Прослухав з Luxman M-02 C-02, неміг відірватись, наче новий світ відкрив, мені здається вони непіддались впливу часу...просто таки заворожливий саунд...буду і далі слухати...взувають на голову багатьох в 3-4 рази дорожчих варіантів.

Drivers
The four drivers of the Marantz HD77s are a woofer, mid-range, tweeter and super tweeter. The given frequency responses are what the crossover circuit feed to each speaker, not what each speaker would respond to with no crossover circuit(full spectrum). The mid-range, tweeter and super tweeter have crossover controls for switching between a laboratory "flat" +/- 0db neutral response and a "room EQ" response. Tested frequency response is measured in an anechoic chamber from 20 Hz to 20 kHz, and displayed in a graph shown in original Marantz brochure. Crossover and frequency response are two different things. Crossover points are established for each driver and their specified frequency range. Without crossover points, the drivers would distort and likely overheat and burn out due to the production of the full spectrum of frequencies, with exception of the woofer which inherently struggles with producing higher frequencies. The drivers together create a complete spectrum frequency response.

Woofer
The woofer is 12 inches (30 cm) in diameter with a frequency response of 30 to 500 hertz.

Mid-range
The mid-range is 4.5 inches in diameter with a frequency response of 500 hertz to 3 kilohertz.

Tweeter
The tweeter is a 2-inch (5.1 cm) LPF film dome-type. The tweeter's frequency response is from 3 kHz to 8 kHz.

Super tweeter
The super tweeter is a 1-inch LPF film dome with response from 8 to 23 kHz, which extends 3 kHz above the nominal range of audio frequencies which can be heard by the human ear.
