Speakers for a Large Room (20’x37’)

AT is a legacy and kef dealer so would know best but the blade is rated at 117 max spl. Klipsch highs were always too splashy for me and they seem to be a love em or leave em brand. There's a pair of meridian dsp 8000's on auction right now that will get it done and sound great while being fully active.

I like the blades as well. 91db efficiency but for a large space I like that it sounds good over the entire listening area. Many of the speakers mentioned have a small sweet spot, but the blades sound good over a much larger area

I own klipsch speakers, but i only find them suitable for home theater. While the RF7 3’s are not the most expensive speakers Klipsch sell, I can tell you they are some of the worst sounding speakers (for music) that I have ever heard. Even matched with high end equipment in a great room there was nothing I could do to make them sound good. It’s not just about how loud a speaker will go, it’s also about how good it sounds. Two thumbs down to klipsch

A lot of ppl here are only mentioning high spl/ high sensitivity speakers. If thats all that mattered i could easily recommend a cheap pair of horn speakers that will rock your socks off.

However, SOUND QUALITY MATTERS. not just how loud it is or how easy it is to drive

Magico Q7s would make for a satisfactorily larger room filling and bank account emptying experience, I would think.

I have a room bigger than that with a balcony and cathedral ceiling and I use my Polk Lism707 and they sound Great and so do other people ,I have had over  Ok there not Audiophiles, just human beings ...lol.

Humans are ok.
