I have 300 sq ft to fill with sound, so I’m in need of larger speakers. I also dislike the sound of the employment of full range quasi ribbons in the new .7 series. It sounds phasey to me. And the true ribbons don’t sound coherent with the rest of the drivers in the older large models. I’ve auditioned the 3.7s in my home and preferred the sound of my 1.6s except for the better bass extension in the 3 series. 2.7s would be the best of both worlds.
