The Sound of Speaker.

"...They use to fill the base with sand and tune that Watson..."

I think you meant to say Watkins? 

I never consider myself as an expert about speaker, I just have experienced owning some Magnepan, Dahlquist, AR9, JBL250, Martin Logan, KEF, Mission, Rega, Tannoy etc...
I am still using Rega Ela in my Reading-room and there are 5 set of Stereo system in my BR, Garage, LR, RR and DR.
I don't have nor I wanna  have thick-skin just to be able to share a hobby that I love, so I guess I was in the wrong place.
I will sign-out and maybe I could find a different forum where I can share this hobby and where some members not trying to look good by insulting each other.
Good luck all and Good-bye!.
       

"...to use the word "Prejudice" seems too harsh I think..."

Yes, perhaps it was but I try to tell people to keep an open mind and discard preconceived notions because there is fabulous gear in every design configuration. Never discount gear due to the design, listen first. We all have our favorites but I'm willing to try or hear as many designs as possible. Some products work and some don't but they deserve a listen first. 

Prejudice?
Sounds like aprejudice to me.
Happy that you found what you like.
If you are there, an open mind won't improve your life any.

Tannoys dual concentric drivers have a unique sound that can take some getting used to. However, once you do, there is no returning to other speakers, jmo.
