The Polk Audio Signature Elite ES90 speaker system is a high—quality 2.0 passive speaker designed for audiophiles who appreciate detailed and natural sound. Thanks to its sophisticated design and the use of advanced materials, the speakers deliver a wide and precise frequency range, spanning from 52 Hz to 40,000 Hz, allowing for both deep bass and clear, airy treble.
Each speaker is equipped with two radiators:
133.35 mm (5.25 in) woofer/midrange speaker with mica—reinforced polypropylene diffuser provides durability, rigidity and minimal distortion in the mid and low range.
25.4mm (1 inch) terylene fabric dome tweeter — responsible for clear and soft transmission of high frequencies with high resolution.
The acoustic design is of the bass reflex type, which allows you to amplify low frequencies and increase the overall efficiency of the system, providing a richer and more dynamic sound even at moderate power.
Speakers are recommended to be connected to an amplifier with a power of 20 to 150 watts, which makes them versatile for use both in home audio systems and as part of a Hi-Fi stereo pair. The resistance is 4 or 8 ohms, which ensures compatibility with a wide range of amplifiers.
The crossover separation frequency is 2200 Hz, which guarantees a clear signal distribution between the emitters and minimizes range overlap. The sensitivity is 85 dB, which indicates good playback efficiency.
The case is made of MDF (medium—density fiberboard), a material that minimizes resonances and vibrations, ensuring a clear sound. The kit includes two speakers, which allows you to assemble a high-quality stereo pair.
There are no wireless interfaces, as the system is designed for wired connection to an external amplifier or receiver, which corresponds to the philosophy of Hi-Fi audio technology.
The Polk Audio Signature Elite ES90 is a combination of advanced acoustic technology, high—quality materials and careful sound tuning, making them an excellent choice for those looking for authentic and immersive music playback at home.
