Product Research
Features
Tweeter: The 3/4" polyester fabric dome tweeter uses a neodymium magnet and includes a reflection absorbing and diffusing foam pad to smooth the high frequency output.
Waveguide: The tweeter includes a small waveguide designed to boost the tweeter's low frequencies and ensure a smooth transition to the midrange.
Crossover: Frequency division is controlled by a 12dB/octave high pass filter and 6dB/octave low pass filter. The entire crossover network is mounted to a PC board integrated into the basket, which also secures the terminals.
Power Handling: Audiofrog lists two RMS power figures in the manual; 50 watts RMS in the technical specifications section and 15-75 watts RMS in the recommendations section.

I needed some 4" speakers that could handle high power from my existing multichannel amp and took a chance on these. The audio quality is excellent and the grilles have a nice, understated look.
