Recommendations for speakers that sound great at lower volume levels.

I don’t own Tannoys  , now they will be no longer made in the U.K
i would never even consider buying them now ,China specials 
same price point, No thanks.

Spatial Audio Labs X3, and X 5 open baffle speakers.

A truly great speaker in which I am saving for and heard many times. 97db efficient ,8 ohms very minimal Xover 3 parts , the Spatial Audio Labs Open Baffle X3, X5   Great Custom Beyma AMT tweeter-Midrange driver in a wave guide,from 1k to -30 khz , 12 inch midbass
From under 1k to 90 Hz then Hypex power Bass to 25 HZ 
x5 12 inch woofer, X3 -15 inch woofer 
$6995 is a steal it beats speakers 2-3x the monies. In my tri state audio club I have heard dozens of quality speakers . I didnot think 
open baffle would be good , I was very wrong ,no box colorations 
fast open and great detail , imaging microdynamics at a whisper 
to thunderous loud and even a small amp of 15-20 watts ,at 97 db 
efficient ,verygood .one highly rated upgrade , VH Audio Odam capacitors I believe 2 per speaker  msybe a $5-600 upgrade 
and worth everypenny . They even have I believe a 60 day return policy .Clayton is great to work with .I owned his original 4 open baffle these are night and day better.

For great new Higher end speaker Marten Oscars very good across the board  and very fair priced vs the competition 
and noticeably better IMO.
