• Woofer Master Audio of 10,00 cm of diameter (4") very powerful and very compact with black cone in cellulose and suspension in foam. The impedance is 8 ohm therefore and proper for uses in the house, dj, disco, system dolby surround and other. Excellent also for fittings in car where is possible to install is singly them, both to couple or also more pieces for door. The frequency reponse is 100 - 6000 hz. The relationship quality' / price is elevated
• This woofer can be amplified by the radio of series. Is possible to apply 30 watt rms channel to get the good result. To avoid irreparable damages to the woofer not to overcome the powers recommended from the house
