Acoustics Dynavoice Challenger M-65 Black

The Dynavoice Challenger M-65 has been perfected in several ways. The speaker cabinet turned out to be as inert as possible. This provides true Hi-Fi sound without internal resonances. The body walls are made of 18mm MDF with lots of spacers. The HF and MF chambers are isolated from each other, thereby eliminating distortion. Overall, the Dynavoice Challenger M-65 has a very strong and rigid body. The weight of one column is 27 kg. The body of the acoustics is covered with a “wood-like” film, and the front panel is trimmed with piano lacquer to give the whole structure a status appearance.

There are three gold-plated jumpered connectors at the top of the terminal strip. It is used to adjust the high/mid range. You can select a return of -2 dB / 0 dB / +2 dB / +4 dB. Swapping the jumper means changing the nature of the sound of acoustics in the range from 4 kHz to 20 kHz. This way you don't have to adjust the treble on the amplifier to get the sound you want. In the schematic image next to X-Change, you can see how moving the jumper will affect the sound.

Without a jumper, the treble/midrange response drops by 2 dB. With a jumper - the output level will change by the number of dB written between the holes.
