Tannoy Westminister VS dc10 Instrument Grande V

looking for a large formal loudspeaker for our fairly large formal den 28x40 12 foot ceiling oak floors the space is open and not cluttered I'm not looking for magico even though they are my neighbors and don't like the looks of the big Wilson's plus they are too $$$ I want something that looks like real wood is very efficient and is 50K or less!

I'm actually replacing old Klipsh Le Scalas.

I think the Tannoy top of the line with alnico mags is the ticket as it will integrate into our built in cabinets very very well and the look is 90% of the equation even though my gut tells me that the Grand Voix has more of a real reference hifi sound and the Tannoy more of a one speaker sound.

Thanks for the info now to find a dealer!
I would add JBL Everests and Cessaro (not sure if its in your budget) to your list.
The JBL does not look formal to me or my partner. We want something with the right aesthetic cohesion for the room and the Tannoy is about perfect looks wise I'm only worried that they will have that "quacky" one driver sound.

The dc10 audio is a little flashy with the two horns but I like how they look just the same and based on their components they must sound pretty damn good though they will not integrate quite as well as the Westminster and are more money, and no one has ever heard them..

I'm still confused!

While I cannot read into your individual sonic preferences, I think I understand what you're afraid of and can confirm the Wests sound nothing like that.
I lived with a pair years ago and found the sound very good: I enjoyed my BB King as much as I enjoyed symphonic Mahler. The sonic result had vivacity, energy, and dynamic impact. The instruments had sufficient weight ("flesh") and even a full orchestra sounded palpable. A recent model I listened to is better I think (IIRC the old sound!), it is more extended in the upper frequencies and, thereby, more dynamic and "clearer".

WHile I cant readily compare to your La Scala, I know the Klipschorns and IMO the Tannoys are better. BTW, the Klipschorns still an excellent speaker as well...

(BTW, there is a driver within the driver, rather than single driver -- it is actually a sort of two-way.)
