Thanks, Dave... I've since had another brainstorm and have requested a quote for a different finish (among other things) in an e-mail I sent you a few days ago. I'll wait for a personal reply.
A question about specs-- I see that the towers are rated at 4 ohm average impedance. But wondering if the wattages listed for recommended power, maximum continuous power, maximum peak power are into 8 ohms or 4 ohms? In other words, should my power amp be rated at 300 wpc into 8 ohm or 4 ohm to match continuous power rating? This info isn't going to determine which amp I get, but was just wondering.
I'll add that I'm also curious about this. When I was doing my homework on which speakers to buy, I think I decided it's customary for this to always be for 8 ohms, but now that I think about it, "watts is watts" as it's a measure of the rate of power delivery (joules/sec) regardless of the impedance, so I am quite looking forward to the answer.
Unless I'm mistaken, I believe the towers are rated at 8ohm average and 4ohm minimal.

Since the Sierras were first released, I've been fascinated by the variable slope crossover capabilites of the Sierras that help to mitigate phase anomalies between the drivers. I am curious as to how this is possible (seems to me it might require a variable capacitor?), if a quick explanation (in layman's terms) is possible, and also if those same phase aligning principles are used in the Sierra Towers?

Hi Jay,
Without revealing too much info, the crossover slopes on the Sierra-1 are not "continuously" variable. A typical crossover slope decays at the same rate, for example, energy is reduced 24dB per octave. In a variable slope crossover, energy might be reduced at 12dB per octave for a specific frequency bandwidth and then increased to 24dB per octave for another frequency bandwidth. We use this in all of our loudspeakers...
