Gladen Beta 165.2

The Gladen BETA 165.2 is a high-quality 2-way component system designed to deliver natural, precise, and balanced sound reproduction in the vehicle. As part of the Gladen BETA series, it offers a significant improvement in sound quality compared to many stock speaker systems and impresses with its efficient power handling and harmonious tuning.

The 165 mm paper-cone mid-bass drivers deliver clean midrange reproduction and a controlled, dynamic bass response. The combination of a Nomex suspension, a 25 mm KSV voice coil, and a soft dust cap enables precise, low-distortion music reproduction.

25-mm silk dome tweeters with rear-mounted resonance chambers are used to deliver clear and detailed highs. The compact passive crossovers, with a crossover frequency of 3,500 Hz and a slope of 12 dB/octave, ensure a smooth transition between the low-midrange driver and the tweeter. The built-in level adjustment allows the treble range to be attenuated by 3 dB if desired.

Thanks to its 3-ohm impedance and high sensitivity of 93 dB, the Gladen BETA 165.2 is suitable for both direct connection to compatible car stereos and use with external car audio amplifiers.
