Speakers for a Large Room (20’x37’)

JBL Everest DD67000

@doni I just think the Blade are the best speaker I have ever heard. There are aspeakers with a little better drivers out there (for ex. Yamaha NS5000). However, the way the Blades project the soundstage in unsurpased with every other speaker I have heard. I have gone to a a few shows and have heard a lot of gear. There are also incredible audio stores in Southern California. So I am not basing my comment from limited experience.

BTW - the Yamaha NS5000 is also an incredible 'bookshelf" speaker that would likely be great in your large space. You can get a home demo of them from 2 online sellers. I expect to get the NS5000 over the Blade because the side firing Blades are a bit more difficult to place in my living room. I have a local NS5000 dealer.

BTW2 - I expect the KEF Blades to be upgraded soon with the META technology that came with the most recent LS50's.

I just read the @audiotroy comment about the Blade and loud volume. I never new that. So maybe the Blade recommendation is something to question if you play really loud (I don’t).

Last month I was in a room with top end Legacy speakers driven by a CODA #16 amp and those speakers will really fill a large room. I also heard them a few years ago in a large hotel room and the room was too small for them. Not a big Legacy fan though but they have a huge sound.

I also see @verdantaudio commenting on the Vivid Kaya line. I really like those speakers too. I was planning to get the Magico A3 for my office until I heard the Kaya 90 (I was interested in the Kaya 45). I thought it was a better speaker with more coherent sound. However, the side firing woofers made me relunctant to get them even after I spoke the the guys from Vivid. They said the side firing woofers would not cause a problem in my room which have drywall and outside brick. I went with the safer pick of the Thiel CS3.7.

Audiotroy's point has come up before.  Years ago over in Stereophile forum, I had made a comment on the LS50s and he argued they had an issue at high volumes due to the tweeter limiting excursion.  This would extend to any speaker using the UniQ driver and even showed it in a measurement plot they provided.

I am not a Kef dealer or expert and can't speak to it.  Only that I have heard it raised as an issue previously.  I will tell you that Vivids will not have this problem.  And, even though you would think it would be an issue, near wall placement with those side firing woofers is not an issue.  I have tested it on my Kaya 45s.  I am not sure how or why it works, it just does.  
 

Doni,

My room is 16'6/' X  34 with cathedral ceiling. I use custom  built Tannoys using HPD 315 drivers. I only sit about 9' from the speakers. They really work well for me.

You can see for yourself in Done For Now, under the name of "The Summit". 

That refers to my summit, not inferring it is at the top of everone's heap.

Good luck with your search, regards,

Dan
