BTW, the other speakers in the room include the modified JBL L200s (with increased cabinet volume, L300 long horns, slot tweeters, revised crossovers), one-off Big Red Supers (Altec 604E2s/Utah aux woofers) triamped with one-off electronic crossover and Marantz power amps), and Chartwell LS3/5As.
Room is 26’ x 16’ x 7.5-16 feet and about 5,000 cu ft.
None of these other speakers soundstage/image like the "Mermans" (so named for Ethel because of her loud and clear voice and disrespect for authority).
