5-03-09: TvadSo claims Silverline, but the href=http://www.stereophile.com/floorloudspeakers/307silver/index4.html>
The Mirage speakers are almost 42" tall... 2" taller than the
Preludes, and the Mirage go down to 52Hz wheres the Preludes go to
35Hz.
Stereophile measurements indicate the Preludes are down 10dB at 50
Hz, so I'd bet the Mirages' bass is at least as strong with its three woofers,
five passive radiators, and ribbed elliptical surrounds.
Also the test indicates that in spite of Silverline's claimed 91dB sensitivity, it
measured 87.5dB, which is about the same as the Totem Arro.
By the way, I just checked the specs on the Totem Arro, and it's factory-rated
as a 4-ohm loudspeaker. Your problem with your current amp is probably
current delivery, not power. I suspect you are using a tube amp and its high
output impedance isn't up to the current demands of the Arro. Any chance
your amp has 4-ohm taps?
