Rapidly approaching the staggering state observed among inveterate show attendees on Friday evening, I stumbled upon the debut of Duke Lejeune’s $4000/pair Jazz Modules. Note that the speakers were not intended specifically for jazz; the name came to Duke in a dream as he was preparing to graduate from amateur speaker builder to fledgling audiophile professional. With a claimed sensitvity of 92dB, the speakers extend from the upper 30s to about 17.5kHz. Port tuning is changeable according to listening position. Even with only two days of break-in—the woofers require several hundred hours to sound their best, Duke told me—the speakers threw a huge soundstage, and sounded remarkably full, warm and luscious in the midrange, I felt.
