Horowitz once said, "Not everything is a competition." The truth and importance of that statement notwithstanding, my nomination for the best Christmas album everyone must hear is "A Carnegie Hall Christmas Concert" Sony Classical CD 1992.

The new Era Design 4 review includes using two Sub 10 subwoofers. Why two? And if it is has to do with the rather high cross-over frequency, I wonder if a single subwoofer coupled with the Design 5s (which go a fair bit lower) might be a better value overall?

What does the impedence look like at the low end of a speaker that uses a powered woofer? Do they load the input of the amplifier and just waste power to create a uniform load or since most amplifiers are a low impedence voltage source do they just let the impedence increase at the low end?

I just got through reading Jason Victor Serinus's last 2 articles relating to how we judge audio "quality" in "How we see it". He has a real point when he notes that many (if not most) people don't use live acoustic sound as a reference and judge audio qualities very subjectively based on what they "like". I am a strong believer in using real unamplified instruments (including) voice as THE ultimate reference for how a piece of audio gear should sound. It is said that humans have poor "audio" memory but strangely I have found this to be completely false.
