidLouis 4 inch wide band,,which rolls off at say 80ish hz and maybe like 10k-12khzish,,Not sure.
But definetly has some highs.
bass not bad for a lil 4 incher.
Mids, all there, with vocals very accurate.
hardly any coloration/distoryion,,so fatigue is never a issue (no resonances due to some treatment on the paper cone material, = does not have a paper composite sound, not at all.
Its 91db.
How it compares to its bigger brother the 6.5 incher,,will soon know late this week. when it arrives via Honk Kong seller.
I am expecting alottt more bang out the 6.5,,as a 4 inch cone is very tiny = can’t really open up on bass.
So here is the 4 in action, no tweeter and forgot to unplug one channel’s W18’s.
Still you get a good idea of the voicing of this lil guy
Wilson offers a $960k signature speaker,w hich clarly beats out this oil 4 inch wide band.
However if I hear even the slightest coloration in any of Wislon’s mid range fq’s. Then I’ll have to say, this lil 4 inch beats Wislon in the fatigue category.
This is the problem with any speaker trying to acheive all fq range, price no object.
My tech friend has the Rat Shak Nova 7B’s with the paper composite cones, He loves his Noa 7B’ s stacked...I HATE anything paper, if its not treated with some coating. Even witha coati9ng it brings back old feelings from speakers of the 1970’s.
A sound I wish to be as far away from as possible.
Which is why I luckily went with magnesium, = Has no lower bass/lower mid resonances that I hear in paper.
I believe Scanspeak in the Wilson’s are paper composite. And for this reason, I could never live with any of the Wilson line.

I get the feeling

*Been there done that**
I do not need crystaline highs,,, deep rock solid bass.
In the Wilson’s you get both.

Thats not what I am after.
My goal has been to try eliminate as much coloration as possible hopefully resulting in as close to zero fatigue as possible.
I am getting closer and closer to this goal, with the DavidLouis 6.5 + Crescendo.

The Crescendo Project is a ways off. Short on cash right now..

Many claim to be, but how many can handle a full orchestra’s range?

~~~~~~~~~~~~~~~~~
This  is my best pic of any speaker other than DIY of course that can handle/voice full symphony orchestra in all its colors dynamics, with no coloration. 
Unlike Wilson's which in fact do have fatigue
This Seas has zero fatigue. 
I know I own Seas.
Zero fatigue. Wilson's although FR , have coloration of muddy grey's, in  upper bass.

william53b OP166 posts08-05-2021 11:35amVery nice.
I like Seas drivers as well, but also Eton Symphony’s, and Scan Speak Revelators.

~~~~~~~~~~~~~~~~~~
Troel Gravesen uses both Eton and scan's, both excellent speakers,,
Here is my brief biase and heavy prejudiced review of the build on the DL 6.5 which just arrived, Tech is out of shop, so a  listen will have to wait til tomorrow .


I did say BIASEd and PRE-judiced.

Now think concentric driver with a whizzer for better off axis and phase plug for back wave distortion reduction.

My question is can you still keep the acoustic center of the two drivers and use the correct phase plug to stop the back wave (BASS), from the rear/side walls first reflection.

Hypothetically the HF driver would have to be set inside the phase plug or Open Baffle the HF driver backwards.. (I’ve seen that).. and it works if the rest of the driver system is in a box, bipoled the opposite direction.
(I haven’t seen that)


~~~~~~~~~~~~~~~~~~~~~
Wayyy over my head, 
btw what is 
~~~HF~~~

I really have no idea what you are descriving.
Anyway. My DavidLouis 6.5 whizzer wide band just arrived , Up N running. 
Very nice gain over the DL4 incher wide band.
Added some bass, , mids are claener, highs not rolled off. = A WINNER.
$450 includes ship
 The Crescendo/Seas wasa HUGEEEE disappointment, Seas claims 92db, My tech hook it to his sens gadget,, maybe 85db, when i hooked it up to a  Mundorf 2.2 Supreme cap,,I COULD HARDLY HEAR IT ,, I;d say its more like 83db,,which means I have to ship it off to madisound for testing,, No way seas would lie.. We will find  out if something is wrong,,Bought it as new off ebay auction,

Anyway,,I'd say this DL 6.5 is the very best wide band in production
versus\
Fesatrex, 
AER
Voxativ.
Yep, thats my 2 cent opinion, The DL  at $450, needing NO HORN cabinet, just a  12 inch x 12 inch x 12 inch sanded ply from Home Depot, cut in 4 1 inch port hole at each corner = and you have a  $20 cabinet.
I just feel the big 3 labs will not hold up against the DL 6.5.
No have not heard the big 3 , all models,, only the Vox AC1A, 
The DL completely totally annihilates and destroys the Voxatiiv AC1A 's @ $2k.
Davidlouis Gold Standard in Wide band.
I'd take this DL6.5 over any Wislon and Vandersteen 

Enjoy

Some tech geek in china, knows how to build a  wide band.

