Which speakers will fill 5,000 cubic ft coherently

>>3-18-08 Shadorne: 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?<<

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.

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.

A speaker's impedance and sensitivity are two completely different things, and one does not compensate for the other.

A sensitivity rating (91 dB) tells you how loudly a speaker will play given 1 watt of power measured 1 meter from the drivers. It tells you how effectively the speakers will fill your room with sound.

The speaker's impedance tells you if its tonality will be balanced and natural given a particular amplifier. Improperly matched impedance will result in a tone that's either unbalanced from top to bottom (i.e. a speaker sounds bright because the highs are louder than the mids and bass), or sounds unnatural (for essentially the same reason).

I'm interested to know how you or Ralph are determining that the Woodmere speakers have a benign impedance curve since the minimum impedance spec of the Woodmere is not published on the Tyler webpage. Ty only publishes the nominal impedance spec.

Based on Ty telling me it is an easy load and drops to low-mid 3's.

I'm not arguing about any of your points, tvad, just reporting what Ralph said based on Ty's conversation and Ralph's knowledge of the speakers.

What this implies, if taken literally, is that no 4 ohm speaker should be driven by a tube amp. Period. I'd be interested to know how many audiophiles follow this rule. Anybody out there drive a Woodmere with any tube amp?
Does thais imply that all speakers with 4 ohm impedances are ruling out tube amps to drive them? I'd be interested to hear other speaker manufacturers' comments.

Read my post carefully. I conceded that it would/could be a mis-match.

So now I am looking at speakers that look great (WAF), have a small footprint, have 13 0hm impedance and can stand 6-12" from the wall - Selah Audio Alexandrite. Long build-time, but who's in a rush? Any comments?
