Concerto Grosso

Floor-standing speaker, 4-way base reflex configuration with additional passive radiator

The greatest concert master ever – only the best components are good enough for the top-of-the-range model in the Heco speaker portfolio, now available to mark Heco´s anniversary. High-gloss paintwork and an MDG housing with multiple bracing to ensure a highly stable design ensure even the highest demands for sound quality will be satisfied.
This can also be seen in the chassis features of the impressive box over 1.30 meters in size: A 300 mm woofer, installed as side driver, and a 300 mm bass radiator are supplemented by a 200 mm woofer/midrange driver, a 170 mm midrange driver and a 30 mm dome tweeter. With a frequency response beginning at a sensational 16 Hz and only ending at 52 kHz, the Concerto Grosso guarantees perfect reproduction of any signal source – including high-resolution audio files, like those highly sought after by discerning music lovers.
