Speaker recommendations welcomed

I'm always somewhat mystified by room size dictating speaker size. Do people sit 30 feet back from the speakers in large rooms? My listening space is in a large room with 18 foot ceilings, 20X30 feet or something, and I sit with my ears maybe 9 feet from the speakers in one end of the room. Efficient horns with 2 subs, and I rarely crank it up much except when I want the sound to bleed into the kitchen when cooking. I'm not an EDM freak having drunk dance parties (I admit drinking can lead to a volume increase, but I don't drink much). Get whatever speakers you like with whatever amp suits you, and the room won't care. One of my amps (Dennis Had tube SEP) fills this room with a massive 12 watts PC and the other is a Pass XA-25 with somewhat more power...doesn't matter...one bit.

I'm starting to move away from Goldenear (or any powered speaker Meridian,etc.) simply because I don't want to worry about an internal amplifier failing.  Not 100% eliminated but hesitant.

I don't care what people say...Bose 901s series 2.

I went with the MoFi Sourcepoint 888’s. I chose them over the SvS Evolution Zpinnacles because they simply sound so much more natural and relaxed. In comparison The SVS high end was too forward and the bottom octaves to bombastic for my taste. 

So here is a somewhat out of left field, eccentric suggestion: original Quad electrostatics refurbished by Electrostatic Solutions (Kent McCollum). He uses thinner diaphragm material and gets better HF response and higher SPL levels compared to the originals.

Advantages:

THE classic speaker: Hi Fi News and Record Reviews Greatest Component of the 20th century.

They are superbly detailed at lower SPLs, and the refurbished versions can play louder than original Quads

One of the, if not THE best midranges ever, even by modern standards

One of the best amp matches is the relatively inexpensive Rogue Audio Atlas Magnum (per Robin Wyatt of Robyatt Audio, who tried out two dozen amps back around 2006 along with David Chesky and Gary Krakow, reported in Planar Speaker Asylum).

Disadvantages:

Not for live rock levels (but those levels can also cause permanent hearing loss). Your room is somewhat large for the Quads  but there is nothing that says you can't sit relatively close (6-8 feet away) and that should minimize room effects as the direct sound should predominate. Put them a third of the way into the room and fiddle around a bit for the best location.

No low bass -  but good to about 45-50 Hz. Ken Kessler of Hi Fi News was mightily impressed by David Chesky's McCollum upgraded Quads playing bass heavy reggae at levels he associated more with Wilson Alexandrias and such larger speakers.

Limited dispersion, best for a single listener, someone compared them to giant headphones.
