Vandersteen Quattro CT with the tweeter out of the famous Model 7, Powered built in sub, 11 bands of analog EQ below 120 hz so you can place for best image, then correct most room issues, magic midrange enabled by high passing your main amp. Cabinet within a cabinet construction so the box isn’t contributing to output….Pistonic drivers, each speaker crossover tuned for the bespoke drivers in the anechoic chamber here in California… established company around since 1977, I just tuned a glorious sounding pair up… -2db at 20 hz in a big room… Manley tube monoblocks,,,, ah.
Of course at $15 k, you have many choices - enjoy the search and journey.
Of course i own other speakers….. but i’m a Vandy fan
