I was listening tonight to the Szell/Cleveland "Live In Tokyo" Sibelius Second. I always thought it the very best example of a non-audiophile recording as well as one of the Clevelanders best efforts. And Szell died just 3 months later.........
Anyhow, it sounded better than ever; more "live", more "dynamic" and all the instruments with breath and tone; downbows and sharp pizzicato attacks.
It struck me that perhaps I had struck a better balance between the low and high frequency drivers.
On Patricia Barber's "Cafe Blue" I heard brushes on the snares together with the well-known 8 foot apart cymbals that were lost before.
And on James Taylor "Hourglass" the skins of the big Tom-toms stretched even further on Gaia.
That's not hi-fi detail, that's balance.
The Altec Heritage site says that the 902-B is 107dB efficient. I have a 30 Ohm shunt and 60 Ohm series resistor together with the .47 cap. The crossover is 16 ohms but the driver is 8.
You want to think the 902-B at coming in at 1200 Hz is overpowering the 2226 but it isn't.
Is it?
