Well thanks for that info. none the less I still have very good hearing (according to my audiologist) you need to take into account that you calculations assume that each ear is no more than one meter from my speaker and of course your talking about a continuous tone at that wattage level rather than a regular rise and fall in the music. trust me its not that loud

If the system is in an enclosed space the reverberant field takes over and you will not lose 6db for every doubling of distance.
6db per doubling of distance only occurs in open space. Even outdoors, if there are buildings or other things that the sound can bounce off of, you don't lose 6db every time you double the distance.
You would in an anechoic chamber.
In most living rooms, with direct radiator type speakers, the reverberant field starts at about 39" (how convenient is that?).
I use direct radiators and the volume stays the same no matter where I am in the room except for a little bass build up in the corners.
BTW 12db (going from 4 to 16 feet away from a speaker in open space) is a large volume difference. I have a stepped volume control, 2db per step. Six clicks up is a lot louder.
I can move from 4' to 16' away from my speakers in my living room and except for the aforementioned bass buildup, 2db maybe, there's virtually no change in volume.

"Still Working the Problem"
Tre' Be that as it may, I still have concerns using the red rose R3's with a 30 watt triode, when I have a problem driving them with a 120 watt amp, maybe I need to add a powered sub to bring up the bass a bit... not a big fan of powered subs, or maybe i just need to do some room treatments to get it right. (that might be difficult my wife already thinks I nuts... She may be right) at any rate I will try the amp on the R3's when it arrives and consider after that weather I want a higher efficiency speaker. I hate to get rid of the R3's they are a one of the best speakers I have ever heard! Searching for audio nirvana I guess. I was looking at the full range speakers, as a bit of an experiment... I'm sure you all know what that is like, my stereo equipment tens to change slowly over time, some I regret letting go others not so much.. the R3's I think I will keep regardless. but have not been that impressed with the Krell amp, it is accurate the imaging is good but it lacks the warmth that I had with my conrad johnson...that I should have kept! Than ks all I will look up the reviews on the lowthers at stereophile and consider the hersheys.

Get an almond Hershey.
Seriously, if you like the speakers you have keep them and find a tube amp that will drive them. Perfection does not exist in this hobby and you can go broke and nuts. AA sponsor Jim Mc Shane does wonders with Citations.
