Which speakers will fill 5,000 cubic ft coherently

Springbok, I now understand your desire not to switch amps, but I'm still not sure about the limitations about where you can place the loudspeaker. It's highly unlikely that a speaker of the performance you are considering will work optimally in the narrowly prescribed area you can position them. You may have boxed yourself into a coffin -- so to speak.

Springbok,

Why not try pulling those beautiful Kharma's well out into the room and away from the side walls....(while the wife is out) and see if it sounds better?

Shadorne, exactly what I suggested in Springbok's last thread.

Of course it does sound better, but a) the wife always comes back :)and I'm not having speakers on roller skates - ; b)it still doesnt fill the room - every audio "authority" (manufacturer of note, if you like) that I have spoken to is amazed that I would expect a small 2-way speaker to fill 56oo cubic feet. Do you think it should/would/could? My stupidity for not thinking of this/ trying it out before buying them.

Appropos your comments about Ralph, Tvad, I have spoken to him today and he confirms his generalisation that 8 ohm impedances are better for all tube amps; however, he believes that he should re-state his assertion, since it is taken too literally (I don't want to put words in his mouth and maybe he will chime in here) - he believes the MA-2 can easily drive the Tyler Woodmere, with its benign impedance curve, but states that it would sound even better with an 8 ohm, rather than 4 ohm, impedance. So that doesn't disqualify a 4 ohm speaker for mating with the MA-2, since the speaker's 91 db sensitivity will compensate somewhat. But the Woodmere doesn't have a 60 day trial like the Zu Definition, so a trial could be "hazardous", and I've done that once already..........I suppose to get as close to "perfection", all the known criteria should ideally be met, and a higher impedance than 6 ohms is one of them, so your point is valid.
