HELVI A ONDA-B660FCW 6.5"+1.5" 2-WAY IN-WALL HI-FI SPEAKER, WHITE
Estimated delivery in Italy between 22 and 24 July
FEATURES
ONDA B660FCW is a powerful and precise 2-way speaker, with a 6" high-excursion woofer and a 1.5" tweeter delivering 60W RMS of power. It can be used with both standard 70/100V professional amplifiers and low impedance (8 ohm) amplifiers, offering transparent and brilliant sound. The presence of the rear cabinet with two front bass reflex ports allows for emphasis on the mid-low frequency response, providing a much warmer and enveloping sound even without the acoustic box effect due to the false ceiling, which is necessary for traditional ceiling speakers. Installation is extremely simple, thanks to the quick mounting system, hidden behind the grille, which offers an elegant and minimalist design. The integrated line transformers allow use with 70/100V lines and offer 5 power taps plus 8 ohms to best adapt to different speaker configurations and amplification powers. The connector is a 4-pin Euroblock type (2 plus - 2 minus, for easy connection to other speakers) and is located on the front panel along with the power selector. This greatly facilitates the assembly and installation of the speaker even if it is already fixed to the ceiling.
