Among the many accolades he has received are Grammy awards and nominations, a Guggenheim Fellowship, and a MacArthur Fellowship (known as the "Genius Grant"). He has lived at or near the top of the major jazz polls for years on his instrument, the alto saxophone.

Zenón did not start out with any…

Like many audiophiles, I've found myself intrigued by the variety of approaches that are taken to achieve the same goals: point…

Step two is to set the relative levels of the midrange and highs using two sturdy three-way switches, choosing among 0, +1.5dB, and –1.5dB for treble and midrange. The crossover from the midrange horns to the treble horns is at 3.5kHz, a frequency that conveniently caps the fundamental frequencies of common musical instruments. (On a standard piano, the four highest notes, including the black keys, are in the range of the tweeter; the rest are in the midrange.) I went back and forth but ultimately left the tweeter flat and set the midrange level to +1.5dB.

Next, I adjusted the…