Keep in mind the 6550's have more than ~~~2k~~ hours,,
all the sheen is rubed off. Still in all, this lil wide band delivers stunning highs. Exteremely accurate, with no coloration , zero fatigue = 
SUCCESS!!!!
Did not come cheap. 
I am the only YTer showing off the DavidLouis.

Dis the above DL video, This is DL part 2. I am telling you, this lil wide band delivers rich detailed  nass/mids/highs. 
I would not trade this DL6.5 for any speaker on the market.
Not even the Wilson top line.

Read what it says over a few times and it will make sense.. We want it, in your head, not over your head. :-)

~~~~~~~~~~~~~~
Yes I looked over the Tannoy's. Interesting,, Seas also has a  ~~Co-axil__.
Interesting if you read the descript, Seas says they designed this ~~concentric~~  with the highest regards for super high fidelity.
Again, interesting. 
But note, Seas says  bass is 150hz, more as a  midrange-tweet.

https://www.madisoundspeakerstore.com/coaxial/seas-excel-c18en002/a-e0060-6.5-coaxial-each/
I am sure the Seas along with a  Seas W22 Graphene would be a  nice speaker, caveat $$$$$$$$./
So I went with the 
DavidLouis wide band @ 91 ~~TRUE!!!~ sens and bass does in fact hit the 60hz, if not 50hz before roll off. 
Mids/vocals are accurate and nothing harsh nor  showing signs of stress at moderate db levels on gain.
Highs are there, rolling off, maybe like 13k/14kish. 
= highs are sweet and satisfactory.
So for $450 its right in my budget, vs the layout for the Tannoys  which I may have some issues with either in the bass/, mids or highs.
I have no issues whatsoever in the DL 6.5
This lil DL 6.5 is the speaker to beat out ina  shootout  IMHO/2 cents worth.

Here's another demo of the DL6.5 in action,.
Its everything i hoped for in a  speaker. My experiements , though costly, have paid off.

 The DavidLouis has no other YT  uploads except on my channel. I will be making a  long series of vids over the next weeks showing just what this speaker is capable.



https://www.youtube.com/watch?v=-h8TRoILZEg&t=2s

Its just that none, zero , of the commercial speakers interest me.
So that is why I had to design my own speaker, w/o any advice, suggestions, ideas from my tech geek nor anyone here on audiogon.
I had to make my own design, nilly willy, for the good or the bad.
Tried this, that, then swaped out that, for this, and so on.
Til finally i have pretty much my Final Speaker til death. 
You could not even give me a  speaker to replace my own design. 
You may not like it, but thing is , its my music, my ears, and this speaker is as close to my perfect ideal of how a speaker should voice.
Again, you might say ***THAT!!**

And I will respond, Its as close to my hopes of speaker nirvana, more than I could ever expect.
Each person has to come to his own ideas/experiences of how he wishes his ideal speaker to voice.
I have plans to add a  DL8, the white cone wide band
Will bea  shootout twix the 
DL 6.5 Neodymium
vs
DL 8/Ferrite magnet weighing in at a  blsitering 8 lbs!!!!!!!!!, Woden cone
One heck of a  shootout.
One or the other will be champ of wide bands.
My guess is I'll like things about both and so keep both. Swap out, depends on the music selection. 
Sort of adding spice and variety.

So like yeah, my speaker is all original, my ideas, no one elses.

 the Lii Silver 10

~~~~~~~~~~~~~~~~
I had the LII Fast 8, the older model.
There was not even 1 thing I liked about that wide band
I quickly dumped it on ebay at 1/2 what i paid. 
I am experimenting with various Davidlouis, IMHO the DL's are the best bang wide band.
No I have not heard every AER/Voxativ
I did hear the Voxativ AC1A and  they were LESS THAN the cheap LII garbage. 
I have serious doubts to the performance of the AER/Voxativ.
