HELVIA ONDA-540TFW 5.25" WHITE RECESSED SPEAKER
Estimated delivery in Italy between 30 October and 3 November
2-WAY 5.25" FLUSH-MOUNT SPEAKER WHITE FRAMELESS
The ONDA series of flush-mount speakers is designed to meet all those indoor installations where higher sound pressure levels and audio quality are required compared to standard 70/100V distribution systems. ONDA speakers are all low-impedance (8ohm), coaxial, with kevlar woofer, silk dome tweeter, precision crossover; essentially true professional 2-way speakers in flush-mount format. The look of the front surface is minimalist and appealing, echoing that of reference monitors from professional recording studios. The frameless design, with black ABS frame and white magnetic grilles, makes ONDA speakers extremely discreet. The grilles can finally be repainted to make them even less visible.
